On Some Birds from Santa Marta, Colombia. 07 



Serpophaga cineiea grisea (Lawr.). 



Five specimens, from Chirua, San Miguel, and La Concepcion. These 

 are just like skins in the U. S. National Museum from Costa Rica— true 

 grisea of Lawrence — which seem.s to me to represent a perfectly good sub- 

 species, diftering considerably in color from true »S'. cinerea of P]cuador aiul 

 Peru. .Sclater, however, in the ' Catalogue of Birds in the British Museum ' 

 unites the two without a word. 



Myiopatis montensis * sp. nov. 



Eighteen specimens from Paramo de Macotama, ILOOO feet ; Macotama, 

 9,000 feet, and Paramo de Chiru(iua, 12,000 feet. 



Type from Paramo de Macotama, Colombia; altitude, 11,000 feet. No. 

 6112, fj' adult, coll. of E. A. and 0. Bangs. Collected U&r. 3, 1899, by 

 W. W. Brown, Jr. 



Specific c/««r«c/e?-s.— Much larger than M. semifuscn Scl., with much longer 

 tail ; bill longer and more slender, base of lower mandible black (yellowish 

 in semifusca) ; tertials not so large nor so broadly rounded at ends ; breast 

 darker olive ; pileum much darker than back. Sexes similar. 



Co^or.— Pileum dark grayish olive; back and rump olive; lores, supra- 

 orbital and supra-auricular streak, oi-bital ring, and most of auriculars 

 grayish; a dusky post-ocular streak ; wings dusky; wing coverts broadly 

 tipped with dull tawny ochraceous, forming two broad wing liars; outer 

 edges of secondaries tawny-ochraceous toward ends, wholly blackish at 

 base, thus forming a blackish patch on closed wing just behind the second 

 wing bar; edges and tips of tertials dull yellowish white (in some speci- 

 mens, all in worn plumage with abraded feathers, the wing bars and edges 

 of secondaries are all dull yellowish white) ; tail dusky, narrowly edged 

 with olive and sometimes (in fresh plumage) tipped with Isabella color; 

 tliroat grayish white ; lireast grayish olive; belly and under tail-coverts 

 primrose yellow; flanks olive; lining of wing and bend of wing pale 

 yellowish; bill wholly blackish. 



Measurements.— Ty-pQ, adult cf : Wing, 66.fi; tail, 69; tarsus, 20.2; ex- 

 posed culmen, 9.6. Adult $, No. 6104, from Macotama: Wing, 70; tail, 

 69; tarsus, 20.2; exposed culmen, 10. (These two examples exhibit the 

 extremes in wing measurement in the series of eighteen specimens.) 



Remarks.— \^ hen collecting in the lowlands and among the smaller 

 mountains near Santa INIarta, Mr. Brown took six examples of true M- 

 semifnscn. These are topotypes of the species. In the high mountains, 

 from altitudes of 9,000 to 12,000 feet, he secured a series of eighteen spec- 

 imens of a wholly different bird, which I have here called M. montensis. 

 The differences between the two are so great as to seem almost more than 

 specific; the very long tail, long slender, wholly black bill, and the dif- 

 ferently shaped tertials of the mountain bird are very marked characters. 



In ascending the mountains there seems to be a belt of from 6,000 to 

 9,000 feet wlfere neither M. semifusca nor M. montensis is found. This 



* Montensis, belonging to mountains.
