IJab. Bibianaha, near Dunkwa, inland of Sekondi, Gold 

 Coast. 



Tt/pe. Old female. B.M. no. 10. 8. 1. 1. Original num- 

 ber 14. Collected 27th June, 1910, and presented by 

 Dr. H. G. F. Spurrell. 



This fine shrew is intermediate between the very large 

 W.-African species C. goliath, giffardi, and manni, and the 

 more normal-sized species such as C. poensis &c. Its short 

 fur, greyisli colour, and narrow skull will also readily distin- 

 guish it from any of its allies. 



I have named it in honour of its discoverer Dr. H. G. F. 

 Spurrell, to whom the National Museum owes an interesting 

 collection of small mammals from the Gold Coast. 



Tatera gamhiana, sp. n. 



A large pale species ; tail almost without tuft. 



Size about as in T. kempi, the only large * W.-African 

 species hitherto known. General colour much paler than in 

 that animal, dull fawn, more buffy on the sides. Under 

 surface, hands, and feet white as usual. Tail about as long 

 as head and body, very inconspicuously tufted at the tip, brown 

 above, white on sides and below. 



Skull readily distinguishable from that of T. kempi by the 

 shape of the interparietal, which is broad transversely, 

 narrow antero-posteriorly, its breadth considerably more than 

 twice its length. Anterior palatal foramina not reaching 

 back to the level of the front edge of the root of m^. Bullae 

 about as in T. kempi. 



Dimensions of the type (measured in flesh) : — 



Head and body 162 mm.; tail 162 ; hind foot 35 ; ear 21. 



Skull : greatest length 41 ; basilar length 33'5 ; greatest 

 breadth 21*7; nasals 15; interparietal 4x10*3 (4*3 X 8:7 in 

 T. kempi) ; palatal foramina 7*8; bulla 11; upper molar 

 series 6*7. 



Hah. Gambia. Type from Marakissa ; alt. 500'. 



Type. Adult male. Original number B. 14. Collected 

 15th May, 1910, and presented by Mr. G. Fenwick Owen. 

 Five specimens examined. 



The only member of this group previously known was the 

 T. kempi of S. Nigeria, which is a much darker-coloured 



* The feet of T. guiance are as long as in T. kempi, but the skull is 

 markedly smaller.
