The only record for this species in all the material examined from 

 the region is off Singapore in 13 fathoms (23 meters), U.S.N.M. 

 No. 15661. It was typical, however. 



The Challenger specimens were from off the Bli Islands, 129 fathoms 

 (236 meters), and off the west coast of New Zealand in 275 fathoms 

 (503 meters). They had the peculiar initial chamber with a basal 

 spine and the later chambers pyriform. A similar specimen was 

 found off the Galapagos Islands in deep water. The Atlantic material 

 recorded from about the British Isles does not seem from the pub- 

 lished figures to be typical.
