ASSAM, SYLHET AND CACHAR. 349 



980.— Larus brunneicephalus, Jerd. 



Common about all the larger j heels of the Manipur valley, 

 including the Logtak lake, and at one moderate sized jheel 

 at Booree Bazar met with in a flock of at least ten thousand 

 individuals. This was on the 1st of March, and about half had 

 already assumed the dark hood. 



It seems quite incredible, but several people both at Booree 

 Bazar and at the Logtak declared that this species bred in 

 a marsh near the latter during the rainy season. I cannot 

 believe it. 



I observed this species in several of the rivers of Sylhet, 

 but have no record of its occurrence, nor did I observe it in 

 Cachar. It is found occasionally, but I believe very sparingly, 

 right up the Brahmaputra to Dibrugarh. 



[A few are occasionally seen on the Brahmaputra river, 

 and I have shot them at the mouth of the Dehing river. — 

 J. RC] 



Throughout British Burmah it is common along the entire 

 coast line and up the creeks and river estuaries inland 

 during the cold season. 



981.— Larus ridibundus, Lin. 



I only certainly saw one bird of this species in Manipur, 

 which I shot at the Logtak. Easy as it is to distinguish this 

 and the preceding at a glance, when in the hand by the 

 colours of the lower surfaces of the primaries, one cannot be 

 so sure of them seen at a distance on the wing. This was the 

 only one that I saw and recognized, and it being new to my 

 list shot, but amongst the thousands of Gulls that I saw and 

 passed as brunneicephalus, there mai/ have been a good many of 

 this species also. 



I have received this from close to Dibrugarh, and Godwin- 

 Austen records it from the junction of the Dunsiri and 

 Brahmaputra, and also apparently from somewhere in the 

 E. Naga hills, and this is all I know of its distribution in Assam, 

 Sylhet and Cachar. 



It has not. yet been recorded from any part of British 

 Burmah. 



983.— Sterna anglica, Mont, 



Also pretty common in suitable localities throughout the 

 Manipur basin. 



I observed this in Eastern Sylhet, and this is all I know of its 

 occurrence in Assam, Sylhet or Cachar.
