It is not possible to verify whether this taxon carries teeth on the outer lip or not. According to Wenz (1943: p. 1264) the genus should be characterized by a slightly oblique protoconch and a sharply cut distal end of the siphonal canal. Neither feature is observed in the present taxon, which otherwise is well in accord with the diagnostic features of this genus.
