Type. Adult. B.:\I. no. 90. 3. 6. 1. 



In the Collection there are two further specimens of this 

 minute Somali shrew, both exactly like the type in general 

 colour and dimensions. 



The small size, greyish-brown upper parts, whitish belly, 

 and very small flat skull readily distinguish nana from all 

 the preceding species.
