PREFACE.

The completion of the present volume brings the Third Series of 6 The Ibis to a close. Pressure of other duties preventing my continuing the sole charge of the Journal, Mr. P. L. Sclater has, with the approval of a Meeting of the British Ornitho¬ logists’ Union held in May last, consented to join me in editing a Pourth Series, which will he com¬ menced in January next.

In thanking the many contributors to the pages of ‘The Ibis’ for their support during my past term of office as Editor, I beg leave on behalf of Mr. Sclater and myself to solicit their further aid in maintaining the high character ‘The Ibis’ has hitherto borne in advancing the science of Orni¬ thology.

I. Second Thoughts on the Genus Micrastur. By Robert Ridgway, of the Ornithological Department, U.S. National Museum, Washington*

Having recently examined the entire series of the smaller members of this genus contained in the collection of Messrs. Salvin and Godman, sent to me for that purpose, I have been induced, to modify to some extent my views given in the Proceedings 5 of the Boston Society of Natural History for 1873.

The series is a splendid one, and has, I think, enabled me to get the right idea of the species of this exceedingly per¬ plexing group.

Setting M. melanoleucus (sive semitorquatus ”) and M. mirandoltii aside, as being distinct enough to need no notice in connexion with the smaller species, I identify the names of previous authors as follows :

Sparvius ruficollis, Vieill., = M. ruficollis, Scl. & Salv., rufous phase, adult.

Sparvius gilvicollis, Vieill.*, —M. leucauchen, Scl. & Salv.,

* This cannot, according to the terms of the diagnosis, he M gilvi - collis, Scl. & Salv., if the latter = my concentricus, which = concentricus of SER. III. - VOL. VI. B

2 Mr. R. Ridgway on the Genus Micrastur.

M. gilvicollis, Pelz. Orn. Voy. Novara ( = M. ruficollis, plum¬ beous phase, adult) .

Falco leucauchen, Temm., = M. ruficollis , Scl. & Salv., rufous phase (?), young.

Falco sc ant hot hor ax, Temm .,=M. ruficollis, rufous adult.

Nisus concentricus, Less.,, is undeterminable ; and if tbe type does not exist, the name may be thrown aside as entirely worthless, though Pelzeln distinguished a very distinct species by this name, which should be adopted for that bird* *.

Micrastur guerilla, Cass.,=M. guerilla, Scl. & Salv.

Micrastur zonothorax, Cabanis,=M. zonothorax, Scl. & Salv.

My M. leucauchen (paper in Pr. Boston Soc.) is the young of M. leucauchen of Scl. & Salv. ; and they, together, are young and old plumages of M. ruficollis.

I was certainly wrong in referring so many of the recog¬ nized forms to one species ; but this was partly owing to the impossibility of making desirable comparisons.

Before proceeding to give a diagnosis of the species I now distinguish, it will be best to make a few remarks regarding the stages of plumage assumed by them, and which, if clearly borne in mind, will remove the greatest obstacle towards understanding the species. In the first place, there is no sexual difference in coloration, beyond what results from irregular variations of an individual character ; in the next place, in M. guerilla and M. ruficollis, there are two quite different phases 93 of plumage, corresponding in every par¬ ticular to the grey and rufous plumages of certain Owls (notably Scops, Glaucidium, and Syrnium aluco), and which are most unquestionably entirely independent of sex, age, or season. The grey phase may be taken as the normal one, since the other is merely the evidence of a colour-variation,

Pelzeln. It is distinctly stated to have the posterior lower parts barred, which the latter has not ; and there are other points which point to M. leucauchen, Scl. & Salv. [At our request Mr. D. G. Elliot searched for Vieillot’s type of M. gilvicollis in the Paris Museum, hut failed to find it. We now think, with Mr. Ridgway, that the name M. concentricus had best he used for the Guiana bird. Ed.]

* [Lesson’s type does exist, and is doubtless the bird here called M. concentricus , and also by v. Pelzeln. Ed.]

Mr. R. Ridgway on the Genus Micrastur.

termed by Pelzeln erythrism,” and entirely analogous to the condition of melanism. The condition is most exaggerated in M. ruficollis, but it is plainly visible in M. guerilla. No rufous specimens have been seen of M, concentricus , Pelz., nor M. pelzelni ; and, on the other hand,, I have seen no plumbeous examples of M. zonothorax. But such probably occur, and should be borne in mind before any new form is described.

Synopsis of the Species of Micrastur.

A. Outer toe decidedly longer than the inner.

a. Size large (wing more than 8 inches).

1. Above black, with a nuchal collar of white or ochraceous.

M. melanoleucus*.

2. Above plumbeous, without a nuchal collar . . M. mirandollii.

b. Size small (wing less than 8 inches).

3. Wing 6-50-7T0, tail 6-90-7-50. Tail crossed by 3-6 (terminal

bar not counted) indistinct bars of white or pale greyish. Adult. Tail-bars 3-4; above plumbeous, the dorsal region sometimes chocolate; throat light grey; jugulum, breast, and entire lower parts barred with white and dusky. Young . Above dark clove- brown, plain or indistinctly spotted posteriorly ; beneath white or buff, rarely immaculate, usually coarsely barred.

M. guerilla.

4. Wing 6-90-7 'oO, tail 7‘60-8”40. Tail with 4-7 distinct white

bars. Adult. Above, including neck and most of head, rusty chocolate, less reddish anteriorly; throat light chocolate; jugu¬ lum and entire lower parts everywhere barred with white and dusky. Tail-bands 4-5. Young. Above dark sooty brown, in¬ distinctly barred with rusty ; crown and nape sooty black ; lower parts white or buff, rarely immaculate, usually barred, and with¬ out rufous tinge on the breast ; tail-bars 6-7. M. zonothorax.

5. Wing 6-60-7T0, tail 7 ‘30-7 -80. Tail with 4-8 usually distinct

white bars. Adult. Breast washed with rufous ; throat light grey ; other lower parts everywhere barred with white and dusky ; crown plumbeous ; other upper parts varying from clear light bluish plumbeous to rusty brown. Tail-bars 4. Young. Above varying from greyish brown to dark rusty chocolate ; throat and half-crescent behind the ear-coverts white, in abrupt contrast ; beneath white, coarsely barred with dusky brown

M. ruficollis .

* I cannot identify Sparvius semitorquatus, Vieill., with this species, since that is said to have the top of the head white, barred with black, whereas it is always plain black in this bird, which, in the adult plumage is S. melanoleucus, Vieill.

The following is a description of M. pelzelni :

Micrastur pelzelni, Ridgway.

Sp. Gh. Outer toe decidedly longer than the inner; tail shorter than the wing. Adult £* above uniform (continu¬ ous) dark plumbeous. Tail darker, narrowly tipped with white, and crossed by two narrow bands of dull brownish grey, becoming white on inner webs. Sides of head and neck plumbeous grey; throat light grey; rest of lower parts white, marked everywhere with narrow transverse bars of dark plumbeous or slate, these bars widest on the breast (where they are narrower than the white interspaces), and

narrowest on the flanks and crissum, where they are very distant. Wing 6*50 inches, tail 6*30, culmen *60, tarsus 2*30, middle toe F20.

Remarks, At first sight this species has a very close re¬ semblance to the plumbeous phase of M. guerilla ; but upon a close comparison it is found to differ essentially in having the tail shorter than the wing, instead of longer, and to be crossed by much fewer (two instead of three or four) light bars. With respect to the shortness of the tail, it agrees with M. concentricus ; but that species differs (not only from this, but all others of the genus) in having the lateral toes of nearly equal length, the outer, if either, being the shorter, and also in having the crissum unbarred white. M. mirandollii , one of the large species, alone agrees with the present bird in having the tail shorter than the wing, and, at the same time, the outer toe longer than the inner.

II. Remarks on some Type Specimens of Trochilidse from the

Museums of Neuchdtel and Florence . By D. G. Elliot,

F.R.S.E., F.L.S., &c.

The receipt of three of TschudFs types from the Museum of Neuchatel, through the kindness of M. Coulon, the director, has given me an opportunity of making several comparisons, the results of which may not perhaps be uninteresting to ornithologists.

Bourcieria insectivora.

Trochilus (. Lampornis)insectivorus , Tschudi, Fauna Peruana, p. 248, t. 28. f. 1.

Bourcieria insectivora , Gould, Intr. Troch. p. 135, sp. 278.

Hab. Peru.

In the f Fauna Peruana/ Tschudi described and figured a Humming-bird obtained by him between Huari and Chaga- cancha, at a height of 14,600 feet above the sea, in Peru, as Trochilus insectivorus . It was evidently either a young bird or a female ; and as, until lately, no other specimens than those obtained by Tschudi have reached us, naturalists have

6

Mr. D. Gr. Elliot on some

been in some doubt whether Tschudi's bird belonged to a distinct species, or to one already described ; at the same time the examples presented certain differences not reconcilable with any specimens in our collections. Through the kind¬ ness of M. Taczanowski, director of the Warsaw Museum, I have lately received a specimen of a fine adult male, shot by M. J elski in Peru, the country whence TschudPs bird came, and which, I have no doubt, I am right in attributing to B. insectivora. In order to satisfy ourselves in the matter, Mr. Salvin wrote to M. Coulon, at Neuchatel, for the loan of Tschudks type, a request which, with his characteristic libe¬ rality, was at once acceded to. On comparison it appears to be a female ; and therefore, as the male has never been de¬ scribed, and as it is quite different from any known species of Bourcieria, I have thought it might be useful for ornitho¬ logists to become acquainted with it in the adult dress. It is nearest to B. fulgidigula in the group to which it belongs, and not to B. conradi , as supposed by Mr. Gould. It may be described as follows :

Head and back of neck jet-black ; centre of the crown bril¬ liant metallic golden green, very bright and conspicuous. Throat metallic green, this colour extending over the sides of the neck, but much less brilliant, being a kind of metallic gloss on the black of that part. Back and upper tail-coverts metallic grass-green. Wings like the back, primaries pur¬ plish brown. Upper part of breast, extending to the green of the throat, pure white ; rest of underparts and under tail- coverts shining grass-green. Median tail-feathers shining grass-green; remainder pure white tipped with green, this last becoming more extensive as it proceeds towards the outer¬ most rectrices, which are nearly one third green from the tip, and running much further towards the base on the outer web than on the inner. The bill is long, straight, and pointed, black throughout. The feet flesh-colour.

The female (Tschudf’s type) differs in having the head, throat, and upper parts shining green, with none of the black observable in the male. Median rectrices green ; rest white, tipped with black glossed with green. The white is much

more extensive upon the tail-feathers than on those of the male ; hut this appears to be characteristic of the females of all the various species of the genus Bourcieria.

The present species is one of the very handsomest of this genus, being only exceeded in beauty by B. inca, Gould.

Hab. Venezuela, Columbia, Peru, Bolivia.

This bird was first described by Bourcier in the f Revue Zoologique-’ for April 1843, from New Granada; and in the same year Tschudi described and figured it from Peru as T. otero. Succeeding authors have kept these birds separate, notably Mr. Gould, founding the species upon the size, chiefly that of the bill. In his ' Introduction 9 to the Trochilidse, Mr. Gould further distinguishes the bird from Venezuela as Leadbeatera splendens, stating that it is allied to the Bolivian bird, but differs in having a straighter and shorter bill, and in the green tint of the under surface.” Lately Mr. Buckley has brought specimens from Chairo, in Bolivia, a place about 6000 feet above the sea ; and these are not to be distinguished from the Columbian bird. Tschudks type of Trochilus otero is quite a young bird, and in length of bill and general size is like specimens from Columbia ; while the Venezuelan birds, L. splendens, and adult so-called otero, from Bolivia, with the long bills, are, so far as I am able to see, precisely alike ; and intermediate lengths of bill are obtainable in specimens from

Mr. D. G. Elliot on some

Columbia and Bolivia respectively. Besides the great diffi¬ culty of recognizing more than one species by size (for there is absolutely no change of colour or brilliancy in the plumage to warrant any specific rank being granted to more than one form) , there is the geographical distribution of the species. If three species are to be accepted, we find that L. splendens in the north is separated from L. otero in Bolivia by L. grata of Columbia, and that the last two become mingled toge¬ ther in Bolivia not at all a probable state of things for really distinct species. As in many groups of Humming¬ birds, a variability in size of bill and length of wing, and perhaps also of tail, is discernible ; but if these, unsup¬ ported by other more important characters, are to be accepted as always denoting distinct species, much confusion is certain to be the result, and no limit can be fixed beyond which any naturalist, possessed with keen sight and enthusiastic appre¬ ciation of minute difference, may not go. It may, however, be advanced, with much probability, that there is only one species of those birds consigned to the genus Leadbeateray whose range extends from V enezuela, through Columbia, into Bolivia, being somewhat variable in the size of the bills of indi¬ viduals from some localities, though it is almost certain that a large series of specimens would yield a regular series of in¬ termediate measurements. I do not see that Bonaparte had any reason for taking this bird out of the genus Heliodooca , and, therefore, have not adopted his term.

This species, first procured by Tschudi in Peru, has received

Type Specimens of Trochilidse. 9

many names by different authors. The specimens with white spots in the tail, which may possibly be females, were named by Mr. Gonld L. hypoleucus ; but this has been placed as a synonym of Tschudhs appellation by that naturalist. Re¬ cently Mr. Buckley has brought specimens from Bolivia, which, on comparison with TschudPs type, are found to be the same. This genus, therefore, will consist only of two species*, the present and the L. chlorocercus , Gould, de¬ scribed in the f Proceedings 9 of the Zoological Society for 1866, p. 194, which differs chiefly in having the throat spot¬ ted with brown, instead of being pure white. Tschudi’s bird was first described as T. leucogaster (loc. cit.), a name after¬ wards altered to T. chionogaster in the f Pauna Peruana f the name first applied must, of course, be the one adopted.

In the year 1865, in the f Annals * of the Florence Mu¬ seum, Sig. Benvenuti described four species of Humming¬ birds, coming from New Granada, as new. The descriptions given, and the comparisons made, did not indicate them as belonging to unknown forms ; but it was impossible to deter¬ mine their real specific value without having access to the examples themselves. Having requested Dr. Giglioli to for¬ ward the types to me, he most kindly sent three of them (all that were in the museum) ; and I am now able to determine

* In the P. Z. 8. for 1874, M. Taczanowski described a specimen of Leucippus as L. pallidus, from Peru, differing from L. leucogaster in being slightly larger, and having a nuance grisatre on the back and head. This is undoubtedly a Trochilus turner if Bourcier (Revue Zoologique 1846, p. 313), the type of which is in my collection, and which is cha¬ racterized in his description as haying la tete, cou, dos, couvertures alaires et caudales vert grisatre luisant.” This has long since been placed among the synonyms of L. leucogaster , as being simply a phase of plu¬ mage that is met with in nearly every group of the Trochilidse, where specimens are found that exhibit a colour slightly at variance with the typical style, as, for instance, yellowish green, or, as in this case, greyish green, instead of pure green. These differences, however, like those of slight variations in length of bill, wings, or tail, have no specific value. I have therefore placed L. pallidus among the synonyms of Ij. leucogaster ; for it does not seem to be at all necessary to elevate L. turneri into a separate species, of which L. pallidus of Taczanowski would certainly be a synonym.

these without any doubt whatever. The birds named were Polytmus (Campy lopterus) cecilia, Mellisuga ( Panoplites ) judith, Mellisuga ( Cynanthus ) salvadorii, and Mellisuga (Eri- ocnemis) ridolfii. The first of these I have not seen, as it is in the Museum of Turin ; but on writing to Count Salva- dori, he assures me that it is only a female of Campylopterus lazulus ; and I believe this identification to be perfectly cor¬ rect. The second is

Mellisuga (Panoplites) judith.

Mellisuga judith , Benv. Ann. del R. Mus. Elorent. 1865, p. 203, sp. 11.

This bird proves to be the Panoplites flavescens, with which Signor Benvenuti had compared it; and I cannot perceive that the differences given by him were in any way of suffi¬ cient consequence to cause him to give the specimen a new name. It is a male, in adult plumage; and the name of M. judith must become a synonym of P. flavescens.

The third was named

Mellisuga (Cynanthus) salvadorii.

Mellisuqa salvadorii , Benv. Ann. del B. Mus. Eloren. 1865, p. 204.

The type of this so-called species is an adult female of Cy¬ nanthus cyanurus in the ordinary state of plumage, such as is commonly observed in all the specimens of this sex com¬ ing from Bogota. There is nothing to distinguish it as dis¬ tinct ; and the name given by Sig. Benvenuti must become a synonym.

The last described is

Mellisuga (Eriocnemis) ridoleii.

Mellisuga ridolfii , Benv. Ann. del R. Mus. 1865, p. 205.

This bird, on examination, proves also to be a female of a well-known species, Eriocnemis vestita, one of the commonest and best-known among Humming-birds. The name ridolfii must sink into a synonym.

It is a pity that before naming these birds as distinct. Signor Benvenuti had not followed the advice given to him by M. Salle in the letter published in his article, and sent
