40 MR. G. 8. BRADY ON MR. WINCH’S ALGAE. 
Il.—Remarks on some of the Algae in Mr. Winch’s Herbarium. 
By Groner 8. Brapy. 
In the Catalogue of the Marine Algex of Northumberland and 
Durham, published in the fourth volume of our Transactions, I 
had to quote several plants as natives of our district on the 
authority of Winch’s Flora, which refers in several instances to 
specimens preserved in his herbarium. I was therefore anxious, 
for the sake of verifying these references which seemed to me in 
many cases more than doubtful, to have an opportunity of ex- 
amining the original specimens now in the possession of the 
Linnean Society. I am indebted to the President and Council 
of that Society for permission to examine the collection, 
which, through the intervention of my valued friend Professor 
Oliver, was kindly sent down to me for this purpose. The result 
of my investigation is contained in the following notes :— 
ELAcHIsTa FLACCIDA, Catalogue p. 279. The specimen found 
near Berwick, and named by Dr. Johnston, is clearly referable 
to the common species, #. fucicola. E. flaccida must therefore 
be expunged from our list. 
Exacuista curta, Dillw. A specimen so named is very dis- 
tinct in appearance from any species known to me, and agrees 
very well with Dr. Harvey’s description, but Dillwyn’s plant 
seems to be quite unknown to recent collectors and to Dr. 
Harvey, except from a single specimen preserved in Sir W. 
J. Hooker’s herbarium. Winch’s specimen was found on the 
stem of a Fucus at Seaton, and is very probably rightly re- 
ferred to E. curta. 
MESOGLOIA VERMICULARIS, Cat. p. 278. MM. virescens is er- 
roneously called vermicularis in Winch’s collection. For the 
latter species, therefore, the Holy Island habitat is the only 
one at present known in our district. 
PoLysIPHONIA sTRICTA is referable to P. urceolata. 
CALLIBLEPHARIS CILIATA, Cat. p. 295. The two specimens of 
this species are rightly named, and are the only ones which I 
have seen from our coast. |
