several specimens in the Calcutta bazaar and identified them. 

 He then, on examining the specimens of Fuligula nyroca collected 

 by Mr. Blyth, found that one of them, which had been in the 

 Asiatic Society's Museum since 1842, was a female of N. baeri. I

 has again been obtained commonly in Calcutta, so it is probable 

 that this species has hitherto been confounded with the nearly 

 allied N. ferruginea.

 Nepal in the Himalayas, and the neighbourhood of Attock r 

 Gurgaon near Delhi, and Karachi in the plains of India, and even 

 Bombay (Jour. Bom. 1ST. H. Soc. ii, p. 97). Col. McMaster is of 

 opinion that he saw several birds of this species near Berharnpore 

 in the Northern Circars. The Scaup is chiefly a bird of the north
