Whatever the Meleagris cristata of Linnzeus may have been in- 
tended for, there seems to be little donbt that the Penelope cristata 
of Latham, Temminck, and Wagler refers to this species, which is 
readily known by its large size (almost equal to that of P. purpu- 
rascens) and the deep chestnut of the lower back and belly. 
Mr. Gray considers P. jacuacu of Spix referable to the present 
species; but it seems to us that it is much more reasonable to refer 
Spix’s figure and description to the next, similar but smaller species, 
which is from the very country where Spix discovered it. 
‘We have examined specimens of this bird from Costa Rica, Pa- 
nama, and New Granada; we have not yet met with Guianan exam- 
ples, and it is possible that they may belong to the next species.

This Guan most nearly resembles the large species we have called 
P. cristata, but is distinguishable by its smaller size, by the lower 
back being only slightly rufescent instead of deep chestnut, by the 
well-defined white edgings of the feathers of the upper back (which’ 
are almost, if not quite, absent in P. cristata), and by the rufescent 
colour below extending over the lower surface of the breast, though 
with a more subdued tint. 
Our description is taken from one of Natterer’s Amazonian speci- 
mens, which agrees with the bird called P. doliviana in the British 
Museum, and with Mr. Bartlett’s skin from Yurimaguas. 
There is a living example of this bird now in the Society’s 
Gardens. ‘
