BIRDS FROM BRAZIL AND SOUTHERN VENEZUELA—FRIEDMANN 389 
the first specimen to be collected in Venezuela and is an addition to 
the avifauna of that country. The northern race MV. s. naso has been 
taken in northern Venezuela (Perij& and other localities). 
MICRASTUR MIRANDOLLEI (Schlegel): Mirandolle’s Harrier-Falcon 
Astur mirandollei Scatecen, Mus. Hist. Nat. Pays-Bas, vol. 2, 1862, Astures, 
p. 27 (Surinam). 
SPECIMEN COLLECTED 
1 ad. 3, Venezuela, Cerro Yapacana, Upper Orinoco, March 31, 1931. 
Even if Griscom and Greenway’s Panamanian race of this species, 
M. m. extimus, should prove to be valid (the material I have seen does 
not enable me to recognize it with any feeling of certainty), the 
present specimen would be of the typical subspecies. 
This is apparently a rather rare bird everywhere in all its vast 
range from Costa Rica to Peru and northern Brazil. The present 
specimen has the following dimensions: Wing 230, tail 198, culmen 
from cere 22.3, tarsus 73 mm. 
MICRASTUR RUFICOLEIS GILVICOLLIS (Vieillot): White-throated Harrier-Falcon 
Sparvius gilvicollis Vrsuutot, Nouv. Dict. Hist. Nat., vol. 10, 1817, p. 323 (no 
locality = Cayenne). 
SPECIMENS COLLECTED 
1 ad. 9, Brazil, Serra Imeri, near Salto do Hu4é, December 6, 1930. 
1 ad. &, Brazil, Sio Gabriel, Rio Negro, December 27, 1930. 
This gray-breasted race of its species occurs in the Guianas and 
southern Venezuela (Mount Auy4n-tepuf) southward to the Amazon 
Valley. It has not been recorded as yet from the Upper Orinoco or 
the Casiquiare; in fact, the only Venezuelan locality to date seems to 
be Mount Auy4n-tepui. 
The specimens collected are in fine, fresh plumage. 
DAPTRIUS ATER Vieillot: Yellow-throated Caracara 
Daptrius ater Vie1LLoT, Analyse d’une nouvelle ornithologie élémentaire, 1816, p. 
68 (Brazil). 
SPECIMEN COLLECTED 
lad. 9, Venezuela, Brazo Casiquiare, Playa de Candela, February 8, 1931. 
Found sparingly throughout the areas traversed by the expedition. 
The white basal area of one of the middle rectrices has a black 
blotch in it, apparently a type of individual variation common in 
this species as the majority of examples seen have one or more such 
spots, but no two birds are alike in this respect. 
Two other specimens from the Brazo Casiquiare, one taken at 
Cerro Guanari, February 4, and one at Cerro Mabinagui, February 
20, were saved as alcoholics.
