4. C. pdrvula, (least Chylocladia') ; frond with scattered entangled
branches, the constrictions nearly equal in length and
breadth, capsules ovate containing a sphserical mass of wedgeshaped
seeds.— Gastridium parvidum, Grev. Alg. Brit. p. 119.

Parasitic on the larger Algae. Coast of Devon, Mrs. Griffiths.
Brighton, Mr. Borrer. 0. Summer.—2— 3 inches long. Distinguished,
according to Dr. Greville, from C. kaliformis, of which it will be seen
that Mr. Turner makes it a variety, by the ovate capsules, destitute of a
pellucid border. Mrs. Griffiths observes that its fructification is produced
a month later.
5. C. articuldta, (articulated Chylocladia); frond tubular constricted
throughout as ifjointed much branched dichotomous and
whorled subfastigiate, articulations subcylindrical, capsules urceolate.—

Summer.—Three and four inches to a foot in length, in some of Miss
Hutchins' specimens from Bantry; and varying much in the thickness of
the frond ; the whole jointed in a catenulated manner. " There is not
much," observes Captain Carmichael, " in the definition to distinguish
this species from C. kaliformis, though, to look at them beside each other
we should pronounce them at once to be distinct. Lyngbye has fallen
upon an ingenious contrivance to avoid the confusion that might take
place from too near an approximation of them. He has erected the latter
into a separate Genus; nor only that, he has transferred it into a different
section under the idea of the frond being solid, which assuredly
it is not, at least in this part of the world." Carrn.
34. Gigarti'na. Lamour. Gigartina (Gigartina and Gracilaria.
Grev.).
Frond more or less cartilaginous, filiform, cylindrical or
compressed, irregularly branched, of a dull red colour. Fruc-
tification ;—capsules containing a mass of minute roundish seeds;
and (in many of the species, perhaps in all) roundish or oblong,
