the projection of the minor septa from the inner wall, and from 

 Carcinopliyllum 6, Vaughan, 1 by the absence of a coarsely vesicular 

 peripheral area, by the more strongly marked inner wall, and by the 

 nature of the central area. The character of the inner wall readily 

 distinguishes it from Carcinophyllum kirsopianum, Thomson. 2 



It has not been deemed advisable to assign a new specific name 

 to this form, since it is distinguished from others chiefly by the 

 character of its central area, which is of little value as a diagnostic 

 feature, varying, as it does, in different sections cut from the 

 same specimen.
