404 RALPH TATE, 
exists another species in the Pliocene of Gourbesville (Manche) ; 
this species (C. Tatei, Cossmann, ms.) has not yet been described, 
but its form is a little more squat, its whorls less numerous and 
narrower, its labial notch is a little broader, etc. 
CHILEUTOMIA suBvaRIcosA, T. and C., spec. nov, (Plate 20, fig. 3.) 
Shell small, pyramidally conical ; embryo orthostrophe of two 
and a-half whorls with an oblique nucleus. Spire-whorls six of 
rather rapid increase, somewhat depressed around the posterior 
suture, thence slightly convex to the front suture ; ornamented 
with oblique growth-lines coincident with the imbricating varices 
which are about one to each whorl. Last whorl large; aper 
ture oval, angular behind and expanding to the front with 4 
continuous thick peristome; labrum arched, notched at the 
inferior angle and varicosely expanded ; columella slightly exc 
vated ; its border callus, reflected and forming a false umbilicus. 
Umbilical groove bordered by an obsolete rim. Length 85, 
breadth 2°5, length of aperture 3° mm. 
Localities: Muddy Creek, Mornington, Curlewis and Fyansford. 
Family Trocuip. 
Genus Infundibulum. 
INFUNDIBULUM LATESULCATUM, spec. nov. (Plate 20, fig. 10.) 
This fossil appears to belong to the Section Infundibulops 
Pilsbry,’ which is distinguished by the thin straight columella 
from its insertion in the centre of the false umbilicus to its unl0? 
with the basal lip. 
Shell widely conical, false-umbilicated ; whorls almost planulate, 
suture not impressed. The sculpture consists of six rounded — 
spiral ridges, narrower than the concave interspaces. Base = 
concave, with eight spiral ridges similar to those on the upp — 
surface. Length 15, breadth 20 mm. 
Eocene, Table Cape, Tasmania (one example).
