ASTUR. — ACCIPITER. 227 



proved the two species to be identical beyond dispute. I have 

 come to the conclusion, therefore, that the type of U. JanUnei in 

 the Xorwich Maseuni and the specimen from British Guiana 

 in the British Museum are botli females of Astar poUogaster 

 (Temm.). and that the specimen of ^J. poUogaster in the National 

 collection is a male. The distribution of tlie species, as far as is 

 kno^svu at present, is Guiana, Eastern Brazil, and Paraguay.
