The operculum is horny, long, and narrow, resting upon a thin tail. Pierocerag, Lam., have the mar- gin of the full-grown shell divided into long, slender digitations, varying in number ac- cording to the species. The animal is the same as in Strombus. Other Strombusidœ have the sinus con- tiguous to the siphon. These are the Ros- tellaria, Lam. They have generally a second canal mounting up the spire, and formed by the external lip, and by a continuation of the columella. In some of them the lip is digitated. Their animal resembles that of the Muricida; ; but the operculum is very small. Others have merely denticulations on the lip : their canal is long and straight. Others have the margin entire and plane ; and these are the Hippocrenes, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Cuvier, Georges, baron, 1769-1832; McMurtrie, Henry, 1793-1865; Metcalf Collection (North Carolina State University).
