lucernarida

Century Dictionary and Cyclopedia

1. A subclass of Hydrozoa, in which the base of the hydrosome is developed into an umbrella in the walls of which are the reproductive organs. It is a prime division of hydrozoans, equivalent to Discophora in a common acceptation of that term, and has been divided like the latter into three orders: Rhizostomea or Rhizostomidæ, free and with multiple polypites; Monostomea or Pelagiidæ, free and with single polypite; and Lucernariadæ, free or fixed and with single polypite. The last consists of one family, coextensive with the order, and is also called Calycozoa. See Discophora.
