Fusus colosseus and proboscidalis, Lam., are two of the 
largest living gasteropods. Jusus (chrysodomus) antiquus, called 
the red-whelk on the coasts of the Channel, and ‘‘ buckie”’ in 
Scotland, is extensively dredged for the markets, being more 
esteemed than the buccinwm. It is the “roaring buckie,” in 
which the sound of the sea may always be heard. In the 
Zetland cottages it is suspended horizontally, and used for a 
lamp; the cavity containing the oil, and the canal the wick. 
(Fleming.) The reversed variety (F. contrarius, Sby.) is found 
in the Mediterranean, and on the coast of Spain; it abounds in 
the pliocene tertiary (crag) of Essex. The fusus deformis, a 
similar species, found off Spitzbergen, is always reversed. 
Famity IIl.—-Buccinina. 
Shell notched in front; or with the canal abruptly reflected, 
producing a kind of yarix on the front of the shell. 
Animal similar to mvrex; lingual ribbon long and linear
