The following lists of mosses and liverworts are the result 

 of a week's collecting in July last year. I went from Dublin 

 to Ballinrobe, from there I drove on a car to Clonbur, a 

 distance of about nine miles, and on the route enjoyed the 

 view of Lough Mask and mountains, with numerous islands 

 in the foreground of the lough, making a pretty picture. In 

 Mount Gable Hotel I was soon comfortably settled, and I 

 made excursions, collecting every day. My first trip was to 

 Ballard, on the shore of L,ough Corrib, along which I worked 

 around to Carrick, and then took a boat and rowed over to 

 one of the promising islands called Illaunaknick. As the 

 boat grounded I gathered Cinclidotus fontinaloides, which was 

 plentiful on the stony margin of the little isle, where it is often 

 submerged. Some very fine specimens of the Little Tree- 

 moss (Climacium dendroides) were growing amongst the moist 

 rocks. 



Liverworts were scarce. Frullania germana grew sparingly 

 on the trunks of Alder trees, with a proliferous form of 

 Metzgeria furcata. Mosses w r ere better represented, and I 

 collected twenty species on the little island. A most interesting 

 day was spent in the limestone district of Cong, where I 

 tramped through acres of white flat rocks ; with more or less 

 success. The route from Clonbur was by the splendid demesne 

 of Ashford, with its extensive woods and coverts. I spent a 

 long time in the Pigeon Hole cave, near the village of Cong, 

 which one can descend by rude stone steps on the rocky walls. 

 Mackay's Lejeunea was growing plentifully. I was glad to find 

 this curious liverwort. The only district near this that I know 

 of where it grows is on rocks by the margin of a small lake near 

 L,etterfrack, which is in County Galway. In the cave it was 

 growing in company with Metzgeria furcata, and they grew so 

 tightly to the rocky walls that I had to scrape them off with a 

 knife. On the rocky steps and away down in the dark where
