On Ulva Lactuca, Appin, rare. Captain Carmichael. ©. Autumn.
It occurs in stellated tufts, 2—3 lines in diameter. Filaments about 2
lines in length, straight, equal or a little broader at the point. Granules in
double, approximated fasciae, and generally 4- in each. Cann.
4. B. ? ketevirens, Harv. (bright-green Bangia) ; filaments
minute tufted flexuose attenuated to a subobtuse point brightgreen,
fasciae close composed of innumerable minute granules.

On old fronds of Enteromorpha intestina/is, which grow on precipitous
rocks at the extreme verge of high-water mark, Pavington, Miltown
Malbay, Ireland, Mr. Harvey. 0. Summer.— " Filaments simple, minute,
two or three lines in height, fascicled, many in the same tuft, lubricous,
bright yellow-green, tapering to a subacute point, flaccid and
slightly curved. Fascice rather broad, close, evidently containing granules,
but so minute and numerous that it is impossible accurately to examine
them. It is conspicuous|on the old dull-coloured fronds of Enteromorpha,
by its bright green colour. The genus of the present plant is far from cer-
tain in my mind, but I think it more nearly related to Bangia than to
any other." Harvey.
5. B. kzeustris, Cann. (lacustrine Bangia); filaments scattered
decumbent branched deep green, the branches divaricated
acute, fascia? of ternate globose granules. Cann. MSS. cum 1c.
On the submerged leaves of aquatic plants, Appin, Captain Carmichael.
©. Summer.— " Filaments not exceeding a line in length, of a deep
green colour, scattered, tortuous, creeping, and apparently fixed at or
near the centre, attenuated at both ends and divaricatedly branched ;
sporidia globular, arranged in transverse series of 3 in the same filament,
and 2 in the branches." ('arm.
