cords as the interstices and the excavation, is covered with regular spiral rows of small granules, 

 giving to many parts a cancellated appearance, one could as well say that in the upper whorls, 

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

 on the lower whorls, especially of the smaller specimen, indistinct ribs; last whorl carinated by 

 the strong peripheral cord, its basal part with two stronger and a great number of finer spiral 

 cords or lirae, crossed by very fine growth- striae. Aperture subquadrangular, its characters cannot 

 be made out, by the juvenile state; the right margin, which will most probably be varicose in 

 the adult shell, is still thin, columellar margin curved, terminating in a short 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.
