P. marail, though resembling the previous species, is readily di- 
stinguishable by its smaller size and darker colour, and by the absence 
of white markings on the upper portion of the back. Its range 
seems strictly confined to the Guianas. 
It must always remain doubtful what species Merrem’s Penelope 
Jacupema was intended for; but his description seems more ap- 
plicable to the present bird than to P. cristata, to which it is some- 
times referred. 
3. PENELOPE GREEYI.

Penelope cristata, Pelzeln, Orn. Bras. p. 280 (2). 
Similis precedenti, sed crassitie minore, et colore supra viridi 
magis purpurascente, forsan diversa: long. tota 24, ale 11,

This seems to be a small form of the preceding species. Besides the 
type specimen described by Mr. Gray, we have only seen two other 
examples, which are now living in the Society’s Gardens. 
If Herr v. Pelzeln’s P. cristata be not referable to the present 
species it must belong to one which we have not yet come across.

Of this Guan we have only yet met with three specimens, now 
living in the Society’s Gardens. They were purchased of a dealer 
in Liverpool on the 9th of February last, and were in very bad 
plumage when received, though now gradually recovering. We have 
little hesitation in referring them to Spix’s species, when explained 
by Wagler’s diagnosis, which we have adopted in the absence of spe- 
cimens for complete examination. 
The ‘‘ Eyebrowed Guan”’ of the Knowsley Menagerie is referable 
to this species, though coloured too rufescent in tint. We have exa- 
mined the typical specimen now in the Derby Museum at Liverpool.
