 black."— Wing 63, 59| ; tail 35, 34 ; bill 9A, mm. 



The adult 6 is rather deeper yellow on the forehead and uuder-parts than 

 a series from the Ucayali (Peru), Maipnres (Orinoco), and Bogota collections, but 

 agrees with them in dimensions, size of the bill, and in the extent of yellow on 

 the forehead. The type of E. melanura from Manaos differs from all the other 

 specimens examined by its smaller size, much smaller bill, and smaller yellow 

 frontal patch. Additional examples from the typical locality are required to 

 confirm the constancy of these divergencies. 



E. melanura is easily distinguishable from E. riolucea lirliteiisteinii (cfr. mipni, 

 p. 6) by its much larger size, entirely black tail without any white markings, and 

 by having the yellow of the forehead extended over the anterior portion of the 

 crown.

The specimen agrees perfectly with the type from Yuracares and with the 

 three S 6 ad. collected by Natterer near S. Vicente, Villa Maria and Villa Bella, 

 in Mattogrosso.* As pointed out by Dr. J. A. Allen,t this species is quite distinct 

 from E. crassirostris, of Colombia, Venezuela, etc. The five adult S 6 before me 

 differ from a very large series of the latter species by having the nnder-snrfaee 

 and the patch on the forehead much darker, deep cadmium yellow (instead of 

 chrome yellow), the back, wings, and sides of the head purple (instead of steel blue), 

 and by their much shorter and quite differently shaped bill.
