This species was first described by Mr. Sclater from a specimen obtained by M. 
Boucard at Suchapam in the Mexican State of Oaxaca }, and it has since been traced to 
Guatemala and to the State of Panama, Colombia, and Western Ecuador, for birds 
from the latter country do not differ in any essential particular from the Mexican 
type. ‘Two female or young birds obtained by Mr. Nutting in Nicaragua agree fairly 
with a female from Western Ecuador, one of the types of O. ethiops, but which has 
since been united to O. fumereus*®. The bill in these birds is larger than in any male 
of O. funereus in our possession ; but, knowing how variable the bill is in 0. torridus, 
we do not attach much importance to this difference. Mr. Ridgway thinks the Nica- 
ragua birds hardly likely to belong to O. wthiops; but if, as we maintain, O. wthiops is 
the same as O. funereus, the probability of there being another species inserted in the 
middle of the range of that bird is very unlikely, and the fact can only be established 
after an examination of more specimens than are at present available. 
Our Guatemala birds were all obtained in the low-lying forest-country north of 
Coban in Vera Paz, where, however, the bird was not common. Mr. Nutting shot his 
examples in a patch of plantains and in some high marsh-grass, their habits being 
similar to those of Gwiraca concreta. 
AMAUROSPIZA.

This peculiar form has a general resemblance to Guwiraca, especially to the small 
G. parellina, but on closer examination the shape of the bill will show that there is no 
near relationship. 
The type A. concolor, so far as we yet know, is restricted to Costa Rica and the State 
of Panama; but the bird is so rare that little can be said about it. 
The bill is broad at the base, the culmen rather sharp and gradually curved from
