Dormice of the Genera Eliomys and Glis. 227 



The type of E. pallidas is no. 98. 10. 6. 6 of the British 

 Museum Collection. 



Of E. quercinus the British Museum possesses specimens 

 from France, Miirren (Switzerland), Bavaria, Thiiringen 

 (Tyrol, Austria), Dalmatia, North-west and South Spain, and 

 Portugal ; but a specimen from Tunis appears to be referable 

 to E. melanurus, Wagner. 



Specimens from Tangier, Morocco, agree in size with 

 E. mumbyanus (Pomel), first described from Algeria, and I 

 therefore provisionally refer them to that species, although 

 the skins at present at my disposal are too old and faded to 

 enable me to gain a clear idea of their original colour. This 

 would appear, however, to be a slightly paler animal than 

 E. quercinus, although not nearly so pale as E. pallidas. 

 The difference in size between the two species will be appre- 

 ciated by a glance at the series of cranial measurements (in 

 millim.) given below. The skull of E. quercinus is very 

 much larger than that of E. mumbyanus, and, in addition, the 

 brain-case is flatter, the nasal region broader and more solid, 

 and the nasals themselves more compressed posteriorly.

* There is also in the British Museum Collection a skull (no. 94. 3. 12. 2) 

 of E. mumbijanus presented by Dr. V. L. Seoane and labelled as from 

 Cabanas, North-west Spain, but I fear there must be some mistake about 

 this locality.
