On October 2 a strong Cryptoganiie party crossed to the island, com- 

 prising Sir H. G. Hawley (Fungi), A. D. Cotton 'Marine Algae), Miss A. 

 Lorrain Smith (Lichens and Fungi), Miss Beatrice Taylor (Lichens), and 

 Miss Knowles (Lichens) ; the party also included Miss Stephens (Sponges) 

 and R. LI. Praeger. Four to six days'' collecting was done on the island by 

 the various members, after which they scattered; and the Achill Sound, 

 Louisburgh, Eelcla-re, Westport, and Castlebar districts all received 

 attention. 



A late fungus foray was carried out during the third week in November 

 by Carleton Sea, accompanied for two days by R. LI. Praeger. Operations 

 were hampered at the beginning by snow lying on the ground, but this soon 

 passed away, and a good list of the later kinds was made, including no less 

 than thirty species new to the Irish flora. 



The last visit of the season was made by Prof. Patten, who crossed to the 

 island on December 27 to spend a week in studying the winter avifauna.

The third season's field-work began early. A. D. Cotton went west on 

 February 13 to study the winter Alga flora at Louisburgh and Achill Sound. 

 He was followed on March 7 by Gr. H. Wailes and the late James Murray. 

 The latter spent a week in collecting Bdelloid Rotifera and Arctiscoida in 

 Achill, Clare Island, and the Louisburgh district. Mr. Wailes took up his 

 residence on Clare Island, and remained there till June 3 working at the 

 Rhizopoda, and collecting not only on Clare Island, but in Achill, at Roonah, 

 and on Caher Island, Inishturk, and Tnishbofin, the result being one of the 

 most complete lists of Rhizopods ever formed for a single district. He was 

 joined for a few days in March by R. M. Barrington, who studied the Birds 

 of the island. 



On April 13 J. S. Dunkerly and G. 0. Sherrard went down for a week 

 and, using Belclare as headquarters, collected Infusoria and Nematodes 

 respectively. 



The first combined party of the season left Dublin for the island on 

 April 27. It included Sir H. C. Hawley (Fungi), A. D. Cotton and Dr. F. 

 Borgesen of Copenhagen (Marine Algaej, F. J. Lewis (Peat deposits), R. LI. 

 Praeger, and several others. While most of the party returned at the end 

 of a week, A. D. Cotton worked on at Louisburgh and Achill till May 15. 



On May 29 Rev. W. F. Johnson and Mrs. Johnson went down, and spent 

 a month, mainly on the island, collecting insects. In connexion with the
