The name Cerithiopsis clathrata A. Adams in H. Adams & A. Adams, 1853 is a nomen nudum. Adams
later named a Cerithium clathratum A. Adams, 1855 which was placed in Potamides (Pirenella) by Tryon
(1887: 165–166).
Tryon (pp. 172–173) listed and figured Cerithiopsis angasi Semper [sic; = Schmeltz] with reference only
to Schmeltz, noting that it had been “described by Angas under the preoccupied name of C. clathrata.” There
is nothing in Tryon, or elsewhere, to indicate why Cerithiopsis clathrata Angas, 1871 (p. 16, pl. 1, fig. 12) is
preoccupied by any other usage in Cerithiopsis.

Schmeltz listings in the synonymy of Mitra michaui Crosse & Fischer, 1864. It was separated again, and the
name made available, “ex Schmeltz Mss.” as Mitra (Costellaria) deshayesi var. dunkeri Dautzenberg &
Bouge, 1922: 201.
