tail-coverts; length 19.75-24.00, wing 7.50-8.50, tail

eastern Mexico, from Vera Cruz north to lower Rio 
Grande Valley (both sides). 
311. O. vetula maccalli (Barrp). Chachalaca.!

O. vetula pallidiventris Rrpa@w. (subsp. nov.). 
“Yucatan Chachalaca.

O. poliocephala Wace. Gray-necked Chachalaca.® 
&. Quills chestnut. 
Otherwise very similar to O. plumbeiceps, but much browner above. 
O. cinereiceps Gray. Costa Rican Chachalaca.4 
1TIt is possible that this may be the true O. vetula of WacuER (Penelope vetula Wact., Isis, 1830, 1112), 
which seems to agree exactly in color with O. maccalli ; but the size is much smaller, the length being given 
as 18 inches, the tail 9.70. The locality is given as simply “ Mexico,” and it may be that a fourth local race, to 
which Wagler’s name is strictly applicable, may exist in some portion of Mexico specimens from which have 
not come under my observation.
