" Test 2-6"' elongate, small, lancet-shaped, at the lower end 

 much elongated, above pointed, broadest at or above the centre. 

 From the centre out to the marginal borders decreasing. Nu- 

 merous (15-25) very small chambers, which are separated by 

 proportionally broad roof-shaped sloping edges. These are inter- 

 rupted in the centre by a longitudinal furrow which is smaller 

 below, and moreover striated by more fine short lateral furrows, 

 which nevertheless are not continued into the spaces between the 

 edges. The lowest chamber very small, quite spherical, on every 

 side provided with thin sharp longitudinal ribs and a short point 

 on the base. The tolerably sharp lateral margin is continued 

 over the first chamber to the end of the shell. "^-Reuss, loc. cit.
