Polypidom adhering’ by creeping' tubulous fibres, erect, irregularly 
branched, the stem and branches composed of many closely applied 
parallel tubes ; branches erect or erecto-patent, cylindrical, straight, 
hirsute from the capillary pedicles of the cells which originate in 
whorls at stated intervals : the pedicles are ringed at top and bottom 
but generally smooth about the middle, patent, simple : the cell itself 
campanulate, thin and transparent with a serrated brim. Vesicles 
scattered, arising from the branches, solitary, very shortly stalked, 
oval, smooth, with a narrow aperture.

There are two varieties of this species : the first is from 2 to 4 inches 
in height, bushy, irregularly branched, the branches straight, square, 
slightly tapered upwards, and formed of several parallel tubes ; (Fig. 4.) 
the second is a single thread-like tube which climbs up the stalks 
of other flexible corallines, giving off on all sides its long spreading 
trumpet-shaped cells, which are not unlike those of C. syringa, but are 
to be distinguished by their thicker and much more horny texture, and 
by being almost or altogether sessile (Fig. 2, 3.) Small specimens 
of the first variety are very common on some sorts of crabs, but the 
larger specimens have their roots or base almost invariably immersed 
in the substance of a sponge, the Halichondria panicea or papillaris. 
Neither the vesicles nor polypes have been observed, and there is 
something in the habit, and in the form of the cells, which renders it 
very doubtful whether this species belongs to this order. 
This appears to be the proper place to notice two doubtful zoo- 
phytes which have been referred to the genus
