Although moderately plentiful and widely distributed in the 

 Malay Archipelago, the examples are small and composed of but 

 few chambers. 



Brady says of this form that it is less common than the type 

 (P. lactca), but it has a similar wide area of distribution. Eg<j;er 

 records it from West Africa, 371 fathoms; and Flint has the 

 fistulose variety from the North Atlantic, from off the coast of 

 Brazil, and from the Gulf of Mexico, 671 to 1781 fathoms.

This variety is better represented than the type, it is rather 

 more abundant, and widely distributed, and the examples are less 

 feeble. 



Brady says, " This form has been met with at two points in the 

 North Atlantic, west of Ireland, depth 808 fathoms and 1443. 

 fathoms respectively ; and at Station 146, about midway between . 

 the Cape of Good Hope and Kerguelen Island, 1375 fathoms."
