helonginfj to the Genus CrociJura. 505 



This large East-African shrew is probably most nearly 

 related to hedenborgiana. 



(13) Crocidura fuscosa, Thos. 



Crociflura doriana fuscosa, Thomas, Ann. & Mag. Nat Hist. (8) 

 vol. xii. p. 90 (1913). 



A (lark chocolate-coloured species with black feet and 

 tail, most nearly related to hedenboryiaaa, but rather lighter 

 in colour and smaller. 



Cieiieral dimensions distinctly less thaa in Sundevall's 

 species. 



Colour of dorsal surface very dark chocolate (between 

 " bistre '' and *• vandyke-brown 'j above and below, the 

 ventral surface very slij.5htly paler; hairs all with slate-grey 

 bases and dark brown lips. Backs of hands and feet black, 

 much darker than in any of the nyansa group. Tail black 

 al)ove and below, more hairy tlnm in nyansa, with the caudal 

 bristles black in colour and conspicuous. The skull of the 

 unique type is unfortunately badly broken, only the brain- 

 case, intercjrbital region, a portion of the maxilla, and man- 

 dible remaining. In size it is evidently smalit-r than in 

 hedenboryiana, having a narrower brain-case and smaller 

 teeth. 



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



Head and body 114 mm. ; tail GO ; hind foot 19 ; ear \:l. 



Skull (broken): greatest breadth of brain-ease ['1'7 ; 

 combined length of three upp>;r molars 4'8 ; of three lower 

 molars 5 5.

This species was originally described by Thomas as a race 

 oi doriana ; the great difference in general colour, the uni- 

 colourcd tail, and dark ventral surface seem to indicate that 

 it must be considered as a form quite distinct from donuna. 

 Its nearest relation would appear to be hedenborgiana, from 

 which species fuscosa may be distinguished by its rather 

 paler colour and smaller size. 



(14) Crocidura ngansa, Neum. 



Crocidura Jlavescens nyansce, Neumann, Zool. Jahrb. Abth. Syst. 

 vol. vi. p. 544 (1900). 



Considerably larger than the South African jlavescens. 

 Colour darker throughout. 



General dimensions large, hind foot, in adult specimens, 

 measuring 20 mm. in length.
