The adnlt males agree with others from S. Paulo, Rio de Janeiro and Miuas 

 Geraes, and have like those from Cayenne and Venezuela (which we may consider 

 as typical) the throat extensively deep black, and the general colour is the same 

 shade of blue. Brazilian birds, however, are as a rule rather larger than those from 

 more northern localities, though this is not quite constant. 



Skins from Pern, Bolivia and Mattogrosso (Chapada) differ at a glance by 

 having the throat-patch smaller and much duller, more greenish black. This 

 is I>. cat/ana glaucogidaris Berl. & Stolzm. Some of the Chapada birds slightly 

 point towards D. c. cayana.

These birds, as well as two adult males obtained by Natterer, which I have 

 likewise before me, agree perfectly with a series from Bahia as far as coloration 

 is concerned, but average slightly larger. 



E. chlorotica, with its geographic forms, is involved in great confusion, and 

 requires careful revision ; but 1 have neither time nor suificient material to enter 

 into the question.
