 The shell in an alcoholic specimen is almost completely covered 



by the mantle, except a small space 3| mm. across. Both foot and 

 mantle spotted with dark grey, and the whole length, when con- 

 tracted in alcohol, is 42 mm. The posterior portion of the foot is 

 very high and sharply ridged. The shell is evidently soft and 

 membranaceous.

Shell ovate, slightly convex above, concave below, the apex 

 inclined towards the left, but not involute nor forming a closed

[Tlie shell is very different from that of Girasia, being far more 

 solid. It is placed here provisionally until living examples are 

 obtained.]
