BIRDS OF TENASSERIM. 489 



served it in the Tonghoo district. We have not as yet met with 

 it anywhere in Tenasserim proper. 



954. — Casarca rutila, Pall. 



This was seen by Davison at an immense swamp at Kedai- 

 Keglay, between Thatone and the Sittang, and also on Kolan 

 Island in the Mergui Archipelago ; but these were the only 

 occasions on which he saw them during four years' constant 

 work in all parts of the province. 



955. — Casarca leucoptem, Blyth. 



JBlyth says, B. of B., p. 165, that this species inhabits the 

 valleys of the great rivers from the Megna at least to the 

 Tenasserim. 



Davison has examined the valleys of the Sittang, the Salween, 

 the Attaran, the Gyne, the Houngthraw, the Tavoy, and the 

 Tenasserim, but he has never yet either seen or heard of this 

 species. If it does occur in Tenasserim, it can only be as an 

 extremely rare straggler. 



959. — Anas pacilorhyncha, Gm. 



Blyth says, B. of B., p. 165, that this occurs in Tenasserim, 

 but we have never met with it, nor have we been able to hear 

 of its occurrence, which I consequently hold to be doubtful. 



962. — Dafila acuta, Lin. 



Davison examined a freshly-killed specimen (unfortunately 

 half plucked) of this species in Moulmein, which had been shot 

 on the lakes about 19 miles out on the Amherst road. This 

 was in November. 



964.— Querquedula crecca, Lin. (l). 



Kedai-Keglay. 



Rare, only observed in the plains between the Sittang and 

 the Salween. 



965.— Querquedula circia, Lin. (6). 



(Tonghoo, Earns.) Kedai-Keglay. 



Only observed in the tracts between the Salween and the 

 Sittang and west of that river, and in the neighbourhood of 

 Moulmein, where Captain Dodd informs us that he has often 

 shot it.
