History and Synonymy


Original Description of Rostellaria cancellata Forbes, 1846, p. 128:

  • "R. testa conica, spira longa, anfractibus 6, rotundatis, bicarinatis, costis longitudinalibus spiralibusque distantibus reticulatis."
  • Dimensions: "Lenght 0 11/12 inch. Spire 1/2 inch. Breadth with lip 1/1 inch.
  • "A young shell, but easily distinguished by its wide window-like sculpture, formed by the distant spiral ribs crossing other equally distant longitudinal ones. The spire is much produced."
  • "Locality, Pondicherry."

Comment: Although Forbes pointed on p. 128 under the description to pl. 13, fig. 18, he used a different name on the plate and in the index.

Aporrhais securifera in Stoliczka, 1867, pl. II, fig. 2, 2a, 3, 4

Stoliczka, 1867, p. 119:

  • "Forbes did not describe a single Fusus from South India, but numerous mistaken species have been attributed to him by subsequent correctors. I shall notice them briefly and append some remarks with regard to the alterations, which have been thought necessary. ... 2. Rostellaria cancellata, Forbes, loc. cit. p. 128, [Rostellaria] cancellifera, ibid. Pl. 13, Fig. 18 = Fusus subcancellatus, D'Orb. could not be traced, but the fragment certainly belongs to an Apporrhais[sic] or Alaria, never to a Fusus, nor to any species of the Fusidae. It may be a fragmentary specimen of the upper whorls of Ap. securifera, Forbes (vide p. 28, Pl. II, Figs. 2-3)."
