lineis transversis sed irregularibus instructis, et lineis tenuissimis longitudinalibus trans- 
versisque decussatis ; apertura ovata, labro externo tenut. 
Shell ovately ventricose, spire elevated and pointed, whorls (6) rather convex, with deep 
sutures ; the last whorl large, oblique, its surface punctated and cingulated ; puncte minute, 
disposed in close but irregular arranged transverse lines ; they are decussated by numerous 
very fine lines, both longitudinal and transverse ; the entire surface of the whorl is likewise 
divided into several (4 or 5) encircling zones by as many lines, which are prominent, 
rendering the spaces between them rather flattened; aperture ovate, outer lip thin, inner 
lip rather flattened and excavated. Axis 11 lines, transverse diameter 8 lines. 
The following is Mr. Bean’s original notice of this species : 
“Shell turbinated, finely striated longitudinally and transversely, which, under a high 
magnifier, gives it a very beautiful appearance ; whorls (6) rounded and well divided, the 
body whorl occupying one half the length of the shell. Aperture elliptical, pillar lip thick 
and a little flattened, outer lip very thin; length nearly 3 inch, breadth } inch. The only 
specimen procured from the Cornbrash; but in the Inferior Oolite at Peak Hill it is not 
uncommon. The specimens found there are larger, coarser, and the spire is not so much 
produced.” 
Locality. Bath Oolite near Scarborough. In the collection of Mr. Morris.

NV. Testé ovati, spird elatd, anfractibus (4) latis, superné carinatis, suturis canaliculatis ; 
anfractu ultimo, bicarinato ; aperturd ampld, suborbiculari. 
Shell ovate, spire elevated, whorls (4) broad, their upper portion with an obtuse 
encircling carina; the sutures channelled; the last volution, with an obtuse carina, 
occupying very nearly the middle of the volution ; aperture large and suborbicular. 
The specimen placed at our disposal, by the kindness of Mr. Bean, is the original one 
figured by Professor Phillips. It is rather compressed, which gives an appearance of 
greater breadth to the shell than it possessed; the perfect form would approach our 
FE. pyramidata, from which it is distinguished by the second carina, which is not less 
strongly marked than the upper one. Length 15 lines, breadth (uncompressed) 
103 lines. 
Locality. Great Oolite near Scarborough.
