fine forming a cloudy floating yellow-green stratum, articulations
3—5 times longer than broad. Ag. Syst. Alg. p. 88. C.

In stagnant waters, about the stems of aquatic plants, common.

5. C. floccosa, Ag. (floccose Conferva); filaments very
slender forming pale-green floating strata, articulations once or
twice as long as broad. Ag. Syst. Alg. p. 89.— C. fugaeissima,
Dillw. Conf. Suppl. t. B.
In ditches and pools; very nearly allied to C. bombycina, but " much
more robust, fine as it is ; besides the great disparity of the articulations.'*
Grev. I have frequently found the two growing together.
6. C. zondta, "Webr. et Mohr, Ag. (banded Conferva); filaments
unequal forming bright-green lubricous masses, articulations
rather longer than broad marked in the centre with a
full-green band. Ag. Syst. Alg. p. 90. Dillw. Conf. Syn.p. 41,
and C. lubrica, t. 47.
On stones, in rivulets.
7. C. vesicdta, Ag. (inflated Conferva); filaments very
slender forming dull-green strata, articulations variable in
length 2—5 times longer than broad, here and there inflated.
C. vesicata, tumidula, Candollii and Borisii, Ag. Syst. Alg.
pp, 93—94.— C. alternata, Dillw. Conf. Syn. t. B.—C tumidula,
E. Bot. t. 1670.
In stagnant water, common.—In uniting the above four species of
Agardh, I gladly follow Capt. Carmichael, who remarks, that " in a
genus so notoriously variable in the length of the articulations, the
differences indicated in the definitions will hardly entitle them to rank
even as varieties."
8. C. rividdris, Linn. (River Conferva); filaments slender
very long straight
articulations 2—4
bright-green silky forming tufted bundles,
times longer than broad. Ag. Syst. Alg.
p. 95. B. Bot. t. 1654. Dillw. Conf. t. 39.
In streams and rivers, common.—2—3 feet long, tutted. I have
never seen the joints so short as represented by Dillw vn ; but his
figure is, En other respects, characteristic.
9. C. mucosa, Mert (mucous Conferva); filaments formings
floating bright-green stratum extremely gelatinous invested
with definite mucus, articulations about as Long as broad
DiUw. Conf. Syn. i. />'. (bad.) Ag. Syst. Alg. p. 90.
In stagnant water, rare. Bantry, Mi i Hutch is. Appin, Capt. Car*

cal, by no means fragile, surrounded bj mucous envelope, twice their
own diameter. Articulations about as broad ss long* Svorular mass Bome*
times filling the whole joint, sometimes about two-thuds. In the latter
.-. the contrast between the opaque and transparent parts of the Joint,
-. the filament a remarkably beautiful appearance. In drying, it discharges
a profusion of large granules, and becomes slightly contracted
