120 Mr. 0. Thomas on new 



in Africa forms of the graciUs group are very c<'n-taiit in 

 colour. 



No members of tliis group, light or dark, have been 

 described from the Lake region of (Jentral Africa. 



Crossarchus fasciatus macnirus, subsp. n. 



Size larger than in true /(Jscm^Ms and tail markedly longer. 



Colour quite as in Zululand specimens of fosctatusj the 

 general tone similarly deep and rich, and the shoulders equally 

 shaggy haired and suffused Avilh fidvous (not clear grey). 

 Uands and feet nearly wholly deep glossy bhick. 



Dimensions of the type (measured in tiie fle.-h) : — 



Head and body 378 mm. ; tail 250 ; hind foot 70 ; ear '2G. 



Skull: condylo-basal length 71; basal length ()7 ; zygo- 

 matic breadth 38'5 ; median length of nasals 12*5; })al;ital 

 length 38 ; greatest diameter of ^y'* C. 



J/ab. Euwenzori South-east. Alt. 3100'. 



Ti/pe. Male, adult but not old. B.M. no. G. 12. 4. 2'J. 

 Original number 133. Collected 30th April, 190G, by li. E. 

 Dent. A second specimen (no. 071), collected the s;une day 

 by K.. B. Woosnam. 



Two examples of tvue fascia t us, collected in Zululand by 

 C. H. B. Grant, measure — head and body 333 and 335 mm., 

 tails 207 and 209 mm. respectively. No. G71 of macrurua 

 measures — head and body 380, tail 270 mm. There is 

 evidently, therefore, go material a difi'eience in size and in 

 Jenglh of tail between the Kuwenzori form and the South- 

 African that subspecific distinction is necessary, in spite of 

 the close resemblance in other characters. 



Sciurus rvfuhrachiatus semh'kii, subsp. n. 



Most closely allied to S. r. nyansm, Neum.*, with which it 

 agrees in the extent of the rufous on the limbs, but distin- 

 guished by the speckling of the back being very much finer 

 and by its grever general colour. In nt/ansce there is a strong 

 BufFusion of buffy or fulvous in the dorsal colour, the rings of 

 the longer hairs and the ends of the wool-hairs being markedly 

 tinged with buff"y ; in semliliit, on the other hand, the former 

 are almost white and the latter are dull greyish buffy. As a 

 result the general toie of semlikii is a nearly pure daik grey, 

 between grey no. 6 and " smoke-grey " of llidgway, tiie 

 middle line of the back only with slight ytllowi.-h suffusion. 

 Dimensions of the type (measured in liie flesh) : — 

 Head and body 225 mm.; tail 251; hind foot 19; ear IG.
