gated on tlie upper parts, or sometimes cancellated, or covered with 

 reticulated wrinkles with elevated interspaces, smoother near the edge 

 of base, where it is radiated with conspicuous dark lines of unequal 

 length, corresponding to internal chambers, and alternating with nar- 

 rower liglit lines, corresponding to the lamella? ; the edge crenulated. 

 Cinclidie at about '25 or -'SO inch from the edge of the base, forming a 

 circle of about 24, rather distant, conspicuous, perforated verrucae, 

 often with another more or less complete circle a short distance below, 

 in which the cinclidsB correspond in position with the upper ones, but 

 appear to be smaller. Acontia pink, long, and line, protruded freely 

 both from the month and cinclid;i3. Tentacles slender, of moderate 

 length, " arranged in four series (24-24-96)."
