Tubularia (Gmelin). 
Moschata (Blainville). 
Edwardsia (Forbes). 
Column lengthened, cylindrical, swollen and bulb- 
like at the inferior extremity, which is perforated with 
a distinct orifice ; expanding trumpet - like at the 
margin, which merges into the tentacles,, without 
parapet or fosse. Surface smooth, without loop-holes, 
or (apparent) suckers. Usually enveloped in a loose, 
non-adherent tube, closed at the lower end, of tough, 
membranous texture, and ragged exterior. 
Dish wider than column, but not over-arching : 
funnel-shaped, with conspicuous radii. 
Tentacles of two kinds j the one marginal, the other 
gular ; both in perfect circles, those of each equal 
inter se, moderately numerous, slender ; absolutely 
incapable of retraction. 
There is but one British species as yet certainly 
assigned to this genus, C. Lloydii.
