Jerrugineis ; mento tegminibusque caudcs inferioribus sordide 



albis. 

 Rostrum pedesque nigri. Longitudo (cauda inclusa) 18| — 20 



unc, cauda 2|. Whistling Teal. 

 This bird, of which Colonel Sykes has many specimens, is iden- 

 tical with a bird in the British Museum, from Africa j one in 

 the Zoological Society, from Bengal j and one in the India 

 House, from Java. In the whole of these, the lunules on the 

 breast, neck, and upper part of the back, and the strong black 

 short mane of the Anas arcuata are wanting. It is also larger 

 than that bird, and Colonel Sykes is therefore led to believe 

 this to be a distinct species, although strongly resembling it. 

 Gregarious, and abundant in Dukhun. Sexes alike in plumage. 

 These birds are characterized by a very peculiar whistle when 

 disturbed, by a proportionate length of intestine one third 

 shorter than that of any other species of the Anatidce, and by 

 the inferior larynx being dilated into two oblong chambers, 

 placed rather in front of, than lateral to the trachea. 



Genus Querquedula , Ray. Teal. 



221. Querquedula Circia, Steph., 12. 143. Anas Circia, Linn., 1.204. 



Sarcelle oVete, BufF., Ois. 9. 268. PI. Enl. 946. Gargany 



Teal. 

 Length, inclusive of tail, 16| to 17 j inches; tail 3 to 3 T V inches. 

 Female the smaller bird, and quite dissimilar in plumage. Iden- 

 tical with British specimens. Gregarious. In addition to simi- 

 lar contents of the gizzard in other species, rice in the husk 

 was found. 



222. Querquedula Crecca, Steph., 12. 146. Anas Crecca, Linn., 1.204. 



Petite Sarcelle, Buff., Ois. 9. 265. PI. Enl. 947. Common 



Teal. 

 Identical with male and female British specimens. Length, in- 

 clusive of tail, 15| to 16 inches; tail 3 inches. Water-weed 

 and gravel in the stomach. Colonel Sykes has in his possession 

 specimens (male and female) resembling the female of Querq. 

 Crecca; but in which the proportional length of the intestinal 

 canal differs so much from that of Querq. Crecca ^330 to 1, 

 and 5*57 to 1), that he is induced to believe they may belong 

 to a distinct species. It will be observed that the proportional 

 length of the intestine (5*57 to 1 ) closely approximates to that 

 of a widely-different bird, the carrion-devouring Percnopterus. 



Genus Fuligula, Steph. Pochard. 



223. Fuligula rufina, Steph., 12. 188. Anas rufina, Pall. Le Ca- 



nard Siffleur huppe, Buff, Ois. 9. 282. PI. Enl. 928. Red- 

 headed Pochard. 

 Length, inclusive of tail, 25 inches ; tail 3J inches. Digastric 

 muscle remarkably thick. Rare in Dukhun. Vegetable mat- 

 ters and gravel in the stomach. 



22 1. Fuligula . Ash-brown Pochard with white speculum. 



This bird has a considerable resemblance to the female of Ful. ru-
