S92. A. ocheopus. Very common. 



The outermost tail feathers have as a rule a minute subterminal dark spot 

 on the outer web, and the same applies to the longest upper tail-coverts. 



893. A. HYPOLEUCUS. Very common. 



894. TotAjSTJS glottis. Very common. 



Average measurements of four specimens : wing 7'2 to 7*8 ; tail 32 to 

 3-4, tarsus 2"4 to 2"6 ; hill at front 2-1 to 22 inch. Most of the upper tail 

 coverts have dark cross bars, like the tail. There is a dusky streak from the 

 base of the upper mandible towards the eye, superseded by a pure white band. 

 Outer web of first minute primary and the shaft of the second, the longest 

 one, white. 



896. T. ptjscus. Very rare. 



The middle tail feathers have in a specimen distinct dark cross bars 

 along the margins of both webs. First long primary with a white shaft, all 

 are towards the margins of the inner webs minutely variegated with white 

 and dusky brown. 



897. T. calldeis. Eare. 



Wing 6-5,*:tail 25, tarsus 21, bill at front 1/8 inch. The first long 

 primary has a white shaft, and all are albescent on the margin of the inner 

 web ; lower tail coverts more or less streaked or spotted with dusky ; breast 

 cinereous, all feathers dark-shafted. 



898. Ht man topus lnteemeditis, Blyth. Very common. 



The birds with brownish back and scapulars, blackish hind-head, and with 

 a grey neck, are young. In some specimens the whole neck is white and the 

 occiput black. One adult male, shot in February, had the whole head white, 

 somewhat dusky behind the eye, on the occiput and a little lower below the 

 occiput pure black, then purely white, back and wing glossy greenish black, 

 rump white, tail ashy ; below entirely white. It is difficult to imagine what 

 the specific distinction should be between such a bird and, for instance, Gould's 

 figure of II. autumnalis, Hasselq. = melanopterus, Tern., in ' Birds of Europe.' 

 Gray (Hand-L, III, 47) quotes H. candidus, Bonn., as synonym of the Eu- 

 ropean autumnalis, reserving Blyth's name intermedins for the Indian bird, 

 but I do not think that the question as to the specific distinctness of the two 

 can be considered as settled. 



As regards size I found in Kachh specimens the following variations : 

 wing 9 to 9"7 ; tail 32 to 33, tarsus 425 to 53 ; bill 2 - 5 to 3 inch. 



899. Becuevieostea avocetta. Not common. 



In what appear to be rather young birds the dark upper coloration is 

 mixed with brown, and the short wing coverts are mostly pale brown. 

 An adult in full plumage, shot at the beginning of January, measures : wing 

 9'3, tail 35, tarsus 3"7, bill in a straight line from front to tip 3'35, this
