evident that much remains to be clone 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. Vespertilio sp., near V. serotinus. 



2 . 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 grovip, but I cannot at 

 present determine its exact relationship to V. turcomanus Eversm. 

 and V. mirza Fil. One thing is clear, liowever, that V. shiraziensis, 

 described in 1871 by Dobson, but afterwards referred by him, in 

 company with turcomanus and mirza, to V. serotinus, is a per- 

 fectly distinct species, readily distinguishable by its much greater 

 size. 



2. Vespertilio matschiei pellucens, subsp. n. 



S . 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 palei- in colour, the 

 upper surface uniformly pale buflfy, very slightly darker than 

 Ridgway's " cream-buff," which the under sui'face just matches. 

 Ears and membranes pale brownish, the hinder edges of the wings 

 white, and the posterior third of the inteifemoral transparent 

 white or colouidess. 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. 



Hah. as above. 



Type. Male. B.M. No. 5.10.4.4. Original number 16. Col- 

 lected 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 Fipistrellus kiMH, 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. PiPISTRELLUS KUHLT ISTatt. 



c? . 2, 5, 18, 20, 21. Ahwaz, Karun R. 220'. 



5 . 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
