The figure accompanying Mr. Tenison-Woods' memoir above 

 referred to is very poor, representing a shell with the greater 

 part of the body-whorl broken away. Professor Tate's inter- 

 pretation is here accepted. Shell solid, turriculate; from 8 to 9 

 convex whorls, the suture being impressed ; ornament consisting 

 of distant, bold spiral ridges between which smaller spiral striae 

 occur, towards the base of the body-whorl is a conspicuous spiral 

 carina ; aperture small, ovate, wide in front ; outer margin thin, 

 having a small denticle as a prolongation of the carina ; inner 

 margin smooth, slightly callous and denticulate near the posterior 

 channel, Urate in front ; canal short, bent, and twisted. 



Bimennons. — Length 32 mm.; breadth 13 mm.; length of 

 aperture and canal 15 mm. 



Form, and Loc. — Eocene : Victoria.

Closely allied to E. ino, of which it may be only a variation 

 in form, but it is more slender and elongate, the sculpturing 

 consists rather of small sulci than ridges. Protoconch (Plate VI. 

 Figs. 2a-h) identical with that of E. ino, consisting of two smooth, 

 rapidly increasing whorls, the later portion of which is inflated 

 and terminates abruptly, the brephic stage commencing suddenly 

 by having broad and deep spiral sulci.
