T h E late excellent Dr. Wenman of All Souls College,
Oxford, was the original finder of this rare Fucus on the Comith
coaft j for the other fpecimens alluded to in the Linnsean
Tranfactions were gathered by Laefling at St. Ubes in Portugal.
We are hpwever enabled to confirm Dr. Wenman’s dif-
covery, by means of one fine fpecimen found by Dr. Mac-
pullock, growing on a bank of Sabella, in Mounts-bay, near
Newlyn, Cornwall. It has been fent to Mr. D. Turner by
Profefior Mertens of Bremen, under the name of F. pijlillatus
pf Gmelin.
Many fronds grow from one callous bafe, and are various in
height from 2 to 5 inches; their fubftance is rigid and homy;
their colour blackith at the bafe, dull-red upwards, paler and
often greenifh at the fummits. Each frond is linear, flattifh,
forked, and varioufly branched, ending in taper points, and
furniffied in the upper part chiefly with fpinous teeth, the
rudiments of branches. The fructification is ftriking and
eharadteriftic, confiftingofdark-red feffile lateral globules, containing
a duller of feeds, which at length come forth at $
ermipal orificp.
