1922. ScHARFF. — Thirty Years'' Work of the Irish Naturalist. 5 



many common birds contributed by C. B. Moffat and J. P. 

 Burkitt, and the observations on migrants at lighthouses 

 by Prof. C. J. Patten. Articles of much interest were 

 contributed also by the late Rev. Dr. C. W. Benson, and 

 G. E. H. Barrett-Hamilton, by D. C. Campbell, W. E. 

 Praeger, R. F. Ruttledge, and many others. Early in the 

 career of the Irish Naturalist the present writer discussed 

 the " native " standing of the Common Fiog in Ireland, 

 and was opposed in his opinion by W. F. de V. Kane. 

 E. W. L. Flolt wrote on new Irish Fishes, and C. T. Regan 

 on Irish Char. 



Turning to invertebrate animals, my list of Irish Land 

 and Freshwater MoUusca published in the first volume has 

 been followed up by a series of valuable papers on particular 

 species or the fauna of special districts by Rev. E. W. 

 Bowell, Prof. A. E. Boycott, R. A. PhilUps, A. W. Stelfox 

 and R. Welch. Important anatomical and s^^stematic 

 work on Vitrina, Limnaea, Pisidium and other genera is 

 included. Marine Mollusca have been dealt with in papers 

 by N. Colgan, G. W. Chaster, A. R. Nichols and other 

 conchologists. Our knowledge of Irish Insects has been 

 materially advanced by the work of F. Balfour Browne, 

 G. H. Carpenter, J. N. Halbert, Rev. W. F. Johnson, the 

 late W. F. de V. Kane, D. R. Pack-Beresford, and others 

 embodied in an extensive series of systematic and bionomic 

 articles and local lists. Besides the more familiar Lepidop- 

 tera and Coleoptera, Hemiptera, Hymenoptera, Diptera 

 and the lowl}/ Apterygota are dealt with in these papers. 

 Irish Arachnida have been dealt mth by G. H. Carpenter, 

 D. W. Freeman, J. N. Halbert and D. R. Pack-Beresford, 

 and Crustacea by R. H. Creighton, W. F. de V. Kane and 

 others. The terrestrial Crustacea (Oniscoidea) have been 

 listed and described bv the writer of this article and N. 

 H. Foster, while Rev. FI. Friend, R. Southern and others 

 have dealt with various groups of worms. R. Hanitsch's 

 paper on Irish Freshwater Sponges is noteworthy as the 

 earliest pronouncement on the definitely American element 

 in the Irish fauna, though his supposed three transatlantic 

 species have been reduced to one by the subsequent work 

 of Mrs. Scharff.
