Description. — Shape, like a very short cylinder set on a hemisphere. 

 The basal portion is very slightly conical, rounded. Very faint costae. 

 V\'ixll thick, vesiculate. Septa thick, in four cycles; those of the fourth 

 cycle fuse to the sides of the third, near the wall. The tirst three cycles 

 reach the columella. Sides granulate: columella vesiculate. Greater 

 diameter, 13 mm.; lesser diameter, 11.3 mm.; height, 11 mm. 



We know but little of this species: only one specimen seems to have 

 been found, and that one is very unsatisfactory. I have referred it to 

 the genus Eupsainniia from the strong resemblance of its septal arrange-
