Species / Lobatus Galliformis

Lobatus Galliformis

Stromboidea


Original description of Strombus galliformis by Pilsbry & Johnson, 1917, p. 170:

  • "The spire is high, with sculpture of axial riblets and inconspicuous varices on the earliest whorls, changing to short tubercles on the last four, the penult whorl having two low, massive varices. Whorls of the spire having unequal spiral striae. The last whorl has a smooth shoulder in front, three high tubercles on the back, the central one largest; the whole surface having widely spaced spiral ridges and fine, very weak, spiral striae. Lip produced upward in an angle, smooth within; no entering wrinkles on the posterior end of columellar lip."

Stratum typicum: Oligocene (?)

Holotype: Academy of Natural Sciences Philadelphia Nr. 2582

Dimensions: "Length 100, diam. 66 mm.; 9 1/2 whorls."

Comment Pilsbry & Johnson, 1917, p. 170:

  • "In the recent S. gallus the lip is far more produced upward ami it spreads on the left side above the shoulder; the spiral ridges on the back are coarser, and the tubercles at the shoulder more numerous. The new form is more like S. peruvianus in form of the lip, but that species has the throat conspicuously rugose."

Pilsbry & Johnson, 1917 are citing:

  • Strombus bituberculatus Lam., in part, Gabb, Tr. Am. Philos. Soc., XV, 1873, p. 233. Not of Lamarck.

History and Synonymy

1922

Pilsbry, 1922, p. 366:

  • "Compare S. maoensis Maury, which may be the same. It has a shorter spire, and the lip appears to be unknown."
