Babelomurex dalli (Emerson & D' Attilio 1963)

Babelomurex dalli is a species of sea snail, a marine gastropod mollusc in the family Muricidae, the murex snails or rock snails.

Type of larval development: planktotrophic, inferred from multispiral protoconch.

Shell up to ca. 40 mm mm high, solid. Protoconch of ca. 3 whorls normally eroded on adults. Teleoconch of little more than 5 whorls, with conical spire. Spire whorls sharply angulate at shoulder, with loose axial folds and with a conspicuous series of large triangular spines projecting sidewards and upwards from the shoulder over each fold, particularly on the two last whorls; surface of the teleoconch whorls with quite thick spiral cords with densely packed imbricate scales, the intervening spaces narrow and deep. Body whorl profile hardly convex in the area bordering abapically the keel, then smoothly merging into the siphonal canal which terminates in a small fasciole. Aperture gradually tapering towards siphonal canal, rounded adapically; outer lip simple, with the edge markedly notched between cord terminations and with ndistinct spiral grooves reflecting the outer sculpture. Colour white.

Western Atlantic, from Southern Florida to the Bahamas Islands and Guadeloupe; Central North Atlantic, Great Meteor seamount, rare in 300-335 m.
