530 PROCEEDINGS OF THE ACADEMY OF [1896. 



Ouly one specimen of this genus is in the collection. It is an 

 adult female with teeth well worn and showing plainly three pairs 

 of teats, pectoral, abdominal and inguinal. 



The specimen is in spirit. It differs decidedly from S. pratensis 

 and S. krebsi, as figured and described in Peters' work on the 

 mammals of Mozambique, in its diminutive size. Its tail is also 

 relatively much shorter and the ears smaller than in either of these 

 species. Its colors resemble those given in Peters' plate (I. e.) of 

 " edulis," but lack the fawn tint of that species.

33. Mus microdon Peters ? 



One specimen, (No. 3,908), a female, taken April 24, 1895, agrees 

 very well with the figures of Peters' types, and the measurements 

 also coincide very closely with bis. The tail is unicolor, naked, 

 shiny brown, tessellated with geometrically arranged scales. The 

 belly and feet are whitish, the lateral stripe fulvous, the back dark, 

 grizzled, brown-black. 



34. Mus sp. ? 



Two immature males, (Nos. 3,884, 3,891), with plumbeous body, 

 white feet and naked tail of the length of the body without head, 

 comes from Sheikh Husein ; October 12, 1894. They diflfer from any 

 other species in the collection. 



35. Mus sp. ? 



A series of four skins with skulls, and five specimens in alcohol,
