397. Hypolais obsoleta.
The Desert Tree-Warbler.
Salicaria obsoleta. Severtz. Turkest. Jevotn. pp. 66, 129 (1873): id. S. F. iii, p. 426. Hypolais obsoleta (Sev.): Seebohm, Cat. B. M. v, p. 86.
Coloration. Resembles H. rama, but the whole upper plumage is a pale sandy brown.
Length about 5 ; tail 2 ; wing 2.4 to 2.6 ; tarsus .75; bill from gape -65. The second primary terminates between the sixth and seventh ; the distance from the tip of the first primary to the tip of the wing is 1.3 to 1.5; the secondaries fall short of the tip of the wing by .45 to .6.
Distribution. Seebohm possesses a skin which was obtained in Sind, but this I have not been able to examine, owing to its having been sent to Russia. We can, however, have no better authority than Seebohm for the identification of this bird. It is a rare species. It is supposed to summer in the desert portions of Turkestan, and to winter in Sind. It has occurred at Fao in the Persian Gulf.
