lineis transversis sed irreyularibus instructis, et lineis lenuissimis lonyitudinalibus trans- 

 versisque decussatis ; aperturd ovatd, labro extcrno tenui. 



Shell ovately ventricose, spire elevated and pointed, whorls (6) rather convex, with deep 

 sutures ; the last whorl large, oblique, its surface punctated and cingulated ; punctee 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 occiipying one half the length of the shell. Aperture elliptical, pillar lip thick 

 and a little flattened, outer lip very thin ; length nearly f 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 spive is not so much 

 produced." 



Locality. Bath Oolite near Scarborough. In the collection of Mr. Morris.

N. Testa ovatd, spird data, anfractibus (4) latis, superne carinatis, suturis canaliculatis ; 

 anfractu ultimo, bicarinato ; aperturd ampld, sulorliculari. 



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 

 E. 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) 

 lines. 



Locality. Great Oolite near Scarborough.
