67. Busarellus nigricoUis (Lath ). 



[The young specimen obtained by Mr. Nutting is in plumage so dif- 

 ferent from that described by me in Bull. U. S. Geol. and Geog. Survey 

 Terr. (vol. ii, No. 2, p. 143), that a detailed description seems desirable. 



Young (No. 87440, La Palma, Costa Eica, April 11, 1882, C. C. Nut- 

 ting) : Head and neck creamy buff", deeper posteriori}^ and becoming 

 nearly- white on frontlet, lores, and chin, each feather marked with a 

 distinct lanceolate mesial streak of dusky, except on tbe whitish parts 

 named above, where the feathers have merely narrow, dusky shaft- 

 streaks. Lower parts, rump, and upper tail-coverts rusty ochraceous ; 

 lower part of throat crossed by a somewhat crescentic patch or bar of 

 dull black, and breast crossed by a similar but broader oand of chest- 

 nut-rufous, each feather having a central dusky, pointed spot ; feathers 

 of jugulum and lower part of breast marked with distinct mesial streaks 



*Tlie name Antenor, which was proposed, by nie in 1873 for tbis geuus, is, as I have 

 recently discovered, preoccupied in Conchology (Montfort, 1808); another name 

 being therefore necessary, I have selected the one given above in preference to a new 

 one, on account of its being already on record, in Hist. N. Am. Birds, vol. iii, 1874, 

 p. 250, where, by an oversight in correcting j) roof- sheets, " Fat-ahuleo" is allowed to 

 stand instead of Antenor. — R. R.
