Siphonophoral (sif on of or a)

[NL. (Brandt, 1836), fem. sing. of * siphonophorus, many of which are common to Europe and America, as the grain plant-louse, S. avenæ, and the rose plant-louse, S. rosæ. Siphonophora2 (si-fo-nof'ō-rä), n. pl. [NL., neut. pl. of * siphonophorus: see Siphonophora1.] Oceanic hydrozoans, a subcla of Hydrozoa or an order of Hydro med usæ, containing free pelagie forms in which hydriform persons and sterile medusiform persons (in one family only the former) are united in colonies or aggregates under many special modifications, but definite and constant in each instance. The medusiform or sexual persons are usually only in the form of sporosacs, but sometimes are matured before they are set free from the colony. The structure is e entially a hollow stem or stock, budding into many different kinds of ap pendages, representing modified hydrantes driform or undeveloped med us i forms. appendages which a siphonophoran may or does have are the float, pneumatophore or pneuma to cyst, which may be absent or replaced by an inflation of the whole stem, the soma to cyst, as in the Portuguese man-of-war; the swimming-bell or nectocalyx; the hydrophyllium, covering some of the other parts; the dactylozoöid, or tentaculiform person; the gastrozoöid or nutritive person, which may be highly differentiated into oral, pharyngeal, gastric, and basal parts, which latter may bear long tentacles; and the sexual persons, medusiform buds proper, or gonophores. The arrangement of these elements is very diverse in the different forms of the order. The Siphonophora are sometimes divided into two orders, Calycophora and Phy sophora, or into four suborders.
