The type specimen of O. johnstoni is evidently undergoing its 

 autumn increase of fur, for the line buff tips of the new hairs are 

 to be distinguished halfway down in the fur among the old ones. 

 The hairs are growing up evenly all over the body, and not in 

 patches. On the other hand, in a specimen of G. murinas in the 

 spring moult (Rustenberg, Transvaal, September 1895 ; coll. 

 H. P. Thomasset) the moult is taking place iu patches, so that 

 we have in these animals (so far as the evidence of two specimens 

 is to be trusted) a similar method of change to what we see in 

 some of our own northern animals, e. r/. the Squirrel, in which 

 the spring moult is equally done in patches, while the autumn 

 growth takes place uniformly all over the body.

This interesting Gerbille is no doubt in a general way allied to 

 Lataste's subgenus Tutera, to which G. leucogaster belongs, but the 

 marked differeiice between its incisors and those of the other 

 subgenera seems to render advisable a special group for its 

 reception. The unusual breadth of the incisors, their slight bevel, 

 and their flatness (the two faint grooves being scarcely perceptible) 

 render them quite unlike those of any other Gerbille. The type 

 of the species was described from Qua Mpala, Marungu.

Some of the specimens from Nyasaland previously recorded by 

 me as D. mesomelas are also D. pumilio, hitherto (but, as I now 

 think, erroneously) united with D, mesomelas.
