Virgularian \Vir`gu*la"ri*an\, n. [From. L. virgula a small
rod.] (Zool.)
Any one of numerous species of long, slender Alcyonaria
belonging to {Virgularia} and allied genera of the family
{Virgularidae}. These corals are allied to the sea-pens, but
have a long rodlike rhachis inclosing a slender, round or
square, calcareous axis. The polyps are arranged in
transverse rows or clusters along each side of the rhachis.
