Plankton-type. .\((ordinii- to llicKi.r, this species has been 

 found in llie ceidral i'acilic, abysmal: according to the above data 

 it occurs in the Northern Atlantic in most cases associated with 

 Sl\ii-|)lankt((n, hnl it seams nevertheless not to be a true Stvli- 

 planklon-form. To jnd.ne from its non Dccurrence in the Atlantic, 

 S. of Uy. it seems as if it derived from the Polar Hasin or X. Pacific, 

 as is probably the case also with many other radiolaria of the 

 Xorthern Atlantic.
