are somewhat, tliougli not very greatly, elevated above the wall, and are 

 entire; there are no dentations, and if crenations are present they are very 

 faint. The inner septal edges are thickened and liave a decided tendency 

 to fuse laterally. The septal faces are covered b}^ many small granulations, 

 which are arranged in iiiore or less regular curves parallel to the upper 

 septal margin, and possess also a linear arrangement. The inferred trabecu- 

 lar constitution is the same as in Sp. nanus. The columella is lamellar, but 

 is peculiar in that it terminates above in about six elongated knots, which are 

 arranged with their longer axes in the plane of the longer diameter of the 

 calice. The calicular fossa is not very deep.

This species can be easily distinguished from Sp. nanus by (1) the tend- 

 ency of the costaj to be granular, (2) the ujij^er termination of the columella 

 (c£ figures), and (3) its larger size, though there may be an occasional over- 

 grown specimen of »S|/;. »(^n/(f.s-.
