Century Dictionary and Cyclopedia
    • n calycozoa An order of discophorous hydrozoans, the lucernarian acalephs: so called because of their cup-shape, having the umbrella or disk without a velum, pedunculated aborally, and capable of attachment at the aboral pole. They have four wide vascular pouches with narrow septa, and eight tentaculiferous processes around the edge of the umbrella, dividing it into as many lobes, the generative products being discharged into the body-cavity. There is but one family, Lucernariidœ. These organisms are of gelatinous consistency, variously colored, and semi-transparent; when detached, they swim, like all medusoids, by contractions of the umbrella. They are regarded by some as the most generalized type of the class. Leuckart. See Lucernaria.
