50 Records of the Indian Museum. [Yol. XV, 



examined). Nasals decidedly broader than in L. d. dayanus, much 

 produced posteriorly on their outer margins, not truncate as in L. d. 

 craspedotis. 



Colouration. — Upper surface very pale salmon-bufE, the hairs of the 

 back and upper flanks usually with short black tips. Base of the fur 

 pale smoky-grey, lighter on the flanks, succeeded by a broad clearly 

 defined band of black, most pronounced on the back, and then by a 

 salmon-buff subterminal band and a short black tip, often absent. Chest 

 and nape and anterior flanks pale isabelline-buff, the hind limbs more 

 salmon-buff. Chin, inner surface of limbs and under surface of tail pure 

 white. Upper surface of tail deep clear black. 



Ears : external half of upper surface clad with fine sa)mon-buff hau', 

 slightly intermixed with black, the proximal two-thirds of the upper edge 

 fringed with coarse yellowish-buff hairs finely edged with black at the 

 tips ; internal half of upper surface almost pure silvery-white with a 

 large patch of black at the tip ; this patch edged with buff, the 

 remainder with pure white. Ears internally thinly clad with buffy- 

 white, deeper in tint towards the tips. 



Measurements. — Hindfoot (dry) 120 mm. ; ear 110 mm. 



Skull. — Larger than that of L. d. craspedotis or than an equally aged 

 skull of L. d. dayanus. Palatal foramina longer and relatively narrower 

 than in either of the allied forms ; nasals broad and parallel-sided, much 

 produced posteriorly on their outer margins ; cranial region broad. 

 Teeth as in L. d. dayanus. Bullae slightly smaller than in L. d. dayanus, 

 very much smaller than in L. d. craspedotis. 



Measurements of the typical skull : greatest length 87 (81-2)^ ; basal 

 length 67 (63-5) ; greatest length of nasals 39 (31) ; palatal foramina 23 

 (20) ; upper molar series (alveolar) 16 (14-5). 



Remarks. — The affinities of this hare, so far as can be judged from 

 descriptions and from the available specimens in the Indian Museum, 

 are almost certainly with the Indian races, of which L. dayanus is the 

 best known, rather than with Palaearctic forms. It does not seem in any 

 way connected with forms from Arabia proper and from Muscat, which 

 have been described by Hemprich and Ehrenburg and by Thomas.
