Test planispiral, bilaterally symmetrical, entirely involute, except 

 that the umbilici are deeply excavated, periphery very broadly 

 rounded, entire; chambers 8 to 10 in the last-formed coil of the same 

 general shape, not inflated; sutures flush with the surface, generally 

 Umbate, fusing along the umbilicus to form a slight thickening about 

 it but not raised above the surface; wall smooth, coarsely perforate; 

 aperture sUtHke, between the base of the apertural face and the pre- 

 vious coil, apertural face broad and low. Length, 0.6 mm; thickness, 

 0.4 mm. 



This is essentially a deep-water species, and all the specimens 

 obtained were from Albatross stations, data for which are given in 

 Table 22.
