HIGHER CRUSTACEA OF THE FIRTH OF CLYDE. 351 



Prof. Bell suggests that the Mysis integer briefly 

 described by Leach in the Transactions of the Linnean 

 Society, vol. xi., p. 350, is probably identical with 

 this species. In this paper it is stated that, "at 

 low tide, near Loch Ranza (in the Isle of Arran), 

 the pools were full of this species, STvininiing ^vith 

 its head uppermost, and its eyes spread, making a 

 most grotesque appearance." We have never met 

 with it in the district.
