^^hether this and the preceding bird are really distinct, or merely 

 local varieties of each other, it is difficult to say until a comparison 

 can be made between a series of speciraens of both sexes of each of 

 them. I am not eonfident that the birds described as their respect- 

 ive females are really such. Dr. Cabanis has kept the two birds 

 distinct, and I have followed his example — proposing to call the first 

 nigriventris, as niger is preoccupied . In fact the whole diflFerence 

 of this species from the preceding consists in its cinereous uropygium 

 and under plumage, and rather larger size. In the nigriventris the 

 belly is nearly as black as the back. Spix's figure seems most likę the 

 northern species. Swainson has well distinguished the two birds in 

 his ' Animals in Menageries,' pt. 2, under the names niger and spixi.
