94 EOCENE MOLLUSCA. 
A smooth, ovate, ventricose shell, with a short pointed spire, and formed of five or 
six slightly convex whorls; the aperture pointedly ovate, and the columellar fold 
somewhat angular and prominent, but not much twisted. 
I have not had an opportunity of comparing the English with the French shells, 
and I have therefore some hesitation in pronouncing as to their identity. My 
specimens, however, agree very well with the description and figures given by 
M. Deshayes, (which it must be remembered are taken from casts merely,) except 
that the French shell is described as formed of four whorls only, and as having the 
aperture contracted at the base; but the figures show six whorls, and the aperture, as 
drawn, is scarcely more contracted than that of the English shell. 
Size.—Axis, rather more than 8-l0ths of an inch; diameter, 4-l0ths of an 
inch.

L. testa elongato-ovatd, sub-turritd, sexies vel septies circumvoluta; spird exserta, 
acuminata; anfractibus convexis, substriatis: apertura rotundato-ovatd, ampla, spiram in

proeminenti. 
An elongated ovate shell, with an elevated pointed spire; volutions six or seven, 
very convex, almost ventricose, the edges of which are depressed along the suture, 
and, generally, present a sharp stria running round them, parallel with and at a short 
distance below the suture,—similar to that mentioned by Brard as characterising his 
L. pyramidale: the lines of growth are so strongly marked that the surface of the 
shell almost appears to be striated. The aperture is roundedly ovate, somewhat 
effuse, and barely exceeds the spire in length; the columellar fold is narrow, rounded, 
not much twisted, and prominent. 
The line of suture frequently runs below the wide part of the whorl, giving a 
distorted appearance, resembling that which is sometimes seen in ZL. longiscata, and 
in fact the present shell presents a close analogy with that species. It is, however, 
distinguished from JZ. longiscata, as well as from L. pyramidalis (Desh.), by the 
round columellar fold, and the greater convexity of the whorls. 
Size-—Axis, 14 inch; diameter, rather more than } an inch. 
Locality—Headon Hill.
