on the lower breast very broad and continuous, and strongly tinged 

 with buffy ; abdomen and flanks immaculate buffy ; tibia? and under 

 wing-coverts black, barred with buffy white ; elongated feathers of 

 crest extensively white, the extreme base and terminal fourth black ; 

 "iris brown; feet dusky flesh-color; bill black," wing, 348; tail, 317; 

 bill, 44; tarsus, in. 



The female type agrees fairly well with the colored figure of the 

 supposed Cra.v incommoda in the Transactions of the Zoological So- 

 ciety of London, X, 1879, pi. 93, and with Mr. Ogilvie-Grant's later 

 description of the same specimen. As suggested by the latter author, 

 Sclater was doubtless wrong in referring this particular specimen to 

 his C. incommoda (=C pinima von Pelzeln), the type of which was 

 a very different looking bird, as may be seen by comparing the above 

 plate with the figure of the said type in the Transactions of the 

 Zoological Society of London, IX, 1875, pi. 49. The acquisition of a 

 second specimen showing these peculiarities,' coming from a definite 

 locality, would seem to prove this beyond a doubt. The present bird 

 differs from C. pinima in having much more white beneath, the barring 

 being carried up to the chin, while there is more white on the crest 

 also. The male gives the impression at first glance of being a minia- 

 ture of C. albcrti, but the female is of course very different from the 

 same sex of that form. 



The pair of birds upon which the above descriptions are based were 

 taken at Don Diego, January 26, 1914, in the heavy forest at the lower 

 edge of the foothills. The discovery of a second species of Crax in 

 this region is an event of unusual interest, the larger birds of the con- 

 tinent being relatively so much better known than the smaller forms.

The adult male of this fine curassow is a precise counterpart, so far 

 as color alone is concerned, of the Venezuelan C. danbentoni. The 

 bill, however, is differently shaped and colored, and the crest is rather 

 better developed. The females (which in this genus seem to furnish 

 better differential characters than the males) of the two forms are
