To William Thompson, Esq. of Belfast, one of the Vice- 

 Presidents of the Natural History Society of that town, 

 I am indebted for many valuable and interesting notices of 

 the fishes of the Irish lakes and coast which are distributed 

 in various parts of this work. In 1835, Mr. Thompson 

 made the following communication to the Zoological Society 

 of London, which is published in the Proceedings for that 

 year, at page 78.
