upper part of the frond shows 4-8 cells radially arranged. Each 
individual filament is attached singly to the Zostera leaf by its 
slightly expanded basal cell. In many respects the plant resembles 
a Bangia, but the spores are formed exactly as in the other species 
of Hrythrotrichia. As has been shown above, Berthold is wrong in 
referring the plant to Bangia ciliaris Carm. (for which the name 
Hrythrotrichia ciliaris must be retained). I have been compelled in 
consequence to give it a new name, and have called it after the 
botanist who first clearly described it.

Fronds pale purple, 10-20 mm. long, very slender below and formed 
of a single cell-row 10-15 » broad, which by longitudinal and 
transverse division of the cells gradually expands into a very thin, 
at, monostromatic frond 200-800 » broad; margins crenate, more 
or less crisped and curled. On Zostera, in company with E. Ber-

I found this very pretty variety of E. Boryana growing in 
company with the preceding, on Zostera leaves sent from the 
Scilly Isles by Mr. George. e fronds are very much longer and 
broader than those of any other British specimens of the species 
that I have seen; and the margins, instead of bein quite entire 
(‘‘ margini integerrima”’), are notched and crisped, sometimes so 
much so that the frond appears spirally twisted.

plant is really a form of Schmitz’s Erythropeltis discigera ; but 
cannot think it the same as Erythrotrichia discigera Berthold 
although the fronds in many respects resemble the discs of that 
species when no erect fronds are produced.
