is quite similar, but with a shorter bill. The species is nearest iu 

 its relationships to C. virenticeps, but differs in the black maxilla; 

 the light base of the lower mandible ; the ashy frontal band (seen 

 indistinctly on the side of vertex) ; the much darker, and shorter 

 supra-ocular stripe ; the olive green of under parts instead of yellow, 

 and of much less extent ; the ashy region behind the eyes, etc.

and length of toes, shape of wings, tail, etc., and it is a question 

 whether they should not be united. The only difference is in a 

 rather less amount of curvature of culmen than in most species, and 

 a rather less depth of bill ; although in this respect G. nigrirostris 

 agrees exactly with Vireolanius. The legs are perhaps less stout. 

 The pattern of coloration is quite the same. The type differs most 

 from Cydorhis, and at the same time from the other species asso- 

 ciated with it in Vireolanius, in having the tail rather longer than 

 the wings, not shorter.
