3S2 Messrs. 0. Thomas and R. C. Wroughton on 



postero-interual cusp quite as plainly as either venustus or 

 rutilans. 



Dimensions of the type (taken on the skin) : — 



Head and body 135 mm. ; tail 160 ; hind foot 21 ; ear 15. 



Skull : greatest length 29 ; basilar length 23 ; greatest 

 breadth 15 ; nasals 10 ; interorbital breadth 5*6 ; brain-case 

 breadth 12-7; palatilar length 12-5; diastema 8; palatal 

 foramina G"5 ; upper molar series 5*5. 



Mr. Alexander has recorded the body-dimensions of 

 another specimen (skull missing), taken the same day and 

 obviously older, as follows : — Head and body 145 mm. ; 

 tail 200 ; hind foot 35 (? 25) ; ear 15. These measure- 

 ments agree fairly closely, but for the shorter ear, with those 

 of rutilans and venicstus. 



Bab. Angu, Welle River. 



Type. Young adult female. Original number 87. Col- 

 lected by Capt. G. B. Gosling on the 30th January, 1906. 



This species, though undoubtedly closely allied to venustus 

 and rutilans, and, except for the smaller ears and some small 

 differences of fur, texture, and colour, not easy to distinguish 

 externally, is readily separable by the smaller skull and 

 teeth. 



Lophuromys major, sp. n. 



A large Lophuromys about the size of Ansorgei, de Wint., 

 but with the colouring of aquilus, True. 



General colour above a very dark brown, minutely speckled 

 ■with cinnamon, merging without any sharply defined line 

 into " vinaceous cinnamon " below. 



Hair of the back &c. rather short (8 mm.), shorter than in 

 Ansorgei, rather harsher than in aquilus and much more so 

 than in Ansorgei ; basal ^ or § of each hair cinnamon, the 

 remainder black, with a subterminal cinnamon ring ; on the 

 belly the hairs of one colour from base to tip. Crown of head 

 and face coloured like the back ; ears and tail looking almost 

 naked to the unaided eye, but covered with minute black 

 hairs through which the skin-colour shows. Chin, throat, 

 and inner side of limbs coloured like the belly, but in a 

 rather darker shade. 



Skull markedly larger than in any other species of Lophu- 

 romys except Ansorgei, with which it closely agrees in size 

 and shape. Teeth as in Ansorgei. 



Dimensions (those of the body measured in the flesh) : — 



Head and body 145 mm. ; tail 72; hind foot 25; ear 15. 



Skull : palatilar length 15 ; brain-case breadth 13 ; inter-
