516 MESSRS. SCLATER AND SALVIN ON THE CRACID&. [June 9, 
The well-developed yellow caruncles at the base of the mandible 
distinguish this species from all its allies except C. daubentoni, in 
which the tail is broadly tipped with white. We have only seen 
one female of this species—in Mr. Lawrence’s collection. It agrees 
with Spix’s figure and description. The variation of the sexes in this 
bird corresponds to that which obtains in Craw carunculata, which 
has likewise conspicuous caruucles on the base of the bill. It the 
latter case, however, the caruncles are red instead of yellow.

This Curassow was confounded by the older authors with C. glo- 
bicera ; and it must always, perhaps, remain somewhat of an open 
question to which bird that name is more properly to be applied. 
Mr. Gray first recognized the existence of the two species, and in 
his ‘List of Gallinee’ gave the name daubentoni to the present 
bird, considering it to be that represented by Buffon and Dau- 
benton as the Hocco, Faisan de la Guiane in the ‘ Planches Enlu- 
minées.’ The two species are certainly close allies, the differences 
between them consisting in the present bird having caruncles at the 
base of the mandible, and white tips to the rectrices. The former 
character, however, is not very conspicuous, nor are these caruncles 
represented in the above-mentioned plate. 
We were for some time in doubt respecting the correct habitat of 
this species ; but during a recent examination of the examples of this 
group in the Paris Museum, Sclater found a specimen of it which 
had been transmitted from the vicinity of Caraccas by M. Levraud. 
This has indicated, what we before suspected, that the true patria 
of Crax daubentoni is the littoral of Venezuela and the northern 
portions of New Granada, where it takes the place of C. globicera 
on the north and C. alector on the south*. 
* Since this paper was written, the locality of this species has been further 
confirmed by the receipt by this Society of a living pair of this Crax from 
Tucacas, in Northern Venezuela (presented by James Wright, Esq., Sept. 29th). 
The bird described by Herr v. Pelzeln as the male of his Craw mikani seems 
to agree tolerably well with the female of this species.
