Archive image from page 47 of The Danish Ingolf-expedition (1898). The Danish Ingolf-expedition danishingolfexpe1517dani Year: 1898 42 HYDROIDA II from an almost spherical apophyse situate close under the terminal hydrotheca. The hydrotheca itself is low, somewhat broader at the aperture than at the faint diaphragm, more rarely with margin slightly bent over. Secondary hydrothecse occur in smaller numbers. The hydrotheca stalks are as a rule fairly long, as a rule with a couple of rings below. The gonothecse proceed from the hydrotheca stalks close under the polyp, and are attached by a short, often almost quite rudimentary stalk, or are exceptionally formed as heterorenovates in the hydrothecae. The males are elongated oval or narrowly egg-shaped, attached to the colony by their narrower end. The female gonotheeae are practically pear-shaped, laterally compressed, and with a pair of hydranths in the distal, asymmetrically placed opening; on the side opposite this aperture, the 2 00 m.

A detailed description of Halecium curvicaulr has been given by Dons (1912 p. 61) who shows, that Halecium mirabile Schydlowsky and Halecium repens J ad er holm are synonyms to this species.
