 marked, in fact almost indistinguishable, dorsal stripes, but are 

 obviously not specifically separable.

These specimens'all belong to a group of Eats varying considerably 

 hi size, length of fur, and size of ears, but all agreeing in their 

 general proportions, and in the possession of a very large number of 

 mammae placed in a continuous series down the sides of the abdomen, 

 and varying in actual number from 16 to 24. To this group, 

 whether containing several valid species or, as I am inclined to 

 suspect, only a single variable and widely spread one, the following 

 appear to belong : — Mus concha, Sm., M. silaceus, Wagn., M. micro- 

 don, Peters, M. macrolepis, Sund., and probably several of the other 

 earlier described species. In the existing state of confusion in regard 

 to these species, I prefer to leave the present series of specimens 

 without a definite name.

 " Found in pairs in the gardens and plantations." — E. 



I have seen specimens referable to this species from almost every 

 part of the Ethiopian region, and among others the types of Mus 

 musculoides, Temm., and M. minimus, Peters, both of which names 

 must therefore give way to that of Smith. Specimen f, from 

 Tingasi, is considerably larger than usual, but is not apparently 

 specifically separable from the rest.

This rare species is a purely West-African one, but the genus ia 



* I take this opportunity of clearing up the liistory of another species of 

 Mits, which will, no doubt, be found to occur in Monbuttu, as Herr BohndorfF 

 obtained it at N'doruma, in the Niam-niam country, namely Mus allcni, Waterh. 

 (P. Z. S. 1837, p. 77), of which the type is a very young individual with its 

 teeth still uncut. This type is, however, unquestionably specifically identical 

 with the Niam-niam specimen, as also with two in spirit from Old Calabar (Dr. 

 J. A. Smith), and one skin from Angola (Mr. Monteiro), in the Natural History 

 Museum. There are also in the Berlin Museum several specimens of it obtained 

 on the Gold Coast by Drs. Buchholz and Eeiohenow, and the characters of these 

 specimens, and therefore of the adult M. alleni, have been pointed out by 

 Dr. Peters (MB. Ak. Berl. 1876, p. 479) under the erroneous name of M. ery- 

 ihrolcucus, Temm.
