542 NOTES ON COSTA RICAN BIRDS 



Picolaptes gracilis, sp. 



Sp. Char. — Nearest /'. lacrymiger Br. in coloration of the unaer part* 

 but upper surface somewbai as in P. falcinellus (Light.), and bill mac 

 smaller than in either. 



A d ult female (type, No. 115039, U.S. Nat. Mns., Monte Kedondo,Cost 

 Rica, July 25, 1887 ; A. Alfaro).— Pilenin, hind neck, back, scapular* 

 and wing-coverts light sepia-brown or bistre, but this broken, excep 

 on lower back, scapulars, and wing-coverts, with broad guttate mesia 

 streaks of pale buff, bordered with blackish, the latter almost forming th 

 ground-color on top of the head. Tertials, greater part of secondarie 

 and primaries (except basally, where more olivaceous), rump, uppo 

 tail-coverts, and tail plain chestnut or hazel, the terminal portion o 

 inner webs of primaries dusky. Sides of head and neck pale buffi 

 streaked with brownish black or dusky brown; chiu plain pale buffy 

 throat similar, but feathers narrowly bordered with dusky, producing, 

 squamate appearance. Ground color of other under parts hair-brown 

 but this relieved by broad mesial streaks of pale buff, each marginei 

 laterally by a narrower but very distinct blackish streak; these mark 

 ings, especially the blackish streaks, becoming nearly obsolete on belly 

 Hanks, and under tail coverts. Bill blackish, with basal half of lowe: 

 mandible whitish; legs and feet dusky; "iris black." Length (skin) 

 7.10; wing, 3.55; tail, 3.G0 ; the lateral feathers 1.05 shorter; exposed 

 culmen, .81; tarsus, .85. 



The only Central American species at all closely related to tne presen 

 one is P. compressus Cab., which comes rather close in the coloration o 

 the upper parts, which, however, are decidedly more rufesceut; but tin 

 lower parts are very decidedly different, the lighter markings being ii 

 P. gracilis much paler (buffy whitish instead of deep buff), and "tin 

 blackish streaks much broader; besides, P. compressus has the bil 

 much longer, and light browu instead of mainly blackish. 



Sclerurus canigularis, sp. nov 



Sp. Char.— Similar to 8. albogularis Swains., but much darker, th< 

 throat ash-gray (whitish on chiu), the back, etc., deep Vandyke brown 

 and lower parts dark slaty tinged with brown. 



Type, No. 115038, U. S. Nat. Mus., male adult, Turrialba, Costa Kica 

 August, 1886 ; J. J. Cooper. (Described iu detail on a subsequent page 

 ot these Proceedings.) 



Lophornis adorabilis Salv. 



A very perfect adult male, obtained by Mr. Jose C. Zeledon at SaD 

 Jose, October 7, 1880 (No. 1000, Nat. Mus. Costa Kica). "Bill coralline, 

 tip black." 



Cheetura bnmneitorques Lakh.
