Ennea radius, sp. n. (Fig. 8.) 



Shell rimate, ovate, with somemhat acuminate apex, 

 yellowish white, moderately solid; whorls 7, the first six 

 rapidly increasing, the last decreasing, sculptured with some- 

 what distant, arcuate, transverse costulse, which become 

 smaller, more numerous/ and closely set just behind the

llab. Shimbi Hills, British East Africa. 



Closely allied to E. ?ni?iuscula, Mori.*, from the island of 

 Anjouan, but rather more coarsely sculptured than that 

 species, which also lacks the denticle on the columella ; more- 

 over, the projection on the outer lip of E. minuscula is much 

 smaller and not binodulate. 



Martensia gwendolinoe, sp. n. (Fig. 9.) 



Shell differing from M. jenynsi, Pfr., its nearest ally, in its 

 more inflated whorls, more convex base, and in the spiral 

 sculpture, which is much finer in the present species. 



Alt. 9"25, diam. maj. 12, diam. min. 10*75 mm. 



Aperture : alt. 5*5, diam. 5 mm. 



Hob. Usagara, German East Africa.

 gated on the base with greyish streaks and blotches, painted 

 on the last whorl with a reddish-chestnut peripheral band ;
