\Tu`bu*la"ri*an\, n. (Zool.)
Any hydroid belonging to the suborder Tubularida.
Note: These hydroids usually form tufts of delicate tubes,
      and both gonophores and hydranths are naked. The
      gonophores of many of the species become free
      jellyfishes; those of other species remain permanently
      attached as medusoid buds or sporosacs. See Illust.
      under {Gonosome}, and {Cymnoblastea}.
