 acutely angled, the early chambers compressed, the sutures often

 slitlike, in the indentation near the base of the inner border of the 

 chamber. 



Length 1 to 1.5 mm., microspheric proloculum 0.014 mm., megalo- 

 spheric proloculum 0.05 mm. 



Distribution. — This species is widely distributed. It is recorded 

 by Bagg from seven Albatross stations in the vicinity of the Hawaiian 

 Islands, in from 275-865 fathoms. From the Western Pacific I have 

 geen spscimens from Hongkong and from Gaspar Strait. One from 

 "the latter locality occurring with the typical form is shown in fig. 9, 

 where the irregularity of the last-formed chambers gives a very 

 different appearance to the test. Both microspheric and megalo-
