“ The species yet discovered are few, and hence we yet can only trace three types of form; the first evidently representing Mitra, and the third, probably, typifying Conohelix. M. Olivaria Lam., which truly belongs to this genus, may, perhaps, be only a modification of the 2nd type, to which our present species strictly belongs. The representation of this group among the Volutes, will be found in Voluta Zebra and its allies.Mitrella fusca is small, and of great rarity; our own specimen, beautifully perfect, is the only one we have yet seen. ”
