 a. Interminatce. — In this division the cells are not bounded by distinct 

 walls, and so far as I have been able to study species of the division it is 

 certain that in the grouping there are a number of variations of cell 

 character that would amply repay the special labour that could be 

 bestowed upon them. This can be done, however, only by those who 

 have access to material from the Maestricht beds. My own knowledge is 

 derived from the Faxoe Limestone species, which are nearly akin to those 

 of Hagenow.
