fleeted; back valve strongly carinate or ribbed longitudi¬ 
nally at the sides, and rather rounded in the middle, form¬ 
ing an obtuse angle towards the bottom, the outer point of 
which is produced and blunt, whence it becomes gradually- 
dilated to the end, which extends to the termination of the 
other valves and is rounded and a little reflected, the up¬ 
per end or point reaching a little more than half way up 
the shell : stalk very short, and almost entirely covered 
with the reflected ends of the lower valves : length three 
quarters of an inch ; breadth more than half an inch.

Shell somewhat oblong, gradually sloping into the stalk, 
obliquely truncate at top, fleshy, flattish, with five small 
white testaceous valves j the two upper ones linear, run- 
mag rather obliquely j the two lower ones linear, with a 
strong hook-like process in the middle of each, projecting 
inwardly, and curving a little upwards to a point ; the back 
valve linear, gibbous in the middle, extending at top to the 
termination of the upper-pair, where they meet and form a 
h projecting
