Hal). 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 Gallinse in 1867. 



As already remarked, the male of this species closely resembles the con'esponding 

 sex of C. alector ; it is singular, therefore, that the females of the two species should be 

 so very difi'erent. 



We have received four or five living specimens in the Society's collection which 

 have been determined as " Crax sclateri ? ; " but I am a little doubtful Whether they 

 really belong to this species or to the dubious Crax pinima. One of these, spec, b, 

 received in 1863, is figured Plate XLV. It diflfers from the Nattererian specimen 

 (figured PI. 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.
