70 Messrs. J. C. Melvill a7id J. H. Ponsonby on 



to ochraceous-buff on muzzle and cheeks, and with a faint 

 brownish wash nlong middle of back ; underparts between 

 buff and creara-bufi', slightly darkened by the slaty under- 

 colour, the line of demarcation along sides of body rather 

 well defined ; throat and median region of chest white to base 

 of hairs ; whiskers blackish ; upper lip whitish buff except in 

 region of muzzle ; feet dull greyish buff ; tail obscurely 

 bicolor, similar to back above, though rather conspicuously 

 darkened by a brownish suffusion through terminal third, 

 light buffy below, though not so pale as belly. 



Skull and teeth. — The skull resembles that of Muscardinus 

 avellanarius, except that the audital bullae are circular in 

 outline and much smaller, owing chiefly to the absence of the 

 inflated region between paroccipital process and bullae proper. 

 This inflation is always present in M. avellanarius, destroying 

 the circular outline of the bullae when viewed from the side. 

 Teeth as in M. avellanarius. 



Measurements. — Head and body 80 mm. ; tail-vertebrse 66 ; 

 hind foot 17 ; ear from meatus 10 ; ear from crown (dry) 5*8. 

 Skull : condylo-basal length 21-2 ; zygomatic breadth IH ; 

 mastoid breadth 10*6; interorbital breadth 3-4; nasal (along 

 median suture) 7 ; diastema 5*6 ; mandible 12*4 ; upper 

 tooth-row (alveoli) 4'4 ; lower tooth-row (alveoli) 4. 



Specimen examined. — The type. 



HemarJcs. — In all respects, except for the small circular 

 audital bullae, this species so exactly resembles Muscardinus 

 avellanarius that I can detect no other characters by which it 

 may be recognized. While the Turkish dormouse is repre- 

 sented by the type specimen only, the series of skulls of the 

 European animals is sufficient to show that the outline of the 

 bullae is constant enough to be of much importance in distin- 

 guishing betueen closely related forms. 



X. — A Survey of the Species and Varieties of Pupa, 

 Droparnaud (Jaminia, Risso), occurring in South Africa.

[Plates I. & II.] 



When Mr. Henry C. Burnup visited England recently, 

 we pointed out to him that several so-called species of 

 Pupa appeared to be insufficiently defined, suggesting that he 

 would, perhaps, feel inclined, on his return to S. Africa, to
