new Mollusks from South or Central Africa. 93 
We have much pleasure in associating the name of Mr. 
Layard’s god-daughter, Miss Mary Layard Bowker, with both 
this and the preceding species, both having been discovered 
by her, and, as far as we can ascertain, found by her alone. 
16. Ennea aperostoma, sp.n. (Pl. VI. fig. 10.) 
£. testa parum rimata, cylindrica, albo-cinerea, pellucente ; anfrac- 
tibus septem, ad apicem compressulis, obtusis apud suturas 
impressis, striis obliquis undique longitudinaliter instructis ; 
apertura ovato-auriformi; peristomate crassiusculo, triplicato, 
plica parietali columellarique utraque prolongata, valida, profunde 
intrante, labro intus tridentato. 
Long. 8°75, lat. 3°50 mill. 
Hab. Natal (H#. L. Layard). 
Allied to L, Wahlbergi (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. ‘The other two are quite smooth, and we would desig- 
nate these as var. /issophanes, which seems in other respects to 
agreewith the type. ‘his 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 character 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. Ennea scrobiculata, sp.n. (PI. VI. fig. 8.) 
E. testa rimata, breviter cylindrica, albo-cinerea, subdiaphana ; 
anfractibus novem, tribus ad apicem gradatim decrescentibus, 
quatuor his proximis fere uniformibus, duobus ultimis majoribus, 
omnibus striis obliquis confertim longitudinaliter decoratis, 
anfractu ultimo extus multum scrobiculato et prolongato; aper- 
tura trigona; peristomate incrassato, plica parietali magna, 
columellari valde intrante et ad imam faucem fere omnino aditum 
claudente, dente labiali patulo, 
Long. 5°75, lat. 2 mill. 
Hab. Natal (HZ. L. Layard). 
This shell is queried by Mr. Layard as appertaining to H. 
Kraussi (Pfr.). It is an extremely interesting little species, 
owing to the attenuated constriction behind the outer lip; the 
mouth is well furnished with plice and teeth large in propor-
