V. testd oblongo-ovatd, costatd, postice levi, antice transversim sulcata; anfractibus 
duplict serie spinarum dentiformium donatis ; costis numerosis, lateraliter compressis, fere 
ad basin tendentibus, postice tuberculatis et in mucrones primam seriem spinarum forman- 
tes, prolongatis ; sulcis transversis latis, profundis, costas fortiter decussantibus ; spatio 
inter series spinarum concavo ; labro tenui, simplict ; columelld uniplicata. 
Shell ovate-oblong, armed with two rows of short, upright, pointed spines, ribbed, 
smooth behind, transversely furrowed in front; ribs numerous, thick, angular, com- 
pressed sideways toward the aperture and terminating posteriorly in sharp conical 
points forming the front row of spines. The ends of the ribs, immediately in front of 
the spines present a rounded depression at the anterior margin of which they rise into 
small tubercles. The transverse furrows are wide and deep, strongly decussating the 
ribs. The posterior margins of the whorls, between the rows of spines, are sunken and 
concave ; the outer lip is thin, sharp-edged, smooth within? ; the columella presents a 
single very oblique fold. 
The sharp erect conical spines and the prominent ribs, deeply cut by the transverse 
furrows are characters so distinct, that I am unwilling not to record the species, although 
the only specimen I possess has lost the spire and is otherwise imperfect. It appears 
to be a young shell, and the actual character of the outer lip cannot be stated with 
certainty ; there are not any traces of the columellar lip preserved. 
Size.—Axis, (without the spire) 3 inch, nearly ; diameter, rather less than 3-10ths 
of an inch. 
Locality—Bracklesham Bay ; very rare.

V. testa turbinatd, costata, postice levi, antice transversim sulcatd ; spird elevatd, apice 
acuto ; costis sub-distantibus, vie ad sulcos tendentibus, postice in tuberculos lateraliter com- 
pressos elevatis, deinde bind serie brevium spinarum coronatis ; apertura elongato-ovali, 
angustd, postice sub-canaliculatd, antice late emarginatd ; labro intis incrassato, ad marginem 
acuto ; labio effuso ; columella recta, biplicata. 
Shell turbinate, ribbed, transversely furrowed at the base, smooth behind; spire 
elevated, pointed, with a small conical apex; ribs rather distant, extending scarcely 
beyond the middle of the whorls, rising at the posterior extremities into large, prominent, 
laterally compressed tubercles, and crowned with a single row of short, erect, tooth-like 
spines. The sutural margin is depressed and bordered by a raised line, which occa- 
sionally rises into minute pointed tubercles; aperture of a lengthened oval form,
