convex whorls, nucleus minute, rounded. Whorls 9, lightly convex 

 and contracted at the suture, the first four whorls more rounded than 

 the others ; varices few, interrupted, irregularly disposed, and not well 

 marked ; base rounded. Suture very distinct, impressed. Aperture 

 subvertical, rather large, obliquely quad.rate, broadly angled above, 

 flatly expanded at the base. Outer Up not much strengthened, but 

 slightly curved, and forming a broad rounded angle at the junction 

 with the basal lip. Columella stout, nearly straight, rounded on joining 

 the basal lip, both being distinctly everted. Inner Up broadly re- 

 flexed over the pillar, and forming a thin callus on the parietal wall. 

 Operculum unknown. 



Diameter, 2-1 mm. ; height, 5mm. 



Animal unknown. 



Type in the Dominion Museum, Wellington. 



Hob. Off Great Barrier Island, in 110 fathoms (type). 



Remark. This species is allied to the Australian E. munita, Hedley, 

 from which it may be distinguished by its smaller size, fewer whorls, 

 the less prominent varices, and more feeble sculpture.
