Creriraium? Witcneiu, Lyc. Tab. XLIV, fig. 7. 
Testa minuta subcylindrica, elongata, anfractibus (5—6) subconvevis altis, suturis valde 
impressis, costis (circa 15) depressis subrectis, superne distinctis, inferne evanescentibus 
apertura ovata, labro eaterno simplict. 
Shell minute, subcylindrical, lengthened; volutions (5—6) high, rather convex, the 
sutures depressed and strongly defined ; costee (about 15 to a volution) depressed, distinct 
at the upper and vanishing towards the lower part of each volution; the aperture is of 
moderate size, ovate, the lips rather thickened.

CreritHIuM ? puLcHRUM, Lyc. Tab. XLIV, fig. 4. 
Testa parva, crassa, turrito-subulata, anfractibus (8) convexis, suturis valde impressis, 
costis transversis, obliquis, magnis (circa 12 in ambitu), linets longitudinalibus decussatis, 
apertura parva ovata, canali nullo, 
Shell small, thick, elongately turreted; volutions 8, convex, the sutures deeply im- 
pressed ; transverse coste about 12 to each volution, oblique, large, decussated, and 
rendered nodulous by six narrow encircling lines; aperture ovate, rather contracted; no 
canal. 
Allied to Cerithium costellatum, Desh., from which it differs in having fewer volutions, 
and in possessing encircling lines. C. dud/imoides, Desh., with a similar general figure, has 
the costee smaller, fewer, and perpendicular.
