19°5 x 17. 
Skull: greatest length 36 millim.; greatest breadth 18 ;

parietal bone 4°6 x 9; basal length 32; henselion to back of 
palate 17; back of palate to foramen magnum 12:5; palatal 
foramina 9°6 x 2°5; diastema 10°3; molar series 6°5; outside 
m1 7°5, inside 3°6. Mandible length (bone only) 20, height

This is a peculiarly Dasymys-like rat in shape and texture 
of fur; in colour it closely resembles Dasymys Bentleye. 
The skull is also somewhat Dasymys-like, 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 nudipes, Peters. 
One male, Caconda; one male, Hanha. 
This animal shows very beautiful dark iridescent green 
colours when wet.

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,
