Type.—KAxxlt skin. B. M. No. 19. 3. 1. 1. Original number 304. 

 Collected by Captain Kingston, I. M.S. 



This bat, which is named in honour of its first captor, presents 

 an intermediate stage in size between the small E. innesi of Egypt 

 and the U. s. turcomamts of Persia. E. shiraziensis, Dobs, of S. W. 

 Persia is again larger still. 



2. Eptesicus walli, sp. n. 



A small pale coloured species allied to E. pellucens and matschiei. 



Size rather larger than in E. ]jellucens. 



General colour, so far as can be observed on a spirit specimen, 

 very much as in that species, with sandy buffy back, biiffy whitish 

 undersurface, and translucent membranes, pale brown for the most 

 part, then becoming whitish along the hinder edge of the wings and 

 on the posterior third of the interfemoral. Forearms, tibias, and 

 tail, dark brown. 



Ears rather short, triangular, the front edge nearly straight, the 

 tip narrowly rounded off, almost pointed, the outer edge slightly 

 convex ; outer basal lobe little developed. Tragus of medium 

 height, its outer margin slightly convex, with scarcely a trace of 

 basal lobule, tip rounded, inner margin straight. Wings to the 

 base of the toes. Wing membranes near the body, and interfemoral 

 numerously studded with warts, similar to those in Bhinopterus, 

 and there are a certain number of warts on the forearms and tibias. 

 A narrow postcalcareal lobule present. Middle third of tail with 

 an elongated thickening about half an inch in length either of a 

 glandular or a fat-storing nature ; a similar structure seems to be 

 present in E. pellucens, so far as can be judged from skins. 



Skull closely similar to that of E. pellucens, but markedly larger 

 and heavier in all dimensions. Upper inner incisors thick, 

 unicuspid, but worn at the point in the type. 



Dimensions of type, measured on the spirit specimen : — 



Fore arm, 40 mm. Head and body, 55 mm.; tail, 42 ; ear, 13 ; 

 tragus on inner edge, 4-3: third finger, metacarpus, 38 ; first phalanx, 

 11-7 ; lower leg and foot (c. u.), 23-3. 



Skull, condylo-basal length, 13-7; basi-sinual length, 11 ; zygo- 

 matic breadth 10*4; interorbital breadth, 5; breadth of braincase, 

 7; bi-eadth aci'oss canines, 4-8; across m\ 6, 5; front of canines 

 to back of m"^, 5-3 ; front of p* to back of m^, 3-7. 



Habitat. — Mesopotania. Type from Basra. 



y^jje.— Adult female in spirits, B. M. No. 19.3.1.2. Original 

 number M. 17. Collected by Lieut.-Col. F. Wall, I.M.S. 



This species is most nearly allied to the bat I described as 

 Vespertilio matschiei pellucens, but its skull and dentition are so 

 much larger and heavier that it should evidently be separated. The
