The base is roundish, about an inch and a quarter in diameter, 

 and the height of the shell is about three-quarters of an inch ; 

 the outside is greyish yellow, with twelve longitudinal orange 

 lines, and the inside is of a horn-colour. Dr. Turton has 

 changed the name of this species on account of Gmelin's 

 having also given the name of Jamaicensis to another spe- 

 cies ; but as the latter had before received the name of 

 nodosa from Born, the change is unnecessary ; and both 

 Born and Chemnitz have moreover given the name of ra- 

 diata to other shells. 



STELLiFERA. 69. Shell oval, entire, of a blackish 

 brown colour, with narrow longitudinal ribs, 

 and the summit stellated with white.

Chemnitz. 

 This shell appears by the figure to be about two inches long, 

 and an inch and a half broad, and is marked with short ra- 

 diated white stripes at the summit ; the outer surface has 

 narrow longitudinal ribs, crossed with transverse wrinkled 

 striae, and the inside is silvery. Chemnitz says it has been 

 received from London, 'with the name of " the brown and 

 white starred Shield Limpet ;" but I rather doubt whether it 

 is more than a Variety of some neighbouring species, or per- 

 haps of P.J'erruginea. 



FUSCA. 70. Shell conical, obtuse, with about thirty- 

 nine narrow longitudinal ribs ; base ovate, 

 and the margin sliirlitly crenated.
