FORAMINIFERA. 221 



"Length, I mm." (Bagg.) 



Remarks. — -"Reuss describes this form as being very variable in 

 character, and states that there are two extreme types, which 

 would be considered distinct species were it not for the connecting 

 forms. It is a rare .species at Vincentown, and, we can not state 

 whether the American type is constant or not. The one described 

 agrees very closely with Professor Reuss's figure." (Bagg.)

 (Bagg).
