MELANOPSIS brevis. 
TAB. DXXIII. —Jig. 2. 
Spec. Char. Ovate., pointed^ short ; whorls ven- 
tricose., contracted in their upper parts ; aper- 
ture oval ; inner lip thick ; callus not very pro- 
minent. 
Much resembling several species of Buccinum : the con- 
vexity of its volutions is peculiar for a Melanopsis. Its 
width is about two-thirds its length ; the inner lip is of 
nearly an equal thickness throughout^ affording a strong 
contrast to the species above described. 
Picked up rather plentifully upon the Hampshire coast 
by the Rev. Professor Sedgwick. It has probably fallen 
from the fresh-water series near Hordwell.
