differences in size, general proportions, colour, and cranial 

 characters it seems best to consider nyansce as a distinct 

 species. We are thus able to deal witii the large Central 

 African shrews as a group apart from Jlavescens and its allies. 

 In tliis iujans<e group we find the tail always unicoloured 

 and not, as in jlavescens, very much paler below than above. 

 Further, there is in this group no distinct line of demarca- 

 tion between the dorsal and ventral surfaces of the body, 

 the transition from the brown-coloured upper parts to the 

 brownish-grey ventral surface i)eing very gradual and 

 indistinct. In the Museum Collection is a fairly large series 

 of specimens which may be taken as representing true 

 iii/ansa ; this form would seem to be restricted to the country 

 arouiul the north end of the Victoria Nyauza. Mr. Kemp 

 collected it at Kirui on Mt. Elgon, at Kagaml)ah, and 

 Mbarara, Uganda; there are also specimens from Entebbe, 

 Mumias, Toro, and Mengo, Uganda. 



(15) Crocidura nyansce kijabee, Allen. 



Crocidura kijubce, Allen, Bull. American Mus. Nat. Hist. xxvi. \\. 173 

 (1009). 



A^'ery similar to nyansce, but rather darker throughout. 



In the original description xVllen writes : " smaller size, 

 relatively much longer taiP' ; the examination of a con- 

 siderable series, both of nyansce and tiie central British 

 East African form, seems to indicate that such dirt'erences 

 are individual and not of systematic importance ; thus, if the 

 figures given below lie compared with the dimensions given 

 by Allen and with the dimensions tabulated above for Neu- 

 mann's species, it will be seen that nyansce and kijubte are of 

 about the same size. 



The colour-difference is not very marked^ but, seen in a 

 series, the general colour of the central British East Aliican 

 specimens is decidedly darker than the average colour of the 

 nyansce series. 



Skull very like that of true nyansce, both in size and 

 dental characters. 



Dimensions of the type (as given by Allen) : — 



Head and body 123 mm.; tail 78; hind foot 19. 



Skull : condylo-iucisive length 30 ; greatest bre:ulth 12 ; 

 interorbital breadth 5'2 ; length of upper tooth-row 1 I-.

 specimens in the Museum Collection: —
