Genus CHLOROSPINGUS Cataanis. 



CMorospingus' Oabanis, Mus. Hein., i. May, 1851, 139. (Type, C. leucophrys 

 Cabanis, =vlrremon ophthalmicus Du Bus.) 



Small, plainly colored Tanagers, with small and not obviously hooked 

 nor toothed bill, the exposed culmen much less than two-thirds as long 

 as tarsus; colors plain olive or olive-green above (the pileum and hind- 

 neck sometimes gray, brown, or sooty), light-colored below, sometimes 

 with yellow on throat or chest; sometimes with white markings on sides 

 of head. 



Bill much shorter than head, subconical, deeper than broad at base, 

 where its width is decidedly less than length of gonys; exposed culmen 

 about half as long as tarsus or a little more, slightly convex; gonys a 

 little shorter than maxilla from nostril, less decidedly convex than cul- 

 men; maxillai-y tomium straight or faintly concave, slightly deflected 

 basally; mandibular tomium straight, slightly deflected basally. Nos- 

 tril exposed, small, longitudinallj' oval, with rather broad superior 

 membrane. Rictal bristles minute, hardly obvious. Wing rather 

 long (a little more than three to about three and one-third times as 

 long as the rather long tarsus), rounded (eighth to fifth primaries 

 longest, ninth shorter than fourth) ; primaries exceeding secondaries 

 by less than length of middle toe with claw. Tail shorter than wing 

 by less than half the length of the tarsus ( C. olivaceus and C. pileatus) 

 to nearly the length of the tarsus ( O. hypojphmm). Tarsus much longer 

 than middle toe with claw; outer claw reaching about to base of middle 

 claw, the inner slightly shorter; hind claw shorter than its digit — all 

 the claws well curved, sharp.
