certain tertiary species, some of which occur in England, in the 

 Bracklesham and Barton beds, or the London Clay. Such are 

 P. cW/AYz Desh. and P. fiisurata Desh., both formerly considered as 

 pertaining to Bucchiuiii. I am much indebted to Mr. Edgar A. Smith 

 for aiding me in the elucidation of the synonymy of this species.

 aliter siil^plicata, trausversim creberrinie striata, striis con/ertis,

 Hab., Africa (Mus. Cuming). Three examples, now in Mus. Brit. 

 A small, somewhat obscure species; locality probably West African. 

 As suggested by Tryon^ it may be but a young form of the preceding. 

 It is, however, s[)irally striate throughout, although these striae might 

 become obsolete at maturity. Operculum distinctly Purpuroid. When 

 the epidermis is removed, the substance of the shell, smooth and shiny, 

 is found usually to be of a carneous or ochre hue. It occasionally is 

 of a pale brown, fading into white.
