This elongated variety is frequent in the marl and is much 

 larger than its type species, which is small in these gatherings. 

 My specimens differ from Brady's by being more pointed and 

 tapering at the aboral end of the test. This taper soon gives 

 place to a parallel-sided contour and in some cases the shell 

 diminishes in diameter again in the last one or two pairs of 

 chambers. The test has sometimes as many as twenty-four 

 chambers and attains a length of 1/16 inch.
