the plate, and the hitter, again, is opposite the extreme front 

 edge of m^). Front edge of zygomatic plate slanted, little 

 curved, not subangularly projected forward. Palatal foramina 

 shorter, barely equalling the length of the molar series. 



Molars not so simple and Epiniys-Wko, as in Hyhomys, but 

 more tending to the character of those of Mylomys as com- 

 pared to Pelomys *, although not so extreme. 



The middle cusp of each lamina is, as in Mylomys, highly 

 developed, beak-like, directed backwards, the laminte are 

 similarly curved round, and complicated by the development 

 of connecting-ridges between the laminae, notably between 

 the first and second laminae of w\ 



Type. Typomys trivirgaius {Mas trivirgatus, Temm.). 

 The character of the molars of this animal is one common 

 to several African genera — e. g., Mylomys, CEnomys, and 

 DesmomySj — but as to whether it is an independent develop- 

 ment in each case or shows any community of origin 1 am 

 not at present prepared to express an opinio:). Ilybomys, 

 otherwise not widely different from Typomys, has (piite 

 normally constructed molars. 



8ix specimens of Typomys trimrgatus were obtained by 

 Mr. Buntino- in Liberia.
