Shell ovate-elongate: spire elevated, fastigiate, apex acuminate: whorls 

 seven, flattened on the sides, posteriorly rather roundly angulate and gradate- 

 subcanaliculate ; body-whorl a little exceeding half the total length of the 

 shell, broadest at the angle, narrowing forwards and produced in front : 

 suture almost linear and scarcely impressed, and bordered by a thin and 

 slightly elevated rim rising from each successive whorl: aperture longitu- 

 dinal, narrow, moderately attenuated in front ; columella imperforate, appar- 

 ently thinly overspread with callus. 



Described from a single specimen retaining the test nearly entire. 

 Length, 0-1 mm., originally about 66 mm.; width, 33 mm., original width 

 about 35 mm.; length of body-whorl to suture, 31 mm.; length of spire, 

 from suture of body-whorl, when entire, about 32 mm.

 division, generic or subgeneric, whether that group be termed Euspira or
