This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 Excerpt: ...not present. This species bears a very close resemblance, in many respects, to Calycella syringa, Linn. Found near low water. Family-LAFOEIML Lafo'ia dumosa, Fleming. 1 dry specimen, 1 specimen in box. SPECIMEns This hydroid is found either 29, SO. twining up some other species or over running other objects, and in this, the creeping condition, the stem is simple (single). In another phase, the stem is erect and branching, in which case it is compound, as are also the branches. This habit of producing a compound stem is apparently induced by the need of stiffening and support for the zoophyte. The receptacles are tubular and somewhat curved. There is a short pedicel, and in the upright form the receptacles are arranged around the axis. Capsules not present. This species is common in deep water. Two other species, L. pocillum and L parrnla, Hincks, have been found locally. stem is creeping and reticulate, and is set in a Filellum serpent, HaanlL SPECIMEn 31. 1 specimen. The character of this species is similar to that of the last, but the horny crust. The receptacles are curved, bearing some resemblance in shape to the old-fashioned powder horn. The lower half of the receptacle is adherent to the crust. F. serpens is very common on the stems of other hydroids, rarely on shells. Family--COPPINIIM. Coppinia arcta, Daiyeii. (fig. 12.) 1 dry specimen in box. Specimen The receptacles are long, tubular, 32. and curved, and are set in a horny cellular crust which invests the tubes of other hydroids. A comparison of sections of this crust with that of Hydractinia, and the stem of Antennularia ramosa, and others, will be found instructive. Common in the coralline zone. Family--HALECIIDE. Halecium hcUecinum, Linweus. 1 specimen dry, of exceptionally fine growth. Speci...
