172 DR. HARVEY ON A COLLECTION OF ALGE 
gustioribus, apicibus acutis, cystocarpiis in discum v. ad marginem 
laciniarum sessilibus. 
Dredged in 8-10 fathoms, and cast ashore, Esquimalt, Dr. Lyall. 
The smaller specimens so exactly resemble Euthora cristata, 
that it is difficult to persuade oneself, without dissection of frond 
and fruit, that they belong to a different genus. The larger look 
like small varieties of Callophyllis variegata, and yet are not iden- 
tical; some very narrow ones are equally like the narrow and 
dwarf states of C. coccinea. The colour is a bright red. The sub- 
stance is somewhat rigid, but very imperfectly adhering to paper. 
The average width of the segments is 1-2 lines.

Open beach, Esquimalt, Dr. Lyall. 
A few small specimens. They are less fastigiate and broader 
than C. flabellulata, with more cuneate and obtuse or truncate seg- 
ments, and of much softer substance.

Adrift on the beach, Victoria Harbour, Dr. Lyall. 
Perhaps this is only a luxuriant state of C. rosa-marina. The 
lamina in our specimens is torn, but must have been 6-8 inches 
in diameter when perfect.

Dredged in Esquimalt Harbour, 10 fathoms, Dr. Lyall. 
A single specimen.

Var. a. vulgaris. Repetite ramosa, laciniis angustis cuneatis linearibusve. 
Var. B. latissima. Parce dichotoma, laciniis latissime cuneatis truncatis. 
Esquimalt Harbour, Dr. Lyall. 
Between the broadest and simplest and the narrower forms 
there seems a direct passage ; nor can I distinguish such varieties, 
more than similar states of Chondrus crispus. I have seen no au- 
thentie specimen of Agardh’s “ G. papillata" (from the Sandwich 
Islands); but his description agrees well with the broader and 
simpler of the Esquimalt specimens.
