Ennea parallela, sp. n. (PI. VIII. fig. 9.) 



E. testa vitrca, tenui, recto cylindrica, angusta, obscure et evaiiide 

 tenuistriuta ; anfractibus 7, apico perubtuso, supernis tumidis, 

 tribus ultimis fere rcctis, ad suturas iiupressis, ultimo pro rata 

 parte parvo ; apertura rotunda, peristomute la)vi, albo, liaud 

 multuni incrassato, dentibus plicisvo ijuatuor instructo, plica 

 parietali acuta, iiitrante, dento labiali iuconspicue bifido, basali 

 minuto, plica columellari coutorta, magna.

AVe have selected as the type of this small Ennea a speci- 

 men slightly more elongate in torm than the tew others yet 

 seen by us, because it appears to be quite adult and in espe- 

 cially good condition. The others are proportionately shorter 

 and more delicately striate ; these striae seem evanescent, and 

 iiave indeed almost disappeared in the well-grown type. We 

 do not know any species very nearly akin to this. It 

 resembles E. crispula^ described in this paper, in form and 

 (iisj)osition of peri.stomatal processes, but is abundantly 

 distinct in texture and other ))articulars. E. mar'ue, M. & P., 

 Irom Somerset East^ may perhaps likewise be compared. 



Ennea periploca'^ , sp. n. (PI. VIII. fig. 10.)

Ilah. Boschberg Mt., Somerset East (J. Farquhar). 



As the name would imply, the peristomatal processes of 

 this very refined little species are indeed involved and promi- 

 nent. It is one of the smallest species known to us and one 



* n(pin\oKoi, intricate.
