thighs. It differs not only from these, but from almost all other 
members of the genus in the sexes being nearly alike. 
The patria of C. alector is Guiana and the adjoining districts of 
Amazonia up to the Rio Negro. In Upper Amazonia it is replaced 
by C. globulosa.

Azara clearly describes both sexes of this Curassow, which appears 
to be the sole representative of the group in Paraguay and the ad- 
jacent portion of the Brazilian province of Matto Grosso. 
It was, however, confounded with other species, or provided only 
with MS. names, till Mr. Gray descibed it in his list of Gallinze in 1867. 
As already remarked, the male of this species closely resembles 
the corresponding sex of C. alector; it is singular, therefore, that 
the females of the two species should be so very different. 
Our description of Craz sclateri is taken from Nattererian speci- 
mens in the collection of Salvin and Godman ; but we have compared 
them with Smithsonian skins collected by Capt. Page in Paraguay, 
and find them agree in every respect.
