new. ` One of them is a Laminaria, its frond is simple and 
like a ribband, frequently a fathom in length, nerveless, with 
a spathulate base, of which the auricles are turned and 
twisted inwards, on which account I have given to this 
species the name of F. Cornucopie. The stipites, of which 
two spring from each root, ascend in opposite directions, 
and strike down a few fibres from their under-side; soon 
after, each stipes expands into the spathule that I have 
described. This Laminaria, which comes nearest to L. 
saccharina, can neither be confounded with it, nor with any 
other: it always grows singly; though the roots of six or 
eight individuals are often so interwoven, that they cannot 
be easily separated. Perhaps the F. bifidus, Gmelin, is but 
an imperfect and ill-described specimen of this plant. 
* A second, hitherto undescribed and no less rare species 
on the coast of Kamtschatka, is completely spongy, and 
might, at first view, be taken for a Spongia; but a slight 
examination of its internal structure removes all doubt of 
its vegetable or fucoid nature. It may rank near F. tomen- 
tosus, and consequently belongs to the genus Codium of 
Agardh: I have provisionally called it F. dam«ecornis ; the 
sessile and variously divided frond, cut in many irregular 
segments to the very base, each segment being again digi- 
tate and lobed, gives it a resemblance to the anthers of a 
fallow-deer. "This sea-weed is chiefly found growing on the 
stems of F. Clathrus ; its colour is a brownish purple, and 
its touch and appearance resemble Manchester velvet. The 
circle which a single frond describes often exceeds a foot; 
its thickness is about a line; and when cut through, there 
appear many yellow granules, filled with a fluid, imbedded 
among fibres. This species dries very readily, contrary to 
expectation, and in doing so, exhales no unpleasant odour. 
“ The third new species which I shall enumerate, is here 
found very plentifully, though good specimens are rare; 
Turner mentions it in his Historia Fucorum, though both 
his figure and description leave many points in doubt, as 
the Kamtschatkan form of F. saccatus. Agardh quotes this 
form as the original and true appearance of F. saccatus,
