MUS FREMENS Miller. 



1902. Mils fremms Miller, Proc. Acad. Nat. Sci. Philadelphia, 1902, p. 154, 

 March, 1902; Sinkep Island, off east coast of Sumatra. 



Twenty-four specimens, from the following localities : Fulo Tuangku, 

 7(2 skulls without skins); Pulo Bangkaru, 1; Pulo Mansalar, 7 (1 

 skull without skin); Tapanuli Bay, 9 (5 skulls without skins). This 

 series shows variation in both size and color, but for the present I 

 prefer to refer it as a whole to Mus fremens. None of the skins 

 show an}" close approach to the bright colors of Mus vociferans. For 

 measurements, see table.

 MUS ASPER Miller. 



1900. Mus asper Miller, Proc. Biol. Soc. Washington, XIII, April 21, 1900, p. 

 145; Trong, Lower Siam. 



An adult male (skin and skull) and female (skull onl}^) from Pulo 

 Tuangku, Banjak Islands, and an adult female (in alcohol) from Tapa- 

 nuli Bay. These specimens so closeh^ resemble JIu-s aspt/' that with- 

 out further material I am unable to distinguish them. The male from 

 Pulo Tuangku measures: Total length, 249; head and body, 140; tail, 

 109; hind foot, 29.6 (28). The female from Tapanuli Bay measures: 

 Total length, 210; head and body, 105; tail, 105; hind foot, 27 (26).
