Their observations seem to be limited to certain groups, 

 such as Ccelenterates, Polychsets, Molluscs, and Tunicates. 



Protozoa.— Mr. G. C. Gough's list of the Foraminifera of 

 Larne Lough and district 1 contains several species new to the 

 district and one new to the Irish fauna. Until a properly 

 authenticated list of Irish Foraminifera has been published, 

 which is still a desideratum, it may be somewhat premature 

 to refer to a species as new to the Irish fauna, for there are a 

 good many records hidden in the Proceedings of the Dublin 

 Microscopical Club and other societies which ought to be col- 

 lected and tabulated so as to form a basis for future workers ; 

 but possibly Mr. Joseph Wright possesses a manuscript list 

 which may have been accessible to Mr. Gough. 



Ccelenterates. — Miss M. J. Delap carried her previous 

 investigations further in keeping some of the large jelly- 

 fishes — viz., Aurelia aurita and Pelagia perla — in an aquarium 2 , 

 observing the progress of their early development from the 

 egg through the larval stages. 



Worms.— Mr. Holt records 3 the occurrence of a peculiar 

 marine leech, Branchellioii torpidi?iis, in Irish waters. He 

 found it attached to the fin of a specimen of the Thornback 

 Ray. 



Crustacea. — This group is specially dealt with by Mr. 

 Kemp, Mr. Pearson, and Mr.jTattersall. Mr. Kemp 4 describes 

 two species of the cray-fish Acanthephyra from the deep 

 waters off the west coast of Ireland, viz., A. purptcrea and 

 A. debilis. This genus, though widely spread, seems to have 

 its headquarters in the Indian Ocean, and its occurrence in 

 Irish waters is therefore of considerable distributional interest.
