depression of the general line of the cranium.

Otomys typus fortior, Thos. Ann. & Ma?, Nat. Hist, (7) vol. xviii. 

 p. 302 (1906). 



Larger than the preceding species with a much flatter 

 skull, the interorbital region showing very little of the 

 characteristic arched appearance seen in the other members 

 of this group; m^ with 9 laminjs. 



In colour this species most nearly resembles angoniensis, 

 the yellowish suffusion so evident in pei'civali, and to a certain 

 extent in typus, is here almost absent ; dorsal surface a 

 uniform brown, lined with buff. Light markings around 

 eyes and ears absent. Backs of hands and feet dirty brown. 

 Under parts slate-grey washed with buff. 



Skull, as stated above, without any marked elevation of 

 the interorbital region. Incisors and molars large and broad ; 

 m^ with 9 laminaj, the last very small. 



Dimensions of the type : — 



Head and body 182 mm, ; tail 97 ; hind foot 30 ; ear 2G, 



Skull : greatest length 39 ; basilar length 32'2 ; zygo- 

 matic breadth 19*8 ; width of brain-case 16*7 ; greatest 

 width across nasals 7'2 ; depth from highest point of orbit to 

 alveolar border at front of m^ 11*8 ; palatilar length 19*1 ; 

 length of upper molar series from front alveolar border to 

 buck of wi^ 11-3. 



J/ah. Charada, Kaffa. Altitude 6000 feet. 



Ti/2^e. Adult female. B.M. no. 6. 11. 1. 29. 



This form was described by Thomas as a race of typus ; 

 on account of its cranial characters and the occurrence of 

 9 laminae in m^ it is here considered as a distinct species.
