Most of the specimens are of the usual rosy-pink 

 colour. Several have a glassy appearance, the typical 

 colour being absent. I do not think these latter can be 

 a distinct species, as in one instance the earlier chambers 

 shew traces of colour. The spire varies very much in 

 height. In these gatherings this species is far more 

 numerous than any of the Globigerinidae. Frequent.

One or two of the examples found bear short blunt 

 spines, and these are in a more recent condition than the 

 others. Very rare.
