On Some Birds from Santa Marta, Colombia. 97 



Serpophaga cinerea giisea (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 seems to me to represent a perfectly good sub 

 species, differing considerably in color from true S. cinerea of Ecuador and 

 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, 1 1 ,000 feet ; Macotama, 

 9,OOD feet, and Paramo de Chiruqua, 12,000 feet. 



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

 6112, r? adult, coll. of E. A. and 0. Bangs. Collected Mar. 3, 1899, by 

 W. W. Brown, Jr. 



Specific characters. Much larger than M. semifusca 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. 



Color. Pileum dark grayish olive ; back and rump olive ; lores, supra-* 

 orbital and supra- auricular streak, orbital 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 bars; 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; 

 throat grayish white; breast grayish olive; belly and under tail-coverts 

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

 yellowish; bill wholly blackish. 



Measurements. Type, adult $ : Wing, 66.6; 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.' When collecting in the lowlands and among the smaller 

 mountains near Santa Marta, Mr. Brown took six examples of true M> 

 semifusca. 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 where neither M. semifusca nor M. montensis is found. This 



* Montensis, belonging to mountains.
