 giving t<> man) parts .1 cancellated appearance, one could as well say thal in the upper whorls, 

 the shell is cancellated by granular spirals and concentric riblike striae; moreover the shell lias

the strong peripheral cord, it^ basal pan with two stronger and a great number of finer spiral 

 cords or lira ed bj very fine growthstriae. Aperture subquadrangular, its characters cannot 



t. by the juvénile state; the right margin, which will most probably lx- varicose in 

 the adult shell, is still thin, columellar margin curved, terminating in a sin ui canal, directed 

 towards the left and slightly upturned. 



This new species is very peculiar by its shape and sculpture. I know no species to 

 which it may be allied and think, if it were adult, it would prove to constitute a new section.
