Gra)*'s type of pu/cfiellus is in the Museum collection (a 

 stuffed specimen), but the skull has only now become avail- 

 able. It shows that the tyj)e was a quite young animal. 

 There is no exact record of locality beyond West Africa, but 

 another specimen, presented to the Museum by Mr. E. R. 

 Alston, from " Fantee,^'' agrees closely with Gray's type in all 

 essential characters, and is a somewhat older individual. 

 From these I venture to deduce the following dimensions for 

 jnilchellus (the dimensions in italics are from actual measure- 

 xiient on the type) : — 



Head and body 115 mm. ; tail 110 ; hind foot 27 ; ear 14. 



tSkull : greatest length 30; zygomatic breadth 11^) molars 5. 



The specimens sent by Mr. Kemp are very much larger 

 and stouter all round and their colouring more rufous, especially 

 on the rump, and the tail is longer than the head and body. 

 The following are dimensions recorded by Air. Kemp: — 



Head and body 1^0 mm. ; tail 140 ; hind foot 30; ear 19. 



{Skull: greatest length 32 ; basilar length 24'5 : zygomatic 

 breadth 15 ; upper tooth-row 5"4 j buJlte 5.
