20 couple at Huswali, but this was after an unusually heavy 

 flood. I heard, too, of a Snipe having been picked up in the 

 compound of the N. I. mess in the Crater itself.

Larus, sp. inc., Barnes, Ibis, 1893, p. 175. 



This is the undetermined Gull of Barnes's list. It was 

 fairly common at Aden in February and April 1895, and I 

 brought specimens to the British Museum.

This species undoubtedly does visit Aden, though the 

 specimen recorded (Ibis, 1886, p. 23) was caught in a 

 butterfly-net when going ashore at Bunder Marriyah, on the 

 Somali coast.
