‘“‘ Nouv. Genre { of Volutidee | Mitro/wmna Bueg., Dautz. et Dollf.”: 
Moll. mar. Roussillon, vol.i, p. 121: Zyrz.—‘' WMitrolumna olivoidea 
Cantraine, sp. (d/itra).”’ 
Upon conchological grounds, nothing being known of the animal, 
I do not think that the small group of shells represented by Jitra 
olivoidea, Cantr., can be placed among the Mitride: the columella 
folds are unlike those of I/tra, and resemble rather the peculiar 
split tooth which is met with in so many Columbellide. If 
CU. lachryma (Rve.) is correctly referred to the Columbellide, 
Cantraine’s Attra olivoidea must accompany it.
