[37] Many authors (Poli, Montagu, &c.,) have doubted from the strangely mistaken description, viz., “ore octovalvi dentato,” whether this species could be the Lepas aurita of Linnæus. But in the Linnean Society, there is a proof plate from Ellis’s “Account of several rare Species of Barnacles,” in ‘Phil. Trans.,’ 1758, with an excellent figure of the C. aurita, and on the margin in Linnæus’s handwriting is the name Lepas aurita.
C. capitulo duobus tubularibus quasi-auribus instructo, pone terga rudimentalia (sæpe nulla) positis: scutis bilobatis: carinâ nullâ, aut omnino rudimentali: pedunculo longo, a capitulo distincte separato.
Capitulum with two tubular ear-like appendages, seated behind the rudimentary and often absent terga; scuta bilobed; carina absent, or quite rudimentary; peduncle long, distinctly separated from the capitulum.
Filaments attached to the pedicels of the second cirrus; two upper spines of the maxillæ pectinated.
Hab.—Mundane; extremely common. On ships’ bottoms from all parts of the world. Arctic Sea. Greenland. Pacific Ocean. Often attached to Coronulæ on Whales. On slow-moving fish, according to Dr. A. Gould. Often associated with C. virgata, and [Lepas anatifera], L. Hillii, and L. anserifera.
