110 Messrs. J. C. Melvill and J. H. Pousonby on 



16. Ennea Vandenbroeckii, sp. n. (PI. III. fig. 16.) 



E. testa obeso-cylindrica, cinerea, apice obtuso ; anfractibus octo, 

 undique longitudiuabter oblique striato-costatis ; apertiira ovato- 

 rotunda ; peristomate albo, refiexo, quiuqueplicato, plica parietali 

 conspicua, incurvata, labiali simplici, dentibus basalibus duobus 

 simplicibus, plica columellari interna mammaeformi. 



Long. 7, lat. 3'50 mill. 



Hab. Natal {ex Coll. Vandenbroeck) . 



Marked by Mr. Vandenbroeck as E. Gouldi (Pfr.), which 

 it certainly is not. A bluntly cylindriform obese shell, with 

 the whorls striate- costulate longitudinally ; mouth round, 

 five-plaited or toothed. In form allied to E. Dankeri^ Pfr. 



Two specimens. 



17. Ennea vansfaadensi's, sp. n. (PI. III. fig. 17.) 



E. testa rimata, longa, cyliudrifonni, delicatula, succinea ; anfrac- 

 tibus sex vel septem, undique confertim longitudinaliter tenui- 

 striatis ; peristomate albo, inerassato, nitente, plicis vel dentibus 

 quatuor munito, plica parietali conspicua, prominente, intus 

 extensa, dente labiali bifurcate, basali minore, simplici, plica 

 columellari mammaeformi. valde intrante. 



Long. 5-50, lat. 1-75 mill. 



Hab. Van Staaden's River {J. Crawford, Esq.). 



Four specimens, of whicli the one we have taken as the 

 type is completely cylindriform, prolonged^ seven- whorled ; 

 the other three are somewhat shorter, but the mouth and 

 tooth-processes are exactly the same. 



18. Succinea Bowkert, sp. n. (PI. III. fig. 18.) 



S. testa pertenui, Isete ochracea ; anfractibus tribus vel quatuor, 

 ultimo rapide accrescente, subeffuso, apicali parvo, medio per- 

 ventricoso, parvo; apertura ovata, labro tenuissimo, simplici. 



Long. 13"50, lat. 9 mill. 



Hab. Malvern {Col. Bowker). 



We are unable to exactly match this shell with any known 

 forms, though it approaches two Sandwich-Island species, 

 both endemic. It does not appear either to be a variety of 

 the ubiquitous S. putris, and we have therefore ventured to 

 describe it. The species of this genus unfortunately are not 

 only liable to much variation, but also offer no very salient 

 points for characterization. 



Two ppecimene^, exactly similar.
