Lorrain Smith has undertaken the bacteriological investigation of certain 

 shellfish ; and Professor Milroy has commenced work on the 

 physiological effects of light on the eyes of fishes. 



Besides these workers numerous members and others have visited the 

 Marine Station at Larne Harbour. At Easter, a party of fifteen members 

 worked there for several days, and almost every Saturday one or more 

 visitors join the naturalist in his dredging expedition. Professor Brady, 

 F.R.S., of Newcastle, has been the only zoologist who has come from a 

 distance to work ; but several other prominent naturalists have indicated 

 their intention of visiting the laboratory, and they will, of course, be 

 heartily welcomed. 



Besides marine work the Association has undertaken the study of the 

 fauna of Lough Neagh. This is carried on without a special laboratory. 

 Mr. Pearson makes periodical visits of inspection, collects material and 

 statistics, and ■ with the help of several other workers tabulates the 

 results, which promise to be of importance in connection with fishery 

 problems. 



The naturalist's Report describes the details of the dredging and 

 trawling work. Physical observations, notes of deposits, records of the 

 contents of fish's stomachs are carefull}' made. At Lough Neagh, which 

 is visited for about two daj's a month, special attention is paid to Mysis 

 relida. 



The adoption of the Reports, moved by the Chairman, seconded by 

 the Rev. President Hamii^Ton, and supported by the Lord Mayor of 

 Belfast, was carried unanimously. 



NOTES. 



BOTANY. 



Catenella repens at Ballygally Head. 



Catenella repens^ Lightf. , which belongs to the group of Red Seaweeds 

 and is also known by the name Catenella Opuntia, Grev., was found on 

 23rd September, 1903, on the rocks beneath the old castle at Ballj^gally 

 Head, Co. Antrim. It grew on the shady surfaces of the crevices near 

 highwater mark. The specimens possessed reproductive organs, but 

 whether these were tetraspores or young stages of cystocarps has not 

 yet been fully determined. The only Irish localities for this plant given 

 in Batters's " British Marine Algae " (1902), are Bantry Bay and Dublin 

 Bay. As shown by Harvey-Gibson {/ourn. Limt. Soc, 1892), the figure of 

 the cystocarp, with the accompanying description in Harvey's 

 " Phycologia Britannica," is altogether erroneous.
