 below slate-black. Ears almost round, sparsely covered with 

 short reddish-brown hairs. Tail unicoloured brown, prac- 

 tically naked, though evenly covered with short stiff hairs. 

 Scales in rings 10 to 9 millim. Feet very short and stout. 

 Hind feet with only 5 pads, 1 and 2 well developed, 3, 4, and 

 5 small, hardly more than 1 millim. in length.

This is a peculiarly Dasi/nii/s-Yike rat in shape and texture 

 of fur ; in colour it closely resembles Dasymys Bentleyce. 

 The skull is also somewhat Dasymys-Wkt, having rather 

 strong zygomata, broad teeth, and long narrow palatal 

 foramina ; the latter are peculiar, reaching to fully the middle 

 of the first molar, so that their length very nearly equals that 

 of the diastema. When damp the fur shows iridescent colours 

 of dark green, but not nearly so bright as in the next species. 



The specific name is given in honour of the head of the 

 Mammal Department of the British Museum, to perpetuate 

 his connexion with this genus. 



Dasymys nxidipeSy Peters. 



One male, Caconda ; one male, Hanha. 

 This animal shows very beautiful dark iridescent green 

 colours when wet. 



Golunda fallax, Peters. 



Male and female, Hanha. 



Shows no iridescent colours when wet. 



Saccostomus mashonce^ de Winton. 



Saccostomus mashotice, de Wintou, P. Z. S. 189G, p. 804. 



Male and female, Caconda. 



Although these specimens differ in colour (being uniform 

 drab) from those from the typical locality, I can find no 

 differences in the skulls, and we do not know sufficiently 

 about seasonal changes to separate these mammals on colour 

 alone.
