 OF THE FIRTH OF CLYDE.

The Crustacea of the Firth of Clyde have hitherto 

 received but scant attention, no list having as 

 yet appeared which treats of the higher forms found 

 in this important estuary. A list of the Ostracoda 

 is given in the Fauna and Flora of the West of 

 Scotland, published during the meeting of the British 

 Association at Glasgow in 1876 ; and the author, Mr. 

 David Robertson, has since made considerable addi- 

 tions to this* ; indeed, from the careful manner in 

 which this indefatigable naturalist has explored the 

 district in search of these minute organisms, there 

 is perhaps no similar area in Britain which can show 

 a larger number of recorded species. Mr. Robertson 

 has also for many years paid special attention 

 to the Amphipoda, and is engaged at present in 

 preparing a list, which, along with many interesting 

 observations on the habits of the members of this 

 group, cannot fail to be of value to subsequent 

 workers. Dr. G. S. Brady records several Clyde 

 species in his Monograph of the Free and Semi- 

 Parasitic Copepoda of the British Islands, one of the 

 more recent publications which we owe to the Ray 

 Society. 



As regards higher Crustacea, the work previously 

 done in the district may be briefly alluded to. In 



* See his later work on the AVest of Scotland Ostracoda, 

 forming one of a series of papers on the Fauna of Scotland 

 published by the Glasgow Natural History Society.
