 Long. 6-0, lat. 2o0 mm. (spec, min.). 



Hah. Durban, Natal (Quekett). 



Seven examples, of which we take the largest for the type; 

 the remaining six are all much of a size. A very remarkable 

 and beautiful Ewiea, tun-shaped, narrowly rimate basally, 

 shining, almost smooth ; whorls eight, apex very obtuse, the 

 whorls being impressed at the sutures ; just at and below these 

 for a very short distance oblique striations are discernible with 

 a lens ; the sculpture soon becomes obliterated, and the body 

 of the shell is smooth. At the base and round the perforation 

 the striations reappear. The aperture is roundish ; peristome 

 white, shining, peristomatal processes various and conspicuous, 

 being as follows : — 



(i.) An oblique large parietal plait, 

 (ii.) Two labial teeth, effuse and prominent, 

 (iii.) One basal tooth, acutely produced, 

 (iv.) A rounded columellar simple tooth. 

 (V.) An internal bipartite columellar plait, much produced 

 and almost closing the aperture. 



Succinea piscinaliSy sp. n. (PI. VII. fig. 4.) 



S. testa ovato-acuminata, tenui, semipellucida, ochracea, apice sub- 

 mamillato ; anfractibus quatuor, apud suturas declivibus, im- 

 pressis, rapide supra attenuatis, ultimo amplo ; apertura ovata, 

 labro paullum effuso, baud incrassato, simplici. 



Long. 11, lat. 5 mm. 



Hab. Fish River {Farqukar, in coll. T. Rogers). 



Several examples of a Succinea, normal in its outlines, 

 which nevertheless hardly agrees with any other species known 

 to us. It is ovate, much acuminate, and becoming rapidly 

 attenuate towards tlie apex, four-whorled, including the almost 

 mamillate apical whorl, the last being, as usual, very much 

 the largest ; the aperture is oval, outer lip slightly effuse, 

 simple. 



We are indebted for this shell to Mr. Thomas Rogers, of 

 Manchester, who, as stated above, received it as collected by 

 Mr. Farquhar.
