colour or pale green. It grows in tufts on rocks, or stems 
cffnci, in deep water ; it is dichototnously branched, and the 
branches are filiform and spreading. The joints are long, 
lender, and cylindrical, of equal thickness throughout, or but 
slightly enlarged at the upper extremity. The two following 
'Pecies are considered to bo varieties of this, by Fleming, 
■Camouroux and Johnston. 
COCK’S-COMB CORALLINE. Jania Rvberts, (var. b.) 
Dichotomously branched, the upper part of the last joint 
bnt one very much enlarged ; the upper part of the lower 
Joint less so.

The chief differences between this and the last are, that 
he internodes are shorter and stouter, being about two and 
a half times as long as they are thick ; the superior extre- 
mities of the joints are more enlarged, especially the last 
l°'nt but one ; and from the joints being shorter, and two 
. finches arising from every joint, it is also stouter, and more 
‘Pshy than the last. 
It is also liable to great variations of colour, but is gene- 
a| ty either red or green; but when washed ashore it is 
generally bleached. 
S EED-BEARING CORALLINE. Jania Rubens, (var.c.) 
Dichotomously branched; the joints swollen, but the ter- 
minal ones most so.
