1834.] Catalogue of Birds in the Dukhun. 647 



tail, 12$ to 14 inches ; tail 3 to 3f inches. Sexes exactly alike. Monogamous, 

 Vegetable matter and gravel found in the stomach. These birds, when wound- 

 ed, dive, and on returning to the surface show only the bill above water, keep- 

 ing the body below at pleasure. 



Genus Tadorna, Leach. 



215. Tadorna rut il a, Steph., 12. 71. Anas Casarca, Linn., App. 3. 224. Shieldrake. 

 Bruhmuny Duck of Europeans in Dukhun. 



Irides yellowish brown. Length, inclusive of tail, male 28 inches, female 25 to 26 

 inches ; tail 5$ inches. For the most part of the year these birds are in pairs, but 

 on the Nerbudda river in Guzerat, Colonel Sykes has seen them congregated in 

 hundreds in April. Found in the stomachs of many birds, grass seeds and ve- 

 getable matters only. The female is destitute of the black ring round the neck 

 ornamenting the male. The intestinal canal twice the proportional length of 

 that of the Plectropterus. 



Genus Anas, Auct. 



216. Anas strepera, Linn., 1. 200. Chipeuu, Buff., PI. Enl. 953. Chestnut lesser 

 wing-covert Duck. 



Males identical with specimens in the British Museum from Kent. No females 

 for comparison. Length, inclusive of tail, male 24 to 25 inches, female 22 

 inches; tail 4 inches. Numerous in Dukhun. Gregarious. A tape-Worm was 

 found protruding through the coat of the intestine in one bird, without affecting 

 its health or flesh. 



Genus Rhynchaspis, Leach, MSS. 



217. Rhynchaspis virescens, Leach, MSS. Anas clypeata, Linn., 1. 200. Souchet, 

 Buff., Ois. 9. 191. PI. Enl. 971. 972. Black-headed shoveler. 



Identical with British specimens of the common Shoveler ; but differing from the 

 description of that bird in Shaw. Irides yellowish brown. Length, inclusive of 

 tail, 20 to 21 inches; tail 4 inches. Grass seeds, vegetable matters, pulse-like 

 seeds, and gravel found in the stomach. Gregarious. The intestinal canal is 

 more than seven times as long as the body, neck and bill included ; and in this 

 particular is not approached within nearly two-sevenths by any other bird of the 

 order Natatores. 



Genus Mareca, Steph. Wigeon. 



218. Mareca pcecilorhyncha, Steph., 12. 134. Anas jxxcilorhyncha, Gmel., 1. 535. 

 Spotted-billed Duck, Lath. 



Irides red fuscous brown. Length, inclusive of tail, 22 to 25 inches ; tail 4 to 4$ 

 inches. Sexes alike in plumage. Grass seeds, vegetable matters, and small 

 stones found in the gizzard. Colonel Sykes's birds identical with a specimen in 

 the British Museum, from the Himalayan mountains. The spot at the end of 

 the bill invariably yellow, but in books it is stated to be white. The di- 

 gastric muscle thicker than the diameter of the cavity of the gizzard. Colonel 

 Sykes does not consider this species a true Mareca. 

 219 Mareca fistularis, Steph., 12. 131. Anas Penelope, Linn., 1. 202. Canard Siff- 

 leur, Buff., Ois. 9, 169. PI. Enl. 825. Wigeon. 



Irides red fuscous brown. Length, inclusive of tail, 19 to 20 inches (male), 18$ to 

 19 inches (females); tail 3$ to 3| inches. Gregarious. Absolutely identical 

 with specimens from Devonshire. Contents of the gizzard as in the preceding 

 species. 



220. Mareca Awsuree. Mar. nigrescenti-brunnea ; plumarum scapularium dorsi- 

 que apicibus Jtavescenti-brunneis ; teg minibus alarum minoribus caudceque superi~ 

 oribus saturate castaneis ; vertice linedque cervicali fuscis ; capite, collo,pectorequc 

 pallide favescenti-brunneis, ventre uropygioque saturatioribus ferruyineis ; mento 

 tegminibusque caudee inferioribus sordide albis. 



Rostrum pedesqne nigri. Longitudo (cauda inclusa) 18$ — 20 unc, caudee 2$. 

 Whistling Teal. 



This bird, of which Colonel Sykes has many specimens, is identical with a bird in 

 the British Museum, from Africa ; one in the Zoological Society, from Bengal ; 

 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 Anati- 

 dce, and by the inferior larynx being dilated into two oblong chambers, placed ra- 

 ther in front of, than lateral to the trachea. 



Genus Querquedula, Ray. Teal. 



221. Querquedula Circia, Steph., 12. 143. Anas Circia, Linn., 1. 204. Sarcelle d'ete, 

 Buff., Ois. 9. 268. PI. Enl. 946. Gargany Teal.
