new MoIhtsJcs from South or Central Africa. 93 



We have much pleasure in associating the name of Mr. 

 Layard's god-daughter, Miss Mary Layard Bowkcr, witli Loth 

 this and the preceding S[)ecics, both having been discovered 

 by her, and, as far as we can ascertain, found by her alone. 



16. Ennea aperostoma, sp. n. (PI. VI. fig. 10.) 



E. testa parum rimata, cylindrica, albo-cinerca, pcllucente ; anfrac- 

 tibus septcm, ad apicem comprossulis, obtusis apud siituras 

 imprcssis, striis obliquis umliquo longitudinaliter instructis ; 

 ajiortura ovato-aurit'ormi ; poristoinate crassiusculo, triplicato, 

 plica parietali coluniellaricjuo utraque prolongata, valida, profuudo 

 intraute, labro inlus tridentato. ^ 



Long. S-75, lat. ii'50 mill. 



Hab. Natal {E. L. Layard). 



Allied to E. Walilheryi (Pfr.). There are three specimens 

 on the tablet in Mr. Layard's collection, of which we have 

 taken that with the whorls delicately obliquely striated as the 

 type. I'he other two are quite smooth, and we would desig- 

 nate these as var. lissophanes^ which seems in other respects to 

 agree with the type. This species is at once distinguished from 

 any others of the genus described in this or our former paper 

 ('Annals,' Sept. 1891) by the comparatively open chai-acter of 

 the mouth. This is ovately auriform ; the parietal plait is 

 well developed ; the columellar tooth is broad, flat, and enters 

 deeply into the shell ; there is a small tooth at the base and 

 the outer lip is furnished with a raised callus from which 

 spring two teeth, the lower one small, the upper one larger 

 and entering more deeply. 



17. Etuiea scrobiculata^ sp. n. (PI. VI. fig. 8.) 



E. testa rimata, breviter cylindrica, albo-cinerea, subdiaphana ; 

 anfractibus novem, tribus ad apicem gradatim decresceutibus, 

 quatuor his proximis fere uniformibus, duobus ultimis majoribus, 

 omnibus striis obliquis cont'ertim longitudinaliter decoratis, 

 anfractu ultimo extus mnltum scrobiculato et prolongato ; aper- 

 tura trigona ; peristomate incrassato, plica parietali magna, 

 columellari valde intrants et ad imam faucem fere omnino aditum 

 claudente, dente labiali patulo. 



Long. o'Vo, lat. 2 mill. 



Bab. Natal {E. L. Layard). 



This shell is queried by Mr. Layard as appertaining to E. 

 Kraussi (Pfr.). It is an extremely interesting little species, 

 owing to the attenuated constriction behind the outer lip; the 

 mouth is well furnished with plicie and teeth large in propor-
