Test in the early stages planispiral, at least in the micro-

 Orbitolites (part) of authors (not Lamarck). 



Test discoid, planispiral in the early stages at least of the 

 microspheric form, later annular, completely divided into 

 chamberlets; typically in a single layer, those of each annular 

 chamber communicating with the adjacent ones as with those 

 of the preceding and succeeding annular chambers; wall 

 imperforate except in the very earliest chambers; apertures in
