This cirrhiped which, at Concepçion de Chile, is frequently found of a larger size than 5½ inches long and 3½ in diameter, forms a very common and highly esteemed food of the natives, by whom it is called Pico, from the acuminated processes of the two posterior opercular valves. The anterior and posterior opercular valves, when in contact, present some resemblance to a parrot's beak, whence Molina's name. It is also found very abundantly at Valdivia and at Calbuco, near the north end of the island of Chilóe. It occurs in large bunches, and presents somewhat of a cactus-like appearance. The parent is covered by its progeny, so that large branches are found composed of from fifty to one hundred distinct individuals, each of which becomes in its turn the foundation of another colony. One specimen in the possession of my friend W. J. Broderip, Esq., consists of a numerous group based on two large individuals. They are collected by being chopped off with a hatchet. At Concepçion, where they are found of larger size than to the southward, they are principally procured at the Island of Quiriquina, which lies across the entrance of the bay; whence they are exported in large quantities to Valparaiso and Santiago de Chile, where they are considered as a great delicacy, and indeed with some justice, for the flesh equals in richness and delicacy that of the crab, which, when boiled and eaten cold, it very much resembles.
