LEPAS. 69 



The author has several of these shells seated on 

 pieces of cuttle-bone, with clusters of small ones round 

 the bottom of each. A group of them, some of a large 

 size, attached to a piece of rotten wood, is in the pos- 

 session of Mr. Sowerby, and is the specimen repre- 

 sented in the plate.

The testaceous part of this singular species consists 

 of five narrow valves, the two largest of which are 

 placed on the margin of the aperture, and are trian- 

 gular ; the dorsal valve is linear and subcarinated ; the 

 two superior valves are also linear, reflex, and termi- 

 nate in points at the anterior extremity. The membra- 

 nous bag which encloses the animal, is of a greenish 

 colour, with six black longitudinal stripes, three on each 

 side. The pedicle is a continuation of the same, and 

 the whole is about two inches long, and five-eighths of 

 an inch broad. 



Inhabits the Mediterranean and Atlantic ocean. Dr. 

 Solander observed it on the sides of the Endeavour, as 

 he sailed between the Canary Islands and Brasil, and 

 Bosc found it on the ship which carried him from 

 America to Europe.
