"Shell ovate, yellowish, beneath rufous; spire short, thick, obtuse, chestnut; striae on the pillar obsolete. This is a recent species, hitherto undescribed, and so closely does it resemble the figure of A. glandiformis, given at pl. 393. f. 7. of the Ency. Meth. that it might be almost assimilated to that shell, but for the danger of uniting recent and fossil species without very minute examination; this I am at present unable to do, not having a specimen of Glandiformis in my own collection. The spire of the A. obtusa is little more than half the length of the aperture, and is rendered very thick and almost shapeless, by a coating of enamel, which also forms a mass on the upper angle of the aperture; this enamel is likewise continued as a belt across the shoulder of the body whorl; the base of the shell has two thickened belts; the upper of which is chestnut, and margined above by a narrow white band, in which are two slender grooved lines; the middle of the body whorl is pale yellowish above, and deep chestnut beneath; the shoulder belt and the spire are also chestnut, with two white bands; the tip of the spire, the aperture, and the callosity above it, are pure white; base of the pillar but slightly thickened, and faintly striated by two grooves; outer lip one-toothed.".
