. Bulletin of the United States Fish Commission. Fisheries -- United States; Fish-culture -- United States. HYDROIDS OF BEAUFORT, NORTH CAROLINA. 371 lished, since the gonophores do not produce free medusae. To that genus I have given the name Scandia. The specific name "mutabilis" has priority and has therefore been retained. Prof. Nutting has kindly given me permission to use the family name, Hebellidse, in this paper. It thus appears containing the two genera Hebella and Scandia. Key to the Genera of the Found in the Beaufort Region. A. Gonophores producing free medusae

Gonophores producing sporosacs Scandia. Genus HEBELLA. Trophosome.—Colonies consisting of single hydrantlis attached by short pedicels to a stolon, which usually creeps over other hydroids. A distinct diaphragm is present in the hydrotheca. Gonosome.—Gonophores producing free medusae. Hebella calcarata (A. Agassiz). Laf(xa calcarala A. Agassiz. North American Acalephae, 1865. p. 122.

Hebella calcarala Nutting, Hydroids of the Woods Hole Region, 1901, p. isi- Trophosome.—Colony commonly creeping on other hydroids, especially sertularians, in which case the stolon may creep along the axis of the sertularian and give off its hydrothecae more or less regularly.
