The rocks fringing the harbour at Port St. Mary do not 
offer a luxuriant flora. Mud from the inner harbour 
disturbed by the tide appears to exercise a harmful 
influence. Nevertheless, a visit to the Zostera bed (Map II, 
16) in search of epiphytes should be made. The beds can 
be reached via a flight of steps leading on to the shore from 
about the middle of the High Street. 
FLESHWICK Bay. 
This part of the coast does not offer any type of algal 
vegetation that cannot be studied equally well in other 
areas, though the freshwater stream entering the bay 
frequently yields Batrachospermum, and patches of Fucus 
ceranoides on the shore owe their existence to the same 
stream. Amongst the Rhodophyceae to be found here may 
be mentioned Catenella repens which is very common in the 
crevices of the boulders. Until a few years ago this bay 
marked the extreme southern limit of distribution for 
Odonthalia dentata which is still to be found in some 
quantity in the low lying pools, but of late the plant has 
spread with some rapidity and is now to be found occasion- 
ally in all the bays of the survey area. 
Fleshwick Bay is an excellent area for examination of 
cast-up material a day or two after a heavy storm, 
especially if the wind is from the north or west. The set of 
the currents round the coast is such as to bring the detached 
weeds in masses into Fleshwick Bay. Many of the 
inaccessible algae from the sub-littoral zone are thus made 
available to the collector. If an opportunity of dredging 
for algae presents itself, the algologist will be best repaid 
by turning his attention to the mouth of Fleshwick Bay. 
POOYLLVAAISH. 
The rocky promontory at the northern end of Bay ny 
Carricky is an extremely good collecting ground for 
algologists. A rough cart track (Map II, 15), starting
