Of this species Mr. Whitely unfortunately obtained only a 

 female specimen, so that I am unable to say whether the male 

 exhibits brighter colours. It is quite distinct from any 

 species known to me^ but apparently allied to E. cassini — itself 

 an aberrant species oi Eucometis [cf. Biol. Centr.-Am., Aves, 

 i. p. 307). If I am right in my conjecture as to the affinities 

 of E. oleaginea, the sexes would not differ materially in 

 coloration.
