30. Tellina trifasciata. T. testa ovata, Iteviuscula, sanguineo-triradiata, 

 puberugosa. Linn. Syst. Nat. ed. 12. p. 1118. Linn. Gmel. p. 3233. 

 Shell oval, rather smooth, with three red rays, angular division rough. 

 Chem. Conch. 6. pi. 12. f. 114. a. b. 



A roundish, or rather subtriangular, shell, truncated 

 at one end, finely striated transversely, and marked, dis- 

 tinctly, with three red rays, which are deeper, and nar- 

 rower, at the apex, than the margin; the inside is white, 

 and is also rayed, but not so strongly as without ; the 

 lateral teeth are strong. It is about three quarters of 

 an inch long, and rather more than an inch broad. 



Is said to inhabit the European Ocean. 



Is not figure 115 of Chemnitz, quoted by Gmelin as a 

 variety of this shell, a distinct species ? 



Lister's figure, to which Linnaeus has referred for 

 this shell, is the T. Ferroensis ; and Donovan, in pi. 60. 

 of his British Shells, has retained the same misnomer, 

 for the last-mentioned species. The T. trifasciata is not 

 an English shell.
