BULLETIN 104, UNITED STATES NATIONAL MUSEUM 



not seen any Atlantic material equal in size and number of chambers 

 equal to the very large and beautiful specimens that are found at the 

 type locality of Rimini on the Adriatic. 



There are a great many references to this species, but they are not 

 included here as certainly more than a single species is involved, and 

 it is difficult to make sure of the forms unless the original specimens 

 vcan be studied. 



In the West Indian region I have specimens that can be referred 

 here, but from one locality off Biscayne Bay, Fla., where it is common. 

 It never develops the extreme form of typical beccarii. 



From the New England coast I have abundant specimens of a form 

 that seems best referred to beccarii, but also is smaller. In the brackish 

 water of the upper end of Buzzards Bay there is a small form with very 

 peculiar pointed ends to the chambers and with other characters that 

 may prove to be of some distinction, but it is necessary to be sure that 

 this is not due to the conditions under which it lives.
