1914, and was rewarded by being able to certify its oj mee in 
Courtmacsherry Bay. It occurred on its usual host Laminaria 
ep 
ashore at several places in the bay after a gale. Miss Duke also 
discovered another northern alga, Callithamnion arbuscula, which 
was fairly abundant on perpendicular rocks near the Old Head of 
Naturalist for March, 1915 (xxiv. p. 55), entitled ‘‘Some Marine 
Alge of County Cork.” With regard, aga gs to the ee 
element, as seen in the algee of the west of Ireland, we may 
reasonably conclude gan a oxen not only to the counties 
of Clare deg Kerry, but a 
osum up, the distribution of Prilota plumosa still poeseee the 
same apr t. It is a markedly northern alga, but is found along 
the west of Ireland and round the south-west corner rs near Cork 
arbour. On the west coast of Great Britain there is no record 
of its presence as an attached plant south of Anglesea, though two 
odd fronds collected near Ilfracombe merit notice hee Journ. Bot. 
, footnote, and Miss Larter’s plant, noted above). 
Where Ptilota occurs at all itis usually plentifal, a as explained 
by Mr. Holmes s(n cit. p. 206), the presence in a well-known and 
well-worked locality of a single odd specimen washed ashore is 
always to be viewed with suspicion. The boreal element in the 
algee which oe present in the flora « ) dale we south- 
suitable a in Irelan d, Wales and England, is ia still one of the 
many puzzles provided by Irish botany.
