Original description:
The protoconch is composed of three elongate whorls, the initial portion being slightly inflated, whilst the anterior turns are obtusely carinate. The shell is narrow and elongate. It contains ten whorls, slightly convex, and has several bold, irregular, spiral threads or ridges, rather rugose where crossed by growth lines, and somewhat granulated in the neighbourhood of the sinus. The siphonal canal is long, slender, and twisted. The outer lip is serrate. The sinus is large and deep, and situated some distance from the suture.Harris (1897), Catalogue of Tertiary Mollusca in the Department of Geology, British Museum (Natural History) part I p. 39 pl. 2 10 a-d
