This species differs from Turris thurstonensis (Weaver, 1916) in the fact that in all specimens of the species there are two constant revolving ribs between the suture and the angulated portion of the whorls. The intercalary threads are also absent between the revolving threads. The adult specimens of the species are smaller than in the case of Turris thurstonensis.K. E. Van Winkle. 1918.
