Cercomela melanura, Rupp.
493. :- Jerdon's Birds of India, Vol. II, p. 133.
THE BLACK-TAILED ROCKCHAT.
Length, 6; wing, 3.12; tail, 2.35 ; tarsus, 0.88. Bill blackish; legs black.
Of an uniform ashy-brown tint above, paler on the throat and breast, and passing to whitish below ; under tail-coverts white ; the tail and upper coverts black.
It is extremely uncertain whether this bird occurs in India or not, but Jerdon says, that " among the drawings of Sir A. Burnes is one of a saxicoline bird, procured in Sind, which Mr. Blyth identifies with Ruppell's bird, which is a native of N. E. Africa and Arabia"
As no other observer has since procured it from thence, it must have been an isolated straggler, that had wandered far from its usual haunts.
