Clare Island Survey — Musci and Hepaticae. 11-12 5 



abode for Bryophytes, has, strange to say, very few of them. Eound this 

 lough the ground is much shaded by the cliffs from the direct rays of the sun, 

 the air is moist, and there is shelter from stormy winds ; these are data which 

 generally determine where Mosses and Hepatics will establish themselves 

 and flourish, but they avoid this spot. 



In the centre of the Curraun peninsula lies the beautifully situated Lough 

 Knockacurraun at an elevation of 600 feet above sea-level ; on all sides but 

 one it is surrounded by hills that reach 1000 feet higher. And here along the 

 west and south margins of the lough the stones and rooks are covered with a 

 profusion of Mosses and Hepatics, several of which are rare. These grow at 

 the edge of the water, which in summer and winter alike is always at the same 

 level, and they are except for a few hours about midday out of sunshine, and 

 at the same time are perfectly sheltered from any wind. 



One of these plants, Eadula lindberyii, which is a new record for Ireland, 

 was also found on the island at Toormore in a spot very different from its 

 peaceful habitat here in Curraun. 



2. FIELD-WORK. 



Previous to this survey no bryologist is known to have visited Clare Island, 

 while the only portion of the mainland included in the area which had been 

 worked for Mosses and Hepatics was Aehill Island, which, from 1901 to 1908, 

 had been examined with fairly satisfactory results. The visits, the results of 

 which are herein scheduled, were —
