front with 11 or 12 scutes. The feathers from the front of 
the vertex to the nape are black, with two broad white bands 
in the middle. The neck and the head are black. The back 
and the wings are black_, with numerous transverse white 
lines. Some of these Hues are visible on the median rectrices, 
whilst others are uniform blacky all turning to white towards 
the point. The breast, the lateral parts of the body, and the 
legs are yellowish^ with broad, transverse, black bands ; the 
belly and the under tail-coverts are uniform yellowish. The 
wing measures 34, the tarsus 10 centim.

This is apparently based on a female of Crax pinima. The 
description of the plumage agrees almost exactly with that 
of specimen '^ c" in the British Museum Collection, described 
[cf. Cat. B. Brit. Mus. xxii. p. 447 (1893)] as '' a second and 
apparently less mature specimen. ^^ The groove on the bill is 
probably accidental and of little importance.

The birds from the Archipelago de las Perlas are separated 
from typical 0. cinereiceps (Gray) on account of their 
'^ very much smaller and weaker" foot and tarsus. The 
measurements given are as follows : —

This difference in size (which, as shown by our series, has 
no real existence) is, we venture to think, hardly sufficient 
to entitle the birds from the Archipelago de las Perlas to 
specific or even subspecific rank.
