they are clothed with a roughish epidermis, which is produced 

 into short hairs arranged in spiral series and also in oblique 

 rows upon the lines of growth. When the epidermis is 

 removed only faint indications of spiral strias are observable.

 a corneous nucleus, where it is slightly concave, and consists 

 of seven or eight obliquely striated volutions. It is thick and 

 deeply concave between the outer shelly margin and the inner 

 corneous layer, which is of a bright red tint.

This handsome species is a little larger tiian P. ottonisy 

 Dohrn, from i\Iiiulanao, and of a darker colour; the penultimate

 broader in the present species. The operculum is thin, of a 

 bronzy-yellow tint, and consists of about eight whorls.
