Show 520 MR. OLDFIELD THOMAS ON [Dec. 12, evident that much remains to be done in this area, and I would draw the attention of other Indian sportsmen to Col. Bailward s success, with the hope that when coming home to England they may follow his admirable example in working Persia by the way. 1. V e sp er t il io sp., near V. serotinus. $ . 27. Mala-i-Mir, 70 mi. N.E. of Ahwaz. 4300'. This Bat, of which Mr. Witherby also obtained examples near Telespid, is a pale form of the Serotine group, but I cannot at present determine its exact relationship to V. turcomanus Eversm. and V. mirza Fil. One thing is clear, however, that V. shiraziensis, described in 1871 by Dobson, but afterwards referred by him, in company with turcomanus and mirza, to V. serotinus, is a perfectly distinct species, readily distinguishable by its much greater size. 2. Y esp er t il io m a t sch ie i p e l lu c e n s, subsp. n. c? . 14, 15, 16, 17, 19. Ahwaz, Karun R., S.W. Persia. 220'. " Common in the town." Closely similar to the species recently described as V. matschiei*, from Aden, but slightly larger, and markedly paler in colour, the upper surface uniformly pale buffy, very slightly darker than Ridgway's " cream-buff," which the under surface just matches. Ears and membranes pale brownish, the hinder edges of the wings white, and the posterior third of the interfemoral transparent white or colourless. In true matschiei the membranes are dark opaque brown throughout. Dimensions of the type :- Forearm 35• 7 mm. Head and body (in flesh) 45 ; tail 43 ; ear 13. Skull, greatest length 13'2. Hab. as above. Type. Male. B.M. No. 5.10.4.4. Original number 16. Collected 28 Mar., 1905. This beautiful little Bat is readily distinguishable from all others by its uniform pale colour, the hairs being pale to their roots. In the pale form of Pipistrellus kuhlii, found in company with it, the bases of the hairs are dark, even though the tips are light. The peculiar translucent character of the posterior third of the interfemoral is also very unusual. 3. P ip istr e l lu s kuh lt N a t t . . 2, 5, 18, 20, 21. Ahwaz, Karun R. 220'. $ . 11. Dizful, near Ahwaz. These specimens vary a good deal in colour, some being nearly as light as the darker examples of the last species. But the darkest are far lighter than South European specimens, and no doubt * Thos. Ann. Mag. N. H. (7) xvi. p. 573 (1905). |
