The males, while fully corroborating the distinctness of E. laniirostri.-i, differ 

 from the type and Natterer's Mattogrosso examples by having the chin-angle 

 narrowly bordered with blackish. The females agree, in coloration, with E. 

 crassirostris Scl., from Colombia, Venezuela, etc., but have a much thicker, wider 

 bill. Two (Nos. 3 and 173) have, on the npper surface here and there, especially 

 on the occiput, a distinct slaty or oily gloss. The range of E. /. la/ii/rosfr/s is 

 restricted to the Rio Madeira (Humaytha, Calama, etc.). Western Mattogrosso 

 (Villa Maria, Sao Vicente, Villa Bella, Abrilongo, Chapada), and Northern Bolivia 

 (Yuracares). In Central Peru it is replaced by the nearly allied E. la/iiirostr/s 

 peruviana Berl. &. Sfolzm.f 



[38. Euphonia melauura Scl. 



Cf. Nuv. Zuol. xiv. p. 317 (Borba). 



Right bank : Borba (Hoffmanns). Not secured on the present occasion. 



E. melanura differs from the preceding species by its even (not emarginate) and 

 entirely black tail. In E. laniirostris the outermost rectrix (and sometimes also 

 the succeeding one) shows a large white patch on the inner web. 



E. melanura is widely distributed in Upper Amazonia.]
