Mcintosh in regard to certain fisheries on the east coast of 

 England and Scotland.* 

 Invertebrates taken in the trawl net. 



No special attention was paid to the bottom inverte- 

 brate fauna, but the following forms were identified among 

 the contents of the net : — 



Mytilus modiola, Alcyonidium, various compound and 

 simple ascidians, Flustra, Pecten, Asterias, Solaster, Astro- 

 pecten, Echinus, Cucumaria frondosa, Ophioglypha, Fusus, 

 Dentalium, Hi/as, Stenorhyncus, Pagurus, Portwnus, Porcel- 

 lana, Aphrodite, Sabella and other Polychaetes, and Actino- 

 loha. Pontobdella (from a ray) was also taken. Zostera was 

 present in the North Western portion of the bay. A female 

 lobster of 8f inches in length was caught in the first haul, 

 and two females, one recently berried, 10 inches in length, 

 were obtained in the third haul. 

 Food of the fishes taken. 



The majority of the fishes were examined for food 

 contents of the stomach. Ray were feeding on fishes (too 

 much decomposed for identification) ; plaice and dabs on 

 Scrobicularia and Nucula (especially the latter), and the 

 soles on annelids with a few Serobicularia. 



Plankton. 



Surface tow-nettings were taken during every haul 



except the last. The pelagic organisms present were, 



however, remarkably scarce (not more than 10 cc. in all 



the five hauls), and the only animals present were Pleuro- 



brachia (relatively abundant), Caligus rapax (male), a 



young Cyclop)terus lumpus, some larvse decapods, and the 



Copepods P'aracalanus parvus, and Oithona similis. This 



is in marked contrast with the fishing operations in 



October, 1902, when an enormous catch of Copepods (over
