Genus Mus, Linn. 



* Mus BOWERSii, n. s. Plate XVII. 



Uniformly grizzled blackish-brown above, paler on the sides and the fronts of 

 the legs ; pale yellow below and on the feet and on the tip of the tail, distinctly 

 defined from the darker colour. Head rather long; muzzle long and pointed. 

 Ears large, ovate, very sparsely covered with short brown hairs. The tail exceeds 

 the length of the body and head and is finely ringed, three rings in one-tenth of an 

 inch, with short brown hairs between the rings. The feet are strong, and the hind 

 foot is long ; the claws are short and strong, and the pads are well developed as in 

 rats partially arboreal in their habits.

The hairs are rather coarse, but consist of two kinds ; first, there are pale 

 yellowish- grey and fine wavy hairs intermixed among the second kind which con- 

 stitutes the general covering, and the individual hairs of which are strong and almost 

 bristly, pale yellowish- grey below, and broadly tipped with blackish-brown, and in 

 some cases with a narrow terminal band of pale yellowish-brown. The grizzling is 

 produced by the yellowish wavy hairs appearing among the longer and stronger 

 hairs. 



The skull is remarkable for the long narrow facial portion, and for the little 

 convexity of the fronto-nasal region, so that the skull from the vertex to the 

 extremity of the nasals is very straight. The upper incisors are moderately broad, 

 and the molars do not present any characters calling for remark beyond that the 

 last molar consists of two folds, a very large broad anterior fold and a small one 

 behind it.
