FIG. 11. II. 

 PATELLA PARVA. 



SMALL LIMPET, 

 SPECIFIC CHARACTER. 



Shell small, entire, without gloss, whitish, faintly rayed with red. 



Patella Parva: Integra, parva, sublsevis, albescens radiis ruben- 

 tibus. Da Costa Br. Conch, p. 7. sp. 3. 



Da Costa considers this as a nondescript species ; he received 

 several specimens of it from the coasts of Dorsetshire, but never 

 from any other of the British shores, and therefore proposes it as a 

 scarce Shell. 



It is rather larger than a pea, thin, and semipellucid ; of a depressed 

 conic shape, and the vertex inclining very much to one side. The 

 inside is whitish, outside the same, with a few longitudinal rays of 

 pale red, or purplish brown.
