ZOOLOGICAL EESIJLTS OF THE EUWENZOEI EXPEDITION". 



a considerable proportion of longer hairs (25-30 mm.) black with buff tips. Hands 

 and feet ochraceous buff; tail sparsely clothed with short adpressed hairs; dark 

 above, pale below. 



Skull as in ffi. b. unyori, but interorbital area widening evenly backwards, not 

 parallel-sided ; anterior margin of anteorbital plate concave as in ffi". bacchante. 



Dimensions of the type (measured in the flesh) : — 



Head and body 150 mm. ; tail 180 ; hind foot 30 ; ear 20. 



Skull : greatest length 38 ; basilar length 31 ; zygomatic breadth 17-5 ; diastema 

 10"5 ; upper molar series 6*9. 



Type. Adult male, B.M. no. 6.7.1.139. Original number 70. Collected 2nd 

 February, 1906, by Mr. E. E. Dent. 



[Numerous on Euwenzori up to the lower limit of the forest-zone at 6500 ft. 

 They were also plentiful among the native clearings in the Congo Forest, feeding on 

 the rice- and millet-crops, where the natives catch and eat them. — R. B. W.] 



Hitherto all forms in the genus (Enomys (except the two small species (E. dembeensis 

 and ffi. harringtoni) from N.E. Africa have been classed as subspecies of (E. hypoxanthus. 

 After examining the considerable material now available Ave are of opinion that, 

 at least, the West Coast forms (ffi. hypoxanthus and ffi. anchietm) with their larger 

 (especially broader) teeth should be separated from the smaller-toothed Eastern ones 

 (ffi. bacchante, (E. unyori, and (E. editus). 



The following is a comparative table of the principal measurements (in mm.) of 

 the five forms mentioned : — 



The known forms of the GLnomys hypoxanthus group may be arranged in a key, as 

 follows : — 



A. Rather larger. Head and body 170-180 mm.; hind foot about 32 j 

 greatest length of skull 40. Upper molars larger, markedly broader. 

 (W. Africa.) 

 «i. General colour darker, suffusion chestnut. Tail equal in length to 



head and body. (Gaboon &c.) hypoxanthus Puch.
