FAMILY GLIEID^E. 

 GEN. GEAPHIUEUS. 



Graphiunts, F. CUVIER et GEOFFROY, Hist. Nat. Mam., livr. 60 

 (1829). Type G. ocularis. 



Tail very bushy and somewhat distichous. 



Dentition. i. 1/1, c. 0/0, p.m. 1/1, m. 3/3 = 20; incisors not 

 grooved ; molars rooted, exceedingly small, especially the premolar, 

 which is about half the width of the other teeth ; the crowns of the 

 molars are hollowed out, the rims being formed of a ridge of enamel ; 

 scarcely any traces of infoldings can be distinguished. 



This genus is confined to the Ethiopian region ; the smaller species 

 were formerly placed in the genus Eliomys, of which the Garden 

 Dormouse of Europe (E. melananis) is the type, but they are now 

 considered to be more appropriately assigned to the present genus 

 originally formed for the reception of the large Grey Dormouse of 

 South Africa. 



In addition to the species below described some half-dozen have 

 been recorded from other parts of Africa.
