Veiy typical examples but with the white of the underparts 

 continued to the hind foot. Above mingled ochraceoiis and brownish- 

 black, pelage very stiff and wiry ; below white. Hands and feet white. 

 Tail bicolored with a white tip.

This race differs from 2?. s. surifer in being rather duller in 

 colour above while the white of the undersurface is usually continued 

 to the hind foot, tiie contrary being generally the case with that form. 

 The series from Hinlap is even duller and more blackened than para- 

 types from the extremity of South-east Siam, but several of the speci- 

 mens are somewhat immature.

These specimens are evidentlj' the same as Flower's Bangkulc 

 rats, and also seem to agree with E. r. porlus, mihi, from Koh Si Chang, 

 but the material is insufficient for satisfactory determination.
