MUREX sexdentatus. 
TAB. CCCCX1 .—Jig. 3. 
Spec. Char. Ovate acuminated, costated, lon- 
gitudinally striated, transversely carinated ; 
whorls convex ; aperture elongated with 
5 or 6 teeth within its outer lip. 
.Much resembling; the last, but the whole surface is 
marked with elevated sharp striae, that are more crowded, 
but hardly more prominent, upon the swelled sutures ; 
the thickened outer lip has about 6 obtuse teeth within 
it, in place of the many lamellar ones of the M. defos- 
sus ; the last whorl is also more conical, and the aper- 
ture squareish. 
Brought from Colwell Bay, on the Isle of Wight, 
by Professor Sedgwick, who pointed it out as distinct 
from several other shells with which it had been con- 
founded.
