104 Proceedings of the Royal Physical Society. 



Crustacea of the district were also contributed by me to the 

 Proceedings of the Royal Physical Society for 1890-94. 



Some months ago I decided to collect all the scattered 

 records of Forth Crustacea published by myself in the 

 Annual Eeports of the Fishery Board for Scotland and 

 elsewhere, and, adding those published by other writers, 

 or that have been supplied to me by friends interested in 

 the natural history of the district, to prepare a catalogue 

 of the land, fresh-water, and marine Crustacea known to

 records of species belonging to that group. 



Contribution by Dr and Miss Sprague. 



An excellent paper on the Fresh-Water Crustacea of Mid- 

 Lothiau, by Dr and Miss Sprague, published in the Trans- 

 actions oj the £di7iburgh Field Naturalists and Microscopical 

 Society in 1901, has also been very helpful to me. 



Contributions* by William Evans, F.R.S.E., and 

 Mrs Janet Carphin. 



Mr William Evans, F.R.S.E., Edinburgh, has added one or 

 two interesting species, notably the rare terrestrial Isopod, 

 Platyarthrus Hoffmannseggi, to the Crustacean fauna of the 

 Edinburgh district, and has also furnished me with a number
