 at several stations, but in few numbers.

Test nautiloid, nearly equally biconvex, the dorsal side more con- 

 vex than the ventral; the umbilical region concave on both sides, 

 broad, in face view nearly as broad as the diameter; peripheral border 

 nearly flattened in the later chambers which increase rapidly in 

 width, about eight chambers in the final coil; wall coarsely perforate. 

 The inner border of the chambers often of clear shell material; 

 aperture a narrow curved slit at the ventral side of the chamber, 

 oblique. 



Diameter up to 1.5 mm. 



This species was originally described from the North Atlantic. 

 There are numerous records from other regions given in the list of 

 references above, but it is difficult to be certain except from a study of 

 the original material to determine whether or not they are really the 

 same.
