MELANOPSIS brevis. 
TAB. DXXIII.—fig. 2. 
Spec. Cuar. Ovate, pointed, short; whorls ven- 
tricose, contracted in their upper parts ; aper- 
ture oval; inner lip thick ; callus not very pro- 
minent. 
Mucu 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.
