BIEDS OF NORTH AND MIDDLE AMERICA. 213 



more compressed (its depth at frontal antiae decidedly greater than its 

 width at the same point), and with the sides of the maxilla finely 

 grooved" longitudinally. 



Bill rather large and strong, decidedly compressed, with culmen 

 strongly curved and tip of maxilla distinctly uncinate; exposed cul- 

 men decidedly more than half as long as tarsus; gonys equal to dis- 

 tance from nostril to tip of maxilla, strongly convex; maxillary 

 tomium straight, distinctly notched subterminally, the straight man- 

 dibular tomium with a slight corresponding notch, but tip of mandible 

 not distinctly produced, its point obtuse; depth of bill at frontal 

 antise slightly greater' than its width at same point; sides of maxilla 

 with several fine longitudinal grooves." Nostril exposed, longitudi- 

 nally ovate, in lower anterior portion of nasal fossae, its posterior end 

 scarcely touched by feathering of frontal antise, the latter bristle- 

 tipped, with the fine, curved bristles extending across nostrils. Rictal 

 bristles inconspicuous (apparently only two distinct). Wing moder- 

 ately long, rounded; tenth primary about half as long as ninth, the 

 latter slightly shorter than secondaries; seventh, sixth, and fifth px'i- 

 maries longest, the eighth shorter than fourth. Tail shorter than 

 wing (the difference less than length of tarsus), slightly rounded. 

 Tarsus less than one-third but more than one-fourth as long as wing, 

 decidedly longer than commissure, much longer than middle toe with 

 claw, distinctly scutellate anteriorly; outer toe distinctly longer than 

 inner, the latter (without claw) nearly or quite as long as hallux 

 (without claw), its claw not reaching to base of middle claw. 



Coloration. — Above plain olive, rather grayer on the head; beneath 

 plain yellowish buff, shaded with olive on chest. 



Range. — Island of Jamaica, Greater Antilles. (Monotypic.) 

 This genus is decidedly nearer to Yireo than to Oyclarhis; so nearly 

 like the former, in fact, that if Yireosylva and Lanwireo be not recog- 

 nized as genera Laletes certainly should not. 



LALETES OSBURNI Sclater. 



OSBURN'S VIREO. 



Adult male. — Pileum and hindneck plain brownish mouse gray or 

 grayish hair brown; rest of upper parts similar but more olive, the 

 rump inclining to grayish olive-green, the edges of remiges paler; 

 sides of head light olive-grayish; malar region, chin, and throat olive- 

 whitish; rest of under parts pale buffy yellow (between straw yellow 

 and naples yellow), the sides of chest strongly, the sides and flanks 

 faintly, shaded with olive; under wing-coverts primrose yellow; bill 

 dusky (bluish gray or grayish blue in life?) the terminal third (more 

 or less) pale brownish (in dried skins); leg.=; and feet light brown (in 



» This character possibly not constant.
