MR. WINCH’S HERBARIUM. Al 
Crramium ciuiatum, Cat. p. 803. The species so named is C. 
acanthonotum. C. ciliatum bas not yet been found in this 
district. 
GRIFFITHSIA EQUISETIFOLIA, Cat. p. 304. A single specimen of 
. this plant, found washed up-at Hartlepool, is the sole warrant 
for its insertion in the Catalogue. There can be no doubt of 
the correctness of the reference. 
GRIFFITHSIA CORALLINA, Cat. p. 804, must be excluded from our 
list. The specimens so named by Mr. Winch are really G. 
setacea. 
CALLITHAMNION TETRAGONUM, Cat. p. 306. Thespecimens given 
under this name must be referred to C. Arbuscula. 
CLADOPHORA GRACILIS, Cat. p. 309. A specimen of this plant 
from tide-pools at Seaton is called by Mr. Winch C. letevirens. 
It is the only example of C. gracilis that I have seen from the 
Durham Coast. 
Of the following species, which were included in the Catalogue 
on the faith of Mr. Winch’s “ Flora,” I have found no trace in 
his herbarium, and I fear we must consider their claim to con- 
sideration as denizens of our district to be null and void until 
more fully confirmed :—Cystoseira ericoides, Arthrocladia villosa’ 
flalseris polypodioides,* Sphacelaria scoparia, Polysiphonia fibrata 
Codium tomentosum, Rivularia atra, Calothoriz scopulorum. 
* The collection contains a specimen of this plant, but no locality is given. I have never 
found the species on our coast, though Mr. Winch says it is ‘not rare,” and as it is one 
which could not well be overlooked, it is most probable that Mr. Winch confounded it with 
some other species. It must be remembered that when the “ Flora” was published, the 
Alge and all the lower forms of iife were but very imperfectly understood, and the micro- 
scope was just beginning to be known as an instrument of research. We cannot but expect 
that a list composed under these circumstances would show many and serious inaccuracies.
