Trophosome.—Colony small, not over one-half inch in height; stem delicate, sometimes annulated or wavy, irregularly branched; branches given off below the hydrophores, making almost a right angle with the stem; hydrophores strongly flaring, usually reduplicated. Gonosome.—Gonangia oval or ovate, smooth, borne at the base of the branches or below the hydro- phores. Distribution.—On sponge dredged by the Fish Hawk, on which were specimens of Aglaophenia rigida. There was no gonosome; the figure is taken from Hincks. Family LAF(E1D^. Trophosome.—Hydrothecse tubular, margin entire, operculum absent, no diaphragm; hydranth, with conical proboscis. Gonosome.—Gonangia forming a Coppinia mass. The genus Fikllum is the only genus of this family represented in this material. Genus FILELLUM. Trophosome.—Stem a slender stolon, parasitic on other hydroids; hydrothecae, partly adherent, curved outward from the support at the point of separation.

Trophosome.—Stolon creeping over other hydroids, Bryozoa, etc.; hydrotJieca minute, adherent for about half of its length, to the siuface over which the stolon creeps, tlicn abruptly turned away. The free portion is provided with three or more annulations, in the form of ridges, that may be either transverse or oblique. The free portion is more slender than the adherent portion. T
