Le Jenac. Adanson Senegal, p. 41. t. 2. f. 10. 



La Saiidale. Favaime, i. p. 56l. t.4. lower iig. D. ? 



Martini, i. p. ]60. t. 13. f. 131 and 132. 



Inhabits the coasts of Goree. Adanson. 



Shell five or six lines long, and about four-fifths as broad, of a 

 whitish colour, and is coarse, and transversely wrinkled like 

 a common Oyster-shell ; the inside is very white and glossy. 

 La Sandale, which Favanne considered to be the Linnaean 

 P. Crepidula, appears from the description to be radier 

 larger and thinner, and is said to be sometimes marked near 

 the summit with obsolete longitudinal yellowish brown lines. 



CREPIDULA. 13. Shell oval, flattish, and smooth, 

 with the internal partition flat. 



Patella Crepidula. Linnaus Si/st. Nat. p. 1257. Gmelin, 



p. 3695. 

 Patella porcellana, Var, Martini, i. p. 157. 



Inhabits the Mediterranean, especially on the coasts of Barbary. 

 Linnccus. 



Linnaeus for this species has referred to Gualter, t. 69. f. H, 

 from whence he has derived the name of Crepidula, and to 

 Adanson, 1. 1. f. 1, of which the former is probably at most 

 only a Variety of P. porcellana, and the latter is a shield 

 placed at the tail of its inhabitant, which it only partially 

 covers. In the account of the Museum of the Queen of 

 Sweden, P. Crepidula is described to be white, diaphanous, 

 and flattish, with the internal partition somewhat crescent- 

 shaped and flat. Martini considered it to be a Variety of 

 p. porcellana, and its having been placed by Linnaeus in 

 the following, instead of the present division of the Genus, I 

 imagine must have been wholly accidental.
