370 Mr. M. A. C. Hinton on 
Size slightly larger than in ruddi, but tail considerably and 
hind foot slightly shorter. Fur long and crisp as usual ; 
scales of tail 13 in 10 mm. 
General colour of upper parts near olive-brown, the top of 
the head and mid-dorsal region lacking the dusky suffusion 
seen in ruddi, brightening on flanks to a clear buffy brown. 
Underparts dirty white, with the Lophuromys-like appearance 
characteristic of all the species of the genus. Mamme 
3—3=12. 
Skull most like that of ruddi, but distinctly larger. Inter- 
orbital region apparently broader, the temporal ridges being 
straight instead of curved and less abruptly convergent ante- 
riorly. Zygomatic plate a little wider, the upper part of its 
anterior border thrown rather more boldly forwards. 
Measurements of type taken in flesh by collector (those of ruddi added 
in parentheses):—Head and body 134 (118) mm.; tail 69 (77); hind 
foot 18°3 (19) ; ear 17°65 (15). 
Skull-measurements (those of rwddi in parentheses): condylo-basal 
length 30:1 (28-7); occipito-nasal length 27 (25:1) ; zygomatic breadth 
15:8 (15°4) ; interorbital constriction 5°38 (5:1) ; cranial width 12-2 (12°6) ; 
median occipital depth 7°8 (81); condyle to m.* 14:1 (13°7); anterior 
palatal foramina 7°5 (7:7); nasals 10-633 (10x3°3); dental length 
16:2 (15°6) ; cheek-tooth on crowns 5 (4°38). 
Hab. 8. Nyasaland. 
Type. An old female, with cheek-teeth greatly worn. 
B.M. no. 21. 2.16.1. Original number 280. Collected 
Oct. 27, 1917, at Cholo, Nyasaland (altitude 2700’), by 
Mr. Rodney C. Wood. Caught “in hole of mole-rat on 
wooded hills.” 
I have great pleasure in naming this interesting species in 
honour of Mr. R. C. Wood, who has made a very beautiful 
collection of the small mammals of Nyasaland. U. wood is 
quite closely related to U.ruddt, the original species described 
by Dollman from Mount Elgon. It is, however, clearly 
differentiated from ruddi by its shorter tail, lighter colour, 
and the peculiar form of the anterior part of the brain-case. 
From the species next described it is widely different. 
Mr. Wood deserves credit for first observing the mammary 
formula, not hitherto determined in this genus; his count of 
3—3 = 12 is confirmed by the skin. 
Uranomys tenebrosus, sp. n. 
An unusually dark species, with large cheek-teeth. 
Fur long, dense: and crisp as in other species; general 
appearance much like that of a Lophuromys. Colour of upper 
surface very dark, about “olivaceous black” of Ridgway
