382 Proceedings of the Royal Physical Society. 



The following two species are additions to my list, viz., 

 Peltocoxa Mario7ii, Catta, and Cressa minuta, Boeck, both being 

 recorded from the Forth. This raises the total to 796. 



I need scarcely add that this important work, by one of 

 the foremost of living Carcinologists, is indispensable to those 

 engaged in the study of the Amphipoda. 



Before closing I desire to take this opportunity to express 

 my indebtedness to Mr William Evans, F.R.S.E., President of 

 the Eoyal Physical Society, for the whole-hearted assistance 

 he has given me while this Catalogue was passing through 

 the press. I am also not forgetful of other friends who have 

 shown an interest in my efforts to make this contribution to 

 Scottish Natural History, unpretentious though it be, of some 

 use to students of the Crustacea of Scotland.
