Although resembling Bulimina in some ways, its affinities seem 

 closer to Textularia and related genera. The aperture is not usually 

 asymmetrical to any extent, as claimed by Brady. 



A study of the microspherie and megalospheric forms in the differ- 

 ent species should be made to determine whether or not there are 

 coiled chambers in the early development of the microspherie form. 



The species which exhibit a tendency toward a uniserial condition 

 have been referred by some authors to Bifarina. The last two 

 species in the present series may be so placed.
