Mr. G. Sim, of Aberdeen (Edinburgh Prize Essays 

 Fish Exhibition, 1882), found in the stomachs of those he 

 examined, the young of their own kind, also of sprats. Of 

 stalk-eyed Crustacea, examples of Galatkea, Mysis, Thysa- 

 noessa, Thysanopoda and Acanthocaris, several larval forms 

 of Brachyurus, some of which were very abundant. Of 

 sessile-eyed Crustacea, Hyperia, Lestrigonus, and one species 

 of jEga. Of Entomostraca, Cythere, Temora, and Evadne. 

 Of the foregoing, Hyperia and a young univalve mollusca, 

 Sagitta bipunctata^ ? ), Mysis spiritus, and young herrings 

 and sprats formed the largest portion of their food, the last 

 two being most abundant from December until May. 

 From May until October, Temora longicornis is their most 

 common food, and from December till February, Hyperia 

 galba and Sagitta bipunctata. The other forms of animal 

 life, it appeared to him, might be classed as a sort of chance 

 food, while, although two species of sessile-eyed Crustacea, 

 Amathilla Sabini and Atylus Swammerdamii, swarmed 

 along the coast, he never found either in the stomach of 

 the herring. Mr. Sim points out how similar in external 

 appearance is the Hyperia galba on which it feeds, to A tylus 

 Swammerdamiiy which it rejects, and suggests whether 

 taste or smell may not exercise an influence. 



The food of the herring varies in accordance with what 

 most desirable form exists at the locality which it frequents, 

 and it devotes its attention to the young of fishes, or of its 

 own kind, or of the sprat ; the young of the sand launce, 

 and likewise of a small gobioid along our southern coast. 

 Stalk-eyed, sessile-eyed Crustacea, and entomostraca, 

 afford it nourishment, and Acalepha have also been 

 detected in its stomach. As it appears to exercise selection 

 in the forms it devours as food, it is probable that it 

 would follow such to wherever they migrate, as along our
