Frequent, occurring in two distinct forms, one very small and hyaline, the 
other much larger (up to three times the size) and with a mutt surface. 
The second form presents the same external characteristics even in the 
immature condition, and we are unable to offer any explanation of this 
condition. They are not dead or eroded shells.

Rare. The specimens are small,, with extremely pronounced, i-aised, 
limbate sutures. Immature specimens are hardly distinguishable from the 
figure of Cassidulina elegans Sidebottom (S. 1910, J. Quekett Micr. 01. 
ser. 2, vol. xi. p. 106, pi. 4. fig. 1), to which, perhaps, we should have 
ascribed them in the absence of the mature and more typical individuals.
