Mr. Turner's Remarks upon 
19- C. Uttorcdis. Litin. — Specimens much better expanded and 
of a paler colour than No. 13. 
20. C. aeruginosa. Linn. 
21. Dr. Roth, in the first volume of his Catakcta Botanica, re- 
ferred this plant, with a mark of doubt, to his C. Hermann^ but in 
the second corrected this reference, and carried it to his C. cirrosa, 
with which, according to specimens sent by my friend Professor 
Mertens, it agrees. It has no connexion with Mr. Dillwyn's 
C. repeats, t. 18. but is hardly distinct from young plants of Hud- 
son's C. pennata. The specimens in the Herbarium differ ex- 
tremely from the magnified figures in the Historia Muscornm, 
their ramification being entirely pinnated, and the branches 
simple. 
22. Sertularia spinosa. C. canccllata of Linneeus, Hudson, and 
other authors. 
23. C. scoparia. 
24. This looks only like a stain upon the paper, if, indeed, it 
really exists there, which we could not determine : it does not 
seem to be noticed by any writer. 
25. There are three specimens of this; one, C. capillaris, Linn., 
the other, what has been called the fresh water variety of it. Dr. 
Roth has named the latter C. capillaris, and the former C. Imum. 
26. A species quite new to us. 
27. C. prolifera. Roth. ? — 1 subjoin a mark of doubt, not from 
any hesitation in my own mind, but because I had not a speci- 
men at Oxford to compare ; and all quotations from memory are 
necessarily liable to error. 
28. This appeared to Mr. Woods and me a new species, di- 
stinct from C. rupestris, to which Hudson has referred it as a 
variety. 
29- C. rupestris. Linn. 
30. Ceramium
