The test, although very flexible, is firm and suffi- 

 ciently elastic to retain its shape when the plasma, as 

 occasionally happens, does not entirely fill it; when 

 viewed in transverse section its thickness is denoted 

 by the double contour-line and its structure is indicated 

 by the numerous transverse striations which probably 

 represent the margins of small discs or pellets incor- 

 porated in it as is the case with most of the other 

 members of the genus. 



The anterior portion of the plasma is usually crowded 

 with vacuoles, many of them of large size ; when the 

 aperture is completely closed these serve to indicate 

 which is the buccal extremity.
