*) T. sat parva, crassa, solida, imperforata, elongato-conica, angusta, subventricosa, costis longitudinalibus crassis 
et nodosis impressa. Spira elongato conica, apice acuto. Sutura plus minusve profunda, marginata. Anfractus embryo- 
nales nitidi ; sequentes sat lente erescentes, eonvexi, longitudinaliter costati, eostis erassis minime prominulis, ad mediam 
partem subnodosis, aliquando in varices mutatis et transversim striis punctatis tenuissimis ornati. Anfr. ultimus spira 
minor, basi convexus, disco saepissime obsoletissimo, punetato munitus. Apertura ovalis. Peristoma duplex, internum 
erassiusculum, vix prominulum, eontinuum, externum erassum, postice interruptum, punetatum et ad labrum varice ultima 
eonstitutum. — Typus: Sc. bicarinata, Sow. foss. — de Boury, in: Bull. Soc. Mal. ital. 1889 XIV p. 168.
