142 FORAMINIFERA OF THE CRAG. 



The Textilarise are so very variable in their growth, forming vesicular, quad- 

 rate, or flattened chambers, and arranging them sometimes quite regularly and at 

 other times with a want of neatness, that there may be almost as many names for 

 them as there are groups of more or less similar individuals. 



Specimens having sandy shell-tissue were grouped as I'lecaniuin by von Reuss 

 (' Sitzungsb. k. Akad. Wiss. Wien,' vol. xliv, 1861, p. 383).
