yiew Central- Asiatic Birds, 491 



shown to me by ]\Ir. Gould, is completely identical with the 

 white-winged saxaul variety of P. leptorhynchus . 



Caprimulgus arenicolor, Sev. (falso C. isabellinus, Sev., 

 nee Temm.) . 



Closely allied to C. agyptius [C. isabellinus, Temm.), but 

 much larger, \\-2 inches longer, wing almost 1^ longer; bill, 

 however, smaller; wing less pointed, rem. 2>3>1; colour 

 somewhat more greyish sandy, but all markings nearly the 

 same ; sexual difference trifling, the adult male has one outer- 

 most tail-feather on each side broadly tipped with white, the 

 female with isabelline ; the young male individually varying 

 in the colour of these tips, which he has sometimes white, 

 like the old male, sometimes isabelline, like the female, and 

 sometimes of both colours (that is, white shaded with isa- 

 belline). 



Length 10^-11 inches, expanse 24-26*6, wing 8*4, tail 5*3, 

 bill 0'42. C. (egyptius has a total length of 9 inches, wing 7, 

 bill of 0'6, and is more rufous isabelline, rem. 2>1>3. 



Further particulars on the geographical range and habits 

 of this bird will be given by me in ' The Ibis,' in Mr. Dres- 

 ser's extracts from my ^ Turkestan skii Jevotnyi' (Turkestan 

 vertebrate animals). Here I remark that it is common only 

 on the lower Oxus, rarer on the Syr and in the south part of 

 the east Caspian shore ; everywhere a summer bird. 



Phasianus semitorquatus, Sev., new species ? or variety ? 



A near relative to P. mongolicus, the male differing in 

 some important particulars ; the female less so, and may 

 easily be confounded with the female of that species. 



Male. General colour a In-ight, moderately intense rufous 

 chestnut, with metallic gloss, as in P. mongolicus, and quite 

 similar small, black, metallic green-glossed feather-tips, which 

 are also, in the same way, differently shaped on different parts 

 of the body — very narrow, on some feathers disappearing, 

 edges with a central small black blotch at the end of the shaft 

 on back and breast, broader black ends on the sides. 



But on closer examination all the feathers of the head and 

 neck are not quite so metallic green as those of P. mongolicus ;
