bushy, dicliotomously divided, the branches inclining- inwards ; the 
joints jet-black ; the internodes narrow at their origin, widened up- 
wards ; the cells entirely adnate, tubulous, semi-alternate, with round 
even apertures. This, thoug-h in many respects similar to the pre- 
ceding-, is yet essentially different, and has been well characterized by 
Dr Fleming-. It is of a denser texture ; the branches, or rather the 
spaces between the joints, are longer, broader and thicker in the mid- 
dle ; the cells are more closely connected ; their orifices are not de- 
tached from the sides, and the joints are black, so that the polypidom 
appears dotted to the naked eye.

“ Height scarcely an inch, dichotomously branched ; the cells en- 
large gradually in breadth towards the top, which is armed with two 
or three spines ; when the outermost one is short, the cell external- 
ly has an angulated appearance ; at the joints the stem is narrow.”

Character. Polypidom plant-like , sub calcareous, rather soft 
and flexible when dry , much branched, dichotomously : cells gemi-

ment, a joint above and below each pair. — Polypes ascidian.
