It may be that this form after all — according to the authority of Messrs. Parkee 

 and Jones — ought to be considered as a variety of Heterostomella aculeata Ehrenb.; 

 but as there is a great difference in the structure of the test it seems reasonable 

 to distinguish it as species. In transmitted light our species is amber-coloured, very 

 delicate and without pores, so that one would be disposed to refer it to the Miliolina- 

 group. 



A single specimen only has been met with on the chalk-bottom, in a pigmy state.
