62 Mr. O. Tlionias on ncic Forms of 



This pretty species seems only nearly lelated to the 

 />. fiiinulus of Aden, the other species of this region all 

 having comparatively small bulU\3. Its partially hairy soles 

 soom |>ccnli;ir to itself and to tlie species next desciibed. 



On the same expedition Mr. Carrnthers also collected, at a 

 place about 2'>0 miles east of the Dead Sen, an example 

 almost topotypical of, and certainly referable to, D.dasyuroides, 

 Nehring*. But I fail to see any reason for its distinction 

 from 1). dasj/iirus, Wagn., from the neighbouring coast of 

 the Red S'a, of wliicli we have two exam|)le.s from 8inai, 

 presented by the Giza Zoological Gardens. Nehring iiimself 

 gives no valid reasons lor the distinction, merely saying that 

 the species " appears to be new, although allied to I), daayurus^ 

 which is so insufficiently described that nothing can be done 

 without examination of the type." Both dasijunis and 

 diisyuroides have bullae of the comparatively small size usual 

 in the genus. 



Dipodillus hilda, sp. n. 



A Moroccan species with partially hairy soles. 



Size and general appearance very much as in the browner 

 forms of I), campesb-is, to which the tj^pe has been hitherto 

 referred. General colour above russet- or cinnamon-brown, 

 not unlike the deepest and richest specimens of Apodemus 

 si/Ivaticiis. Sides clearer and lighter, a|)])roacIiing " sayal- 

 brown." Under surface, as usual, j)ure white. Face with 

 scarcel}' p'^rceptible supraorbital light patches ; post-auricular 

 white patches present. Ears with their proectote pro- 

 minentlj' blackish, contrasting markedly with the general 

 colour of the head; hairs on metentote white. Hands and 

 feet white. Soles with six pads,* the region between tiie 

 second and j)osterior pairs thinly clothed with fine hairs, very 

 much as in D. arahium. Tail biifFy brown above, darkening 

 terminall}', whitish below ; the tip probably not heavily 

 tufted, but this ))art is imperfect in the type. 



Skull consiilerably smaller and narrower than that or 

 D. compestris, apparently like that of D. arahium, but the 

 bullae have been lost in the type. 



Measurements of the type : — 



Tail (imperfect) more than 100 mm. ; hind foot (wet) 

 22-5; (ar 15. 



Skull : greatest length 2%; zygomatic breadth 15; nasals
