It is now fully two years since I laid before this 

 Society the first contribution towards a List of the 

 Amphipoda and Isopoda of the Firth of Clyde and 

 West of Scotland, and, in preparing the second 

 contribution, additions, as a matter of course, were 

 more and more sparsely met with. To the former 

 list of 170 species, there are now added 60, many of 

 which are new to Scotland and some recendy new 

 to science. With few exceptions, they have all been 

 taken in the Firth of Clyde. 



In the preparation of this list, I have been greatly 

 indebted to the Rev. Canon Norman for his help ; 

 and to the Rev. T. R. R. Stebbing, who has determined 

 most of the critical species, and has carefully gone 

 over the whole of the manuscript before it has been 

 printed. Whatever merits it may contain are there- 

 fore due to him.
