160 CONTRIBUTIONS TO THE ORNITHOLOGY OF INDIA. 



spot on the roof of the new shed as they had occupied in the 

 old, and this spot they were still occupying when I was at Port 

 Blair. It is remarkable the small amount of space that a very 

 large number of these birds will occupy ; they all cluster 

 together like a huge swarm of bees clinging to the bare boards 

 of the roof in a wonderful manner." 



The following are measurements taken in the flesh : — 

 Length, 3'75 to 4; expanse, 8*5 to 9'*12; wing, 3*82 to 4 ; 

 tail, 1'5 to 1*75 ; bill, from gape, 0'4 ; tarsus, 025 to 0*3.

This species is described, Stray Feathers, 1873, p. 294. "We 

 only procured one specimen, and I have nothing to add to what 

 I formerly said in regard to it, except that it is a considerably 

 larger bird than either unicolor, Jerdon, of the Nilghiris, or 

 the very closely allied, and barely separable race from the 

 Himalayas, of which also I have numerous examples. In no 

 one of the twenty odd specimens that I possess from the Nilghiris 

 and the Himalayas does the wing exceed 4 - 73... whereas in 

 innominata it is 5J) a inches. 



Independent o^ size (an innominata must weigh fully double 

 of what the Sikim or Nilghiri birds do), the present species 

 has a much more strongly marked black cap than any specimens 

 of the Indian birds ever exhibit. 



103 quat.— Collocalia spodiopygia, Peah f (20.) 



The original description of this species will be found, Stray 

 Feathers, 1873, p. 296. The following are the measurements 

 recorded in the flesh from a large series : — 



Length, 4-5 to 4-75 ; expanse, 106 to 11-3 ; wing, 4'5 to 4'75 ; 

 tail, from vent, 1*9 to 2 ; tarsus, 0'35 ; weight, not quite 05 oz. ; 

 the wings reach from 1 to 1'4 beyond the tip of the tail. 



The legs and feet are brownish pink ; the claws brown ; bill 

 black ; irides deep brown. 



The whole of the top of the head and back are a deep sooty 

 brown ; the rump is whity brown ; the feathers darker shafted ; 

 the wings, tail and upper tail coverts are blackish brown ; the 

 lower parts are a pale mouse brown ; the feathers of the abdomen 

 slightly dark shafted ; the sides of the neck are slightly darker 

 mouse brown, and so are the lores, in the centre of which in 

 the fresh bird, there is a small, triangular, very pale mouse 

 brown spot, scarcely recognizable in dry skins : the wing 

 lining and the tibial plumes are dark brown.
