No. 259. Bulimus? (Pomatias?) Vectiensis, F. E. Edwards. Tab. XXXIV, fig. 7 a, b. 



Spec. Char. B. Testa elongato-conicd, spird elevatd, apice acuminato ; anfractibus 

 septenis subplanis, lente crescentibus, suturd distinctd, basi subangulatd, aperturd obliqud ; 

 labro acuto simplici. 



Height, i- 6 -ths of an inch ; breadth, j^-ths of an inch. 



Locality. Sconce {Edwards). 



This is another fossil from that rich locality in the Isle of Wight in Mr. Edwards's 

 Collection. I have adopted the specific name which he has given to it. As to the genus 

 it does not from its shape strictly deserve the name of Bulimus, and I have therefore 

 referred it only provisionally to that genus ; indeed, so close do some of the so-called 

 Cyclostomce approach other shells called Bulimi that it is difficult to draw a satisfactory 

 line between them. The nearest resemblance to this shell known to me is Bulimus 

 turgidulus, Desh., 1 An. sans Vert, du Bas. de Par./ t. xi, p. 833, pi. liv, figs. 25 — 27 ; 

 but judging from the figure and description of that species, it is, I think, quite distinct.

Succinea Spaknacensis, Desh. An. sans Vert, du Bas. de Par., t. ii, p. 795, pi. Hi,

Spec. Char. S. Testa elongato-ovatd, obliqud, tenui, lavi ; spird acutiusculd; anfrac-

 Length, y^ths of an inch. 

 Locality. Headon Hill {Edwards). 



A very perfect specimen of a species of Succinea is in Mr. Edwards's Cabinet, of 

 which the figure as above referred to is a representation. It has somewhat the appear- 

 ance of a recent specimen from its perfection, but seems to want the amber-coloured 

 tinge of the common living shell. So little difference is shown among the so-called 

 species of this genus that it becomes a matter of extreme difficulty to distinguish them ; 

 I give it, however, as a fossil from its being in Mr. Edwards's Collection and marked from 

 Headon Hill, but I cannot warrant its genuineness. The specific name of gracilis is 

 attached to Mr. Edwards's specimen, and I would have adopted it, but this name has been
