“Theses are at once distinguished by their elongated, spindle-shaped bodies, their branchial apertures placed on the sides of the neck, and their pectoral fins of the ordinary form and position. The symmetrical tail is large and fleshy, furnished with powerful fins, which render it a most efficient agent in progression; the nost is usually conical and pointed, the mouth large, and armed with most formidable, cutting teeth, and the upper surface of the head is frequently furnished with a pair of spiracles, although these apertures are often wanting.” — Goodrich, 1859
