Plate 48, Figs. 11-13 



Variety differing from the typical form in having two series of alter- 

 nating longitudinal costae, one series extending the full length of the 

 body of the test and ending in acute projections at the base, the other 

 series alternating with the longer ones, shorter and limited to the central 

 portion of the test ; apertural end extended into an elongate slightly taper- 

 ing neck with transverse costae often crossed by the more elongate series 

 of the body of the test.
