Bill much shorter than head, slender-conoidal, gradually tapering to 

 the tip, the maxillary tomium with rather distinct subterminal notch. 

 Nostril small, in lower anterior portion of nasal fossae, narrowly oval 

 or subcuneate, overhung by broad membranous operculum. Rictal 

 bristles obvious but very weak and inconspicuous. Wing rather 

 short, nmch rounded (sixth primary longest, seventh and fifth but 

 little shorter, the ninth shorter than second); wing-tip about equal to 

 exposed culmen. Tail about as long as wing, decidedly rounded, the 

 rectrices narrow, with tips subacuminate. Tarsus more than one- 

 third as long as wing, its scutella rather distinct; middle toe with claw 

 decidedly shorter than tarsus; basal phalanx of middle toe united for 

 nearly its entire length to outer toe, for less than half its length to 

 inner toe. 



Coloration. — Plain olive-green above, the adult male with head and 

 neck slate-gray; beneath pale gray, becoming whitish medially. 



Nidijicidioii. — Unknown. 



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



This genus comes nearest Geothlypis., from which it differs decidedly 

 in the relatively weaker feet (with middle toe, without claw, decidedly 

 shorter than the commissure instead of equal to it or longer), obvious 

 rictal bristles, and very dissimilar style of coloration.
