524 MESSRS. SCLATER AND SALVIN ON THE CRACIDE. [June 9, 
This species is included by Schomburgk in his ‘ Fauna of British 
Guiana ;’ but it is doubtful whether it really occurs so far north.

Our characters of this species are from one of the specimens ob- 
tained by Natterer at Ytararé, and named by Herr v. Pelzeln P. 
nigricapilla. It is not, however, Mr. Gray’s P. nigricapilla, but 
agrees perfectly with the specimen in the British Museum referred 
to P. jacucaca of Spix. At first we were inclined to accede to the 
latter determination, but have recently convinced ourselves that Spix’s 
figure and description of P.jacucaca are more satisfactorily appli- 
cable to another bird, of which we have given an account above, and 
which is distinguishable from the present species by its smaller size 
and by the well-defined white superciliary band, bordered (as Wagler 
expressly states) by black below. On the other hand, Spix’s figure 
and description of P. jacupeba are fairly applicable to the present 
bird, except as regards its larger size. But a second skin of an 
immature example in the collection of Salvin and Godman is consi- 
derably smaller than the Nattererian specimen above described, and 
seems to answer to Spix’s bird in every respect ; so that if we assume 
that Spix’s type was also not adult (which his figure would seem to 
indicate), we have a name provided for this species. 
We may remark that Mr. G. R. Gray agrees with us in re- 
ferring Spix’s P. jacupeba to the present species, though in our 
opinion he has wrongly associated it with P. jacucaca of the same 
author. 
Penelope jacupeba, as thus identified, is a fine large species of a 
general bronzy-green colour, which is somewhat tinged with rufescent 
on the rump and tail-coverts and still more so on the belly. The 
feathers of the whole top of the head are more or less edged with 
silvery grey, particularly on the front and over the eyes, but not so 
as to constitute a well-defined superciliary stripe; the ear-coverts are 
black. The characteristic white edgings which are found in all the 
group are well-defined in this species on the upper back, wing- 
coverts, neck, and breast. The outer primaries are attenuated as in 
other species of this genus; the fifth, sixth, and seventh are about 
equal and longest. The nearest ally of P. jacupeba is P. obscura,
