 Inhabits the Eastern Ocean. Linnceus. 



Linnaeus has referred only to Gualter, t. 54. f. G, and says this 

 species " resembles V. scabriuscula, but is narrower, longer, 

 and every where spotted with flesh-colour ; beak entire, and 

 not umbilicated ; outer lip recurved, and crenulated with 

 rounded tubercles." The shell figured by Martini, which 

 Gmelin has followed Schroeter in arranging as the Linnaean 

 V. pertusa, is certainly very different from that species, and 

 was considered by Dr. Solander to be V. Ruffina, with 

 which it accords infinitely better. It is about three inches 

 long, and one third as broad j of a pale reddish yellow co- 

 lour with oblong brown spots.
