 SCOTTISH SEAS. 



By Thomas Scott, LL.D., F.L.S., etc. 



(Plates X.-XIII.) 



Preliminary Note. 



The Crustacea mentioned in the following notes were obtained for the 

 most part in collections made during various Fishery investigations 

 carried out under the direction of Dr. T. Wemyss Fulton, Scientific 

 Superintendent of the Fishery Board for Scotland. 



Several of the forms described appear to be new to science, others have 

 not before been recorded from the Scottish seas, and one or two belong 

 to a curious parasitic group of minute Copepoda found usually in the mar- 

 supium of Crustacean species belonging to the Amphipoda, Sympoda, and 

 others of the smaller Malacostraca. 



The following are the species described : — 



Pseudocyclopia giesbrechti, Wolfenden — male described for the 



first time.
