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 8-10ths of an inch; diameter, 4-10ths of an 

 inch.

L. testa elongato-ovatd, sub-turritd, sexies vel septies circumvolutd ; spird exsertd, 

 acuminata; anfractibus convexis, substriatis : aperturd rotundato-ovatd, ampld, spiram in 

 longitudinem csquanti ; plied columellari parvd, angustd, rotundatd, parum tortuosd, 

 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 L. longiscata, and 

 in fact the present shell presents a close analogy with that species. It is, however, 

 distinguished from L. longiscata, as well as from L. pyramidalis (Desh.), by the 

 round columellar fold, and the greater convexity of the whorls. 



Size. — Axis, \\ inch; diameter, rather more than ^ an inch.
