BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 507 
include all these specimens, except the Mand4os bird, are not separable 
from australis of Argentina, Bolivia, and southern Brazil. This is not 
corroborated by comparative material at hand; the southern birds 
(australis) are paler above. On the basis of geography it would be 
surprising if southern Venezuela was inhabited by the same form as 
Argentina, etc., since the typical race intervenes between the two 
areas. 
Recently Zimmer and Phelps (Amer. Mus. Nov., No. 1312, 1946, 
p. 11) have described a more brownish-backed race, M.f. brunnescens, 
from the Apure River, and along the Orinoco from Altagracia to 
Puerto Ayacucho and across westward to Villavicencio. According to 
this all the above birds except the one from Mandos would be brun- 
nescens, but I cannot see the characters of this race constantly enough 
in this material to feel that they are really brunnescens and not ferox 
varying in that direction. Two of the five birds are browner than 
the other three.

In view of what Zimmer has written (Amer. Mus. Nov., No. 994, 
1938, pp. 19-20) about the possible validity of coalez I have compared 
the present birds with the type of coalei and with examples from 
northern Venezuela and from Santa Marta, Colombia. There are 
no constant differences between them, and so the current allocation of 
coalei in the synonymy of typical tuberculifer holds.
