Variety differing from the typical in the more nearly spherical body

Lagena laevis (Montagu), var. 

 Plate 45, Fig. 18 



The figured specimen seems related to L. laevis (Montagu) and in 

 some respects to var. baggi Cushman and Gray. The basal end, however, 

 is broad and has a peculiar spinose ornamentation. The form is here 

 figured for reference until more specimens show its true relationships.
