RECENTLY-DESCRIBED SPECIES. 407 



and lower tail-coverts almost pure white, with only the faintest 

 creamy tinge ; the rest of the lower parts a dull rufous fawn, 

 somewhat rufescent on the breast, sides, and flanks. 



The tail is much rounded, the lateral tail-feathers being 

 from 0*37 to 0*4 shorter than the central ones. The specimens 

 I possess were procured in December, in the Kumaon Terai, 

 not far from Kaladingii. — Ibis, 1871, p. 36. 



Caprimulgus Unwini, Hume. 



This species has the upper three-fourths of the tarsus feathered 

 in front. In both sexes the two outer tail feathers on each side 

 are tipped with white ; but the tippings are about 1*55 and 1*0 

 broad in the male on the outer and penultimate feathers, respec- 

 tively, and only about 0*75 and 0*44 in the female ; and in 

 the latter sex the white is less pure. Both sexes have a white 

 spot on the inner webs of the first three, and a corresponding 

 one on the outer webs of the second and third primaries ; but 

 here again, while the spots on the inner webs of the male are 

 about one inch broad, those of the female are about half that size. 

 This species therefore differs in its leading characteristics 

 from all our Indian goatsuckers. In general appearance it most 

 resembles C. Kelaarti ; but as regards the white on the tail and 

 the extent of the feathering of the tarsus, it belongs to a differ- 

 ent group from this species and C. indicus. The best description 

 I can give of its plumage is, that it is an excessively pale and 

 grey version of C. indicus, and that, while (with the exception 

 of the difference in the size of the white markings on tail and 

 wings) the sexes closely resemble each other, the under tail- 

 coverts of the male are a uniform rufous buff, while those of 

 the female are somewhat paler and are very distinctly barred 

 with narrow bars more than a quarter of an inch apart. 



The dimensions of a female measured in the flesh were : — 

 Length, 10*25 ; expause, 19*25 ; tail, 4*75 ; wing, 6*95. 

 Wings when closed reached to within one inch of the end of 

 tail. 



The male (not measured in the flesh) is slightly larger, and 

 has the wing 7*2 long. — Ibis, 1871, p. 406. 



Trochalopteron simile, Hume. 



Exactly resembles T. variegatnm, which it replaces in the far 

 North-West, except that the grey portions of the primaries and 

 tail-feathers are pure French-grey entirely untinged with yellow, 

 olive, or orange. — Ibis, 1871, p. 408. 



[I quote this as it is often referred to, but it seems likely that 

 the grey type was the one originally described, and that it is the 

 yellow tinged race that should be named.]
