with regard to Le<igada which Fi/rotm/s (Vol. XX, p. 996) does to 

 JEpimys. A closer examination of the series of Leggada obtained by 

 Mr. Crump in Cutch, showed that these too (which are undoubt- 

 edly L. sadhu) had the same formation of the skull and could not 

 therefore be a local race oi flatyihrix. Amongst these iindoubted 

 specimens of L. sadhu, however^ are some which, while showing 

 the same mammary formula, are smaller in size and have the 

 peculiar skull formation of sadhu less well developed. 

 I propose to describe them as : — 



LeGGADA CmDERELLAy sp. lliOV, 



The Guteh Spiny Mouse. 



A Leggada of the sadhu type with a mammary formula of 4-2^1 2^ 

 but of smaller size, and having the mesopterygoid fossa narrowed 

 anteriorly but the posterior nares not, or scarcely, closed over. 



Size slightly smaller than in sadhu. General colouring differing 

 but little from that of that species, viz., drab grey above and pure 

 white below. 



Skull markedly smaller, with the mesopterygoid fossa narrowed 

 anteriorly but the posterior nares not, or scarcely, roofed in. 



Dimensions of the type (recorded by the Collector). — Head and 

 body 85 ; tail broken, but judging from proportions in other- 

 specimens about 67 ; hind foot 16 y ear 13. 



;S'A:ztZ^.— Condylo-basal length 22 (25); basilar length 19 (21); 

 zygomatic breadth 6 (7*5); nasals 9'5 (10); diastema 6 (7*5); 

 upper molar series 4 (4<-5^. 



Habitat. — Cutch State. (Type from Bhuj.) 



Type.—0\^ female. B. M, No. 12-1-9-12. Original No. 321, 

 Collected, 27th July 1911^ by Mr. C. A. Crump aioid presented 

 to the National Collection by the Bombay Natural History 

 Society. 



Mr. Crump obtained 8 or 9 specimens, some of them at the same 

 places in which he took L. sadhu. 



The peculiar formation of the mesopterygoid region in the 

 skulls of sadJiu and cind&rella, though it has not been recorded in an 

 Indian Leggada, is well known in some African forms, where it 

 varies in definition in various species.
