Hab. Paraguay (Azara and Page); Brazil, prov. Mato Grosso (Natterer). 
Azara clearly describes both sexes of this Curassow, which appears to be the sole 
representative of the group in Paraguay and in the adjacent portion of the Brazilian 
province of Mato Grosso. It was, however, confounded with other species, or provided 
only with MS. names, until Mr. Gray described it in his List of Galline 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. 
We have received four or five living specimens in the Society’s collection which 
have been determined as “ Craw sclateri 2 ;” but I am a little doubtful whether they 
really belong to this species or to the dubious Crax pinima. One of these, spec. 6, 
received in 1863, is figured Plate XLV. It differs from the Nattererian specimen 
(figured Pl. XLIV. fig. 2) in being rather larger, in having rather narrower bands above, 
and in having the tail-feathers distinctly terminated with white instead of fulvous.
