Thomas Hincks, B.A. The species that are briefly charactei'ized in the following paper will be more fully described and figured in the general history of the British Hydroid Zoophytes on which I am now engaged, and which I hope will soon be ready for the press. Subkingdom CCELENTERATA. Class HYDROZOA. Order HYDROIDA. Suborder TUBULARIDA. Family Corjmidse. Genus Coryne. C. vermicularis, n. sp. Zoophyte forming dense shrubby tufts ; hydrocaulus smooth, branched dichotomously, of a very light straw-colour and deli-cate texture, wavy, annulated, especially towards the base, the branches and upper portions of the stem often smooth or slightly wrinkled ; polypites of great length (about ^ inch when mature), stout, almost cylindrical for half their length, when ex-tended, and then tapering off very gradually towards the oral extremity ; tentacles in irregular and very distant whorls, rather stout, with large capitula, about twenty-five in number. Repro-ductive sacs borne at the base of the tentacles over the lower part of the body, spherical, shortly stalked. Height of the tufts about | inch. Distinguished by the great size and worm-like appearance of its polypites and the sparing distribution of the tentacles over the body. Hab. Shetland, from deep water.
