(e) Laminaria digitata, L. Saccharina, and Chondrus crispus 
in tidal pools. 
(f) Ceramium rubrum (pale brown), and Exteromorpha com- 
pressa (colourless), in, and due to high stagnant pools. 
B. (1) Fucacez association; /: vesiculosus and F. serratus

(2) Plant societies of— 
(a) Ascophyllum nodosum. 
(6) Callithamnion scopulorum and Gigartina mamillosa.— 
Abundant as a lower storey on sea-wall between H.W.M. 
and half-tide mark. 
(c) Chylocladia articulata and Gigartina mamtllosa.—Abun- 
dant as lower storey on sea-wall between half-tide mark 
and L.W.M. 
(d) F- spiralis.—Near H.W.M.; scarce. 
Indubitably supporters of the view that this terminology, as applied 
to marine Alge, is capable of improvement, will not be lacking. 
The writer, however, ventures (with all due modesty) to suggest 
that the value of the suggestion lies in the fact that, if acted upon, 
the study of Algz from the present standpoint will be brought into 
unity and conformity with existing methods of phytogeographical 
terminology.

Short Notes. 
[Zt ts hoped that all will combine to make this section as complete as possible 
by the prompt recording of all ‘‘ new records,” etc. | 
Barbula gracilis Schwaeg. New to Scotland.—In October last 
year I gathered in Glen Phee, Clova, Barbula gracilis Schwaeg. 
This moss, although unrecorded for Scotland, is probably often over- 
looked owing to its resemblance to Barbula fallax. It is rather 
interesting to note that it grows on the same rock faces of quartzose 
gneiss as Oxytropis campestris and S@lania cesia. The moss, as 
is always the case in Britain, was sterile. Specimens were sent to 
Mr. D. A. Jones, Harlech. MARGARET CORSTORPHINE. 
Centunculus minimus, L., 1n Wigtownshire.—In August last I 
found this plant growing in small quantity on Craigoch Moor on the 
footpath on the top of the cliffs approaching Morroch Bay from 
Portpatrick ; a new record for vice-county 74. JAMES FRASER.
