1. Notes on Irish Freshwater Mites. 



By J.N. Haibert.

eingeg. 19. December 1902. 



Most of the Irish Freshwater Mites agree in their characteristics 

 with common and widely distributed species. Yet interesting forms 

 occur which are little known, while a few are new to science. 



The following notes chiefly refer to certain of these uncommon 

 species so far as they are contained in the genera Hydraclma and 

 Arrhenurus based on collections made in various Irish localities during 

 the last four vears. At the same time lists of the species of these 

 genera which have hitherto been found in Ireland are given, in the 

 hope that they may be of use to those interested in the distribution of 

 these freshwater organisms. 



1) Hydraclma incisa n. sp. 



During life of a purplish red colour with ill-defined darker mark- 

 ings; legs red, pale yellow at the insertions of the segments. Length 

 3,5 mm, breadth 2,7 mm. In shape the body is distinctly truncate in
