aggregated granules or zoospores, contained in the joints, having, at 
some period, a proper ciliary motion. CrapopHora (Av¢z.)—from 
kdddos, & branch, and popéo, to bear. 
Crapornora Rudolphiana ; filaments very long, exceedingly slender, flex- 
uous, subgelatinoso-membranaceous, much branched, brilliant, yellow- 
green, inextricable ; branches, di-trichotomous, or irregular ; ultimate 
ramuli pectinate, secund, very Jong and much attenuated ; articula- 
tions of the main filaments many times longer than broad, here and 
there swollen, their granular endochrome somewhat spiral; those of 
the ramuli 6-10 times as long as broad.

Descr. Filaments exceedingly slender, forming very flaccid, subgelatinous 
tufts from six to twenty inches in length, excessively branched, and in most 
cases inextricably entangled. The branching appears to be an irregular 
combination of dichotomous, and alternate, with here and there some oppo- 
site branches; and all the main divisions are either very flexuous or angu- 
larly bent. The ultimate ramuli are very long, attenuated to a fine point, 
and disposed in secund, subpectinate groups. Frequently one of the joints 
swells into an elliptical or spindle form, but without much apparent altera- 
tion in its nature. All the joints are of great length, as compared with 
their diameter, those of the main filaments being upwards of ten times 
longer than broad; those of the ramuli from six to ten times. Their endo- 
chrome is lax, pellucid, and its granules are attached in subspiral lines to 
the walls of the cells. The colour is a rich glossy green; the substance 
very soft; and the whole plant adheres closely to paper in drying, and pre- 
serves its colour. 
PARARA RRA 
One of the commonest sea plants in Roundstone Bay, Cunne- 
mara, where it infects every object on which it can lay hold, at a 
depth of from two to six fathoms, or perhaps more. It is very 
frequently found on the Laminaria, on Zostera, &c. Whilst 
young, and freely waving in the water, it is a very beautiful
