attention being given to groups which are at present poorly repre- 
sented. Material in formalin, of parasitic and endophytic algae, 
and of other species which cannot properly be re 4 in a dried 
state, was also obtained. 
e first visit, necessarily more or less of a preliminary character, 
may be regarded as entirely satisfactory, both as to the suitability of 
the site for algal exploration and as to the amount of work that was 
accomplished, 
Various types of collecting ground are met with. On Clare Island 
itself the rocky exposed shores offer a typically “ exposed ” flora. 
On the mainland such channelsas Achill Sound afford quiet but fully 
saline conditions, where a “sheltered” type of flora exists, the 
growth here being often exceedingly luxuriant, Clew Bay, with 
its innumerable islands and sand banks, presents another and different 
type of vegetation, which may be termed a sand-bay flora, where 
every transition from exposed to sheltered conditions may be found, 
Land-locked bays, such as Bellacragher, furnish brackish water, 
where a fourth and characteristic vegetation obtains. Mudd 
ground with mud-loving species is also supplied in many parts of 
Clew Bay. To obtain a detailed knowledge of the algae of such a 
district, each of these types of collecting ground shou 
examined thoroughly, and that as often as possible throughout the 
year. Many of the smaller algae are very transient in their appear- 
ance, so that unless frequent collections be made, their presence is 
liable to be overlooked, It is thus manifest that, though an 
endeavour will be made to visit the Clare Island district as often 
as possible, any collections and observations by other botanists 
would be of great assistance. Eoin oA ae
