I found this species in great plenty, inhabiting St. John's river in East Florida, from its mouth to Fort Picolata, a distance of one hundred miles, where the water was potable. It seemed to exist equally well where the water was as salt as that of the ocean, and where the intermixture of that condiment could not be detected by the taste.

Página 69 - Shell tapering, horn-color; volutions about seven, slightly wrinkled; spire towards the apex very much eroded, whitish; body with a large obtuse groove, which is obsolete upon the whorls of the spire in consequence of the revolution of the suture on its inferior margin; this arrangement permits the superior margin of the groove only to be seen on the spire, in the form of an obtuse carina on each of the volutions; aperture bluish white within, with one or two obsolete sanguineous lines; labrum slightly...

Length more than one-half of an inch.

Página 61 - Shell conic, subumbilicate, dark horn-colored, generally incrusted with a blackish irregular covering on the spire, and sometimes on the body, which completely obscures the obsoletely wrinkled epidermis; aperture ovate-orbicular; suture impressed.

Animal longer than the breadth of the shell, acute behind, above granulated and blackish* beneath, and each side, white. This we found in the orange groves of Mr. Fatio, on the river St. John, East Florida; it is usually covered with a black, earthy coat, which is probably collected and detained by the hairs. When unincumbered with this vesture, the shell is of a horn colour. It is by no means so common as the preceding species....
Página 47 - Animal bluish-white beneath, with orange clouds each side of the mouth: above pale orange, shaded with dusky and banded with numerous black interrupted lines; mouth advanced into a rostrum as long as the tentacula, which are darker at base, and setaceous; foot with an undulated outline. Var. A. Shell destitute of the rufous bands.
