Cotyle obsoleta

Cotyle (Ptyonoprogne) obsoleta, Cab.

91bis. :- Murray's Vertebrate Zoology of Sind, p. 104; Hume; Stray Feathers, Vol. I, p. 1.

Length, 5.25 to 5.6 ; expanse, 12.25 to 13 ; wing, 4.4 to 4.75 ; tail, 1.8.

Bill black ; legs and feet horny-brown.

The whole upper surface a very pale greyish earthy-brown, very much paler than the same parts in P. rupestris or C. sinensis ; the quills only slightly darker, yet sufficiently so to contrast pretty markedly with the scapulars, back, rump, and upper tail-coverts ; the lateral tail-feathers, all but the external feather on each side, with a large oval white spot on the inner web, as in rupestris, and with dark shafts and a darker tint on the web near the shaft, as in that latter species; lower surface as in rupestris, but much paler ; the whole of the chin, throat, breast, and abdomen being white with only a faint fulvous or rufous tinge, and the wing-lining and lower tail coverts, which in rupestris are a decided dark-brown, are in this species the same pale earthy grey-brown as the upper surface.

Mr. Hume states that the Pallid Crag Martin occurs along the streams that issue from the bare stony hills that divide Sind from Kelat, and also that it is common off the rocky headland of Manora, at the mouth of the Kurrachee Harbour. It is not recorded from any other portion of the district.
