It is difficult to make out the affinities of this peculiar form ; it 

 may be an elongated and curved L. globosa ; but on the whole it seems 

 more nearly allied to L. elongata, with which consequently it is here 

 associated. 



In the Malay Archipelago it is very rare, and has been found only 

 at Station 5 in Area 1, and Station 25 in Area 2. 



The ' Challenger ' specimens were obtained from shallow water off 

 the Cape de Verde Islands ; in material from mid-ocean in the South 

 Atlantic, 2350 fathoms ; and from Station 302, south of Juan 

 Fernandez, 1450 fathoms. Dr. Chaster obtained it from mud under 

 Southport Pier.
