Bullata - Shell Description

Shell Description

The shells of species in this genus are moderately large to very large, range size from 14 mm (Bullata largillieri, smallest species of Bullata) to 97.9 mm (largest specimen known of Bullata bullata). (pl I)

The shell color is a yellowish-orange to orange- or pinkish-brown, spirally banded (pl II) or with white spots (pl III). The lip is pink, yellow, or orange, darker than shell color (pl IV).

The shell surface is smooth and glossy.

The shape is elliptical to oblong or obovate, moderately to strongly shouldered (pl V bottom). The spire is immersed or near so (pl V top). The aperture is narrow to moderately broad, wider anteriorly. The lip is moderately strongly thickened, weakly to strongly denticulate in adults, with a distinct external varix. A siphonal notch is present but a posterior notch is absent. The parietal callusing is weakly to strongly developed, especially posteriorly, and is absent in type species. The columella has four continuous plications occupying less than half the aperture length. The internal whorls are unmodified. (pl VI/VII)

Famous quotes containing the words description and/or shell:

    The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St Paul’s, like the editions of Balbec and Palmyra.
    Horace Walpole (1717–1797)

    I was even more surprised at the power of the waves, exhibited on this shattered fragment, than I had been at the sight of the smaller fragments before. The largest timbers and iron braces were broken superfluously, and I saw that no material could withstand the power of the waves; that iron must go to pieces in such a case, and an iron vessel would be cracked up like an egg- shell on the rocks.
    Henry David Thoreau (1817–1862)
