The following are the dimensions of a good adult female of this 

 species, sent by Mr. Mackenzie : — 



Head and body 246mm. ; tail 268; hindfoot 54 ; ear 34*5. 

 Skull, greatest length 55 (57 in an older specimen), condylo- 

 incisive length 52-5; zygomatic breadth 28; nasals 22; in- 

 terorbital breadth 8 ; breadth of brain case 21 ; palatilar length 

 25-8 ; palatal foramina 10-4; upper molar series 8'6. 

 Mr. Mackenzie's specimens were collected in the " Chin Hills, 

 50 miles west of Kindat ; altitude 5,000'." One example was also 

 obtained by Mr. S. F. Hopwood in 1913 at Kindat itself. Other- 

 wise the only representative of this species in the British Museum 

 had been that from Machi, Manipur, recorded in my list of the 

 Hume Collection (P. Z. S. 1886, p. 62). 



Ujjimys ferreocanus, Mill. 



This species has been full}'- described by Mr. Miller, with the 

 exception of its mammary formula, which I am now able to make 

 out to be 2 — 2=8, as in E". boiversi. 



The specimens before me come from Gunong Ijaa, Perak, 4.500', 

 and were presented by the Federated Malay States Museum through 

 the kindness of Mr. H. C. Kobinson.
