62 Mr. O. Thomas on new Forms of 



This pretty species seems only nearly related to the 

 D. famulus of Aden, the other species of this region all 

 having comparatively small bulla?. Its partially hairy soles 

 seem peculiar to itself and to the species next described. 



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

 place about 200 miles east of the Dead Sea, an example 

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

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

 from 1). dasyurus, Wagn., from the neighbouring coast of 

 the Red Sea, of which we have two examples from Sinai,- 

 presented by the Giza Zoological Gardens. Nehring himself 

 gives no valid reasons for the distinction, merely saying that 

 the species " appears to be new, although allied to D. dasyurus, 

 which is so insufficiently described that nothing can be done 

 without examination of the type." Both dasyurus and 

 dasyuroides 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), campestris, to which the type has been hitherto 

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

 not unlike the deepest and richest specimens of Apodemus 

 sylvaticus. Sides clearer and lighter, approaching " sayal- 

 brown." Under surface, as usual, pure white. Face with 

 scarcely perceptible supraorbital light patches ; post-auricular 

 white patches present. Ears with their proectote pro- 

 minently 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 the 

 second and posterior pairs thinly clothed with fine hairs, very 

 much as in D. arabium. Tail buffy brown above, darkening 

 terminally, whitish below ; the tip probably not heavily 

 tufted, but this part is imperfect in the type. 



Skull considerably smaller and narrower than that of 

 D. campestris, apparently like that of D. arabium } but the 

 bullae have been lost in the type. 



Measurements of the type : — 



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

 22-5 ; ear 15. 



Skull : greatest length 28; zygomatic breadth 15; nasals
