Stromboidea

• Strombidae
  • Persististrombus
    • Persististrombus deperditus (Sowerby, 1840)

Original Description of Strombus deperditus by Sowerby, 1840:

• "Turbinate, tuberculated, and transversely striated; tubercles united by a slight carina gradually increasing in size; lip thickened, produced above into a short pointed lobe. Height 2 1/4 inches, diameter 1 inch 4 lines including the wing."

Locus typicus: Soomrow NE of Jakhau (Juckow), Kutch district (Kachchh), Gujarat State, Western India

Stratum typicum: Lower Miocene

Strombus deperditus Sowerby, 1840, pl. 26, fig. 19

Comment Sowerby, 1840:

• "Much like Strombus Gallus, Linn., and S. bituberculatus, Lam., but the tubercles are of an equal size on the last whorl and not much larger than on the spire. The aperture is not much dilated, so that the wing is rather small. It appears to be a very common shell in the Runn, but perhaps there are several species, as many of the specimens are so firmly attached to the stone, and so much concealed, that the distinguishing marks cannot be traced."

History and Synonymy

1840

Strombus nodosus Sowerby, 1840, pl. 26, fig. 20

Original Description by Sowerby, 1840:

• Turbinate, elongated, tuberculated, and transversely and longitudinally striated; tubercles equal, numerous, prominent, obtuse. Height 1 3/4 inches. Distinguished by rounded tubercles, of which there are about 12 to each whorl - and the elongated spire.

Locus typicus: Soomrow

1854

Strombus deperditus in Haime & d'Archiac, 1854, pl. XXX, fig. 19

1893

Sacco, 1893, p. 5 chose a replacement name for Strombus nodosus Sowerby, 1840: Strombus exnodosus Sacco, 1893

2009

Harzhauser placed Strombus deperditus into Persististrombus as Persististrombus depertitus which is considered as a lapsus calami

Bose et al. 2023 placed Strombus nodosus into the synonymy of Persististrombus deperditus
