Hab. Duque de Braganca, Angola. 



Type. Adult female. B.M. no. 4.4.9.29. Original 

 number 156. Collected by the late Dr. W. J. Ansorge. 



There is a second specimen of this new shrew in the 

 collection, the skull-dimensions of which are given above. 

 It agrees fairly closely with the type in general body- 

 measurements (head and body 85 mm. ; tail 65 ; hind foot 

 165 ; ear 10). 



The exact affinities of this species are somewhat difficult 

 to decide ; for the present it seems most convenient to 

 regard it as intermediate between the turba and poensis 

 groups. From turba it is distinguished by its paler colour, 

 longer, less hairy tail, and rather larger hind feet ; zena, the 

 other Bangweolo species, is very much darker in colour, 

 both above and below. Crocidura p. soricoides possesses a 

 larger skull, broader and flatter brain-case, and is con- 

 siderably browner in colour. Crocidura nigricans, from 

 Angola, is a much smaller animal (head and body 70 mm. ; 

 tail 52; hind foot 12). 



i(56) Crocidura poensis, Fraser. 



Sorex {Crocidura) poensis, Fraser, P. Z. S. p. 200 (1842). 



A medium-sized, dark brown-coloured species. 



The upper parts are described as u of a deep brown colour, 

 rather indistinctly variegated with greyish " ; the body 

 beneath is " grey, but slightly washed, as it were, with dirty 

 yellow." In the Museum Collection there are four speci- 

 mens from Fernando Po which may be accepted as repre- 

 senting Fraser' s species; the colour of the new unworn 

 pelage is considerably greyer than in the bleached phase, 

 about as in " fuscous "; in the bleached state the coat is 

 much browner and redder, near " P rout's brown." Flanks 

 rather greyer, the brownish tint gradually passing into the 

 grey of the belly. Ventral surface pale slaty grey (" neutral 

 grey ") ; in the worn coat the colour of the belly is con- 

 siderably browner (" neutral grey " suffused with " drab ").
