This small species has been referred to californiensis as a sub variety, 

 and, in the collection, has found a place as a variety of arrosa or exarata, 

 with which it has little affinity. A series of forty-three specimens, 

 collected at different times and by different people, indicates very uni- 

 form size (max. diam. 18, min. diam. 15, alt. 11 mm.) ; the whorls range 

 from 5 to 5i; the suture is deep, the umbilicus deep and subcylindric; 

 the lip not "much reflected, but in adults unusually thick for the size of 

 the shell, especially near the pillar, and the deposit when fresh is of a 

 pinkish tint; the brown baud is narrow, the paler margin not conspicu- 

 ous, and the suture revolves at its lower edge. The sculpture is entirely 

 different from that of ramentosa, which has the granulations obliquely 

 spaced by ungrauulated inte-rvals, forming a distinct pattern, and is
