specimens from the Middle Lias of France, and by a remarkably fine 
specimen from Lyme Kegis. The latter retains the greater portion 
of the test, perfectly preserved. The umbilicus is not so open as that 
of jS\ intermedins^ -with which the present species has been com- 
pared ; the specimen figured by Lumortier, wantiug the shell in the 
umbilical region, has the appearance of being more open in that 
situation than it really is when the test is present.
