HAMOPHILA.—CHAM ZOSPIZA. 399 
There can be no doubt that this species is a close ally of H. humeralis, with which 
it agrees in general facies; but it has a black throat instead of a white one, and the 
sides of the neck and the whole chest are ashy instead of black, thus rendering it easy 
of recognition. 
Mr. Ridgway placed this species in Amphispiza, but the long rounded tail and very 
short wings associate it with the section of Hemophila containing H. ruficauda and its 
allies, rather than with Amphispiza. 
Its previous position was in Zonotrichia, of which it formed a decidedly abnormal 
member. 
H. mystacalis has long been known as a bird of Southern Mexico, where it inhabits 
the mountainous regions of Oaxaca and the neighbourhood of Tehuacan. It is a 
resident species, Sumichrast having observed it in August, but of its habits we have no 
records. 
CHAM AOSPIZA. 
Chameospiza, Sclater, P. Z.S. 1858, p. 304. 
This genus was founded by Mr. Sclater upon a single species, C. torquata, which has 
been treated as a Pipilo by DuBus, and as a Buarremon by Lawrence. The principal 
point laid stress upon by Mr. Sclater is the great size and strength of the feet and the 
length of the hind claw, which exceed those of any Pipilo or Buarremon. With the 
latter genus Chamcospiza has very strong affinities, and we much doubt the propriety 
of placing it here amongst the Finches instead of near Buarremon with the Tanagers. 
But we defer to the usual practice in this case. 
The bill in Chameospiza is strong but somewhat elongated, with a notch near the 
extremity of the tomia; the latter is slightly undulating, with an ill-defined angle on 
the proximal side of the middle; the nostrils are large, at the anterior lower end of the 
nasal fossa, with a membrane above them; the rictal bristles are short but stout. The 
wing is much rounded, the third, fourth, and fifth quills being the longest ; the second 
equals the seventh, and the first falls short of the wing tip by more than half an inch. 
The tail is long and rounded. The tarsi and toes are very strong, the middle toe and 
claw being equal to the tarsus; the claw of the hind toe is longer than the toe itself, 
strong and moderately curved.
