Distribution. — The typical form of this species, that with the coil 

 decidedly open, is found in abundance in the Caribbean and generally 

 in the path of the Gulf Stream. Farther north there are bottom 

 specimens which have the more involute character of the variety I 

 have described as var. involuta? 



The typical form develops to a considerable size and it is possible 

 in some specimens to see between the last whorl and the preceding 

 one in side view. In the early development the test is somewhat 

 trochoid, but this soon gives rise to a planospiral arrangement of the 



chambers.
