One contained Calanus, Metridia lucent, another a small number of 

 Decapod larvae, while one contained the remains of a considerable 

 number of Euphausiida3 (Nyctiphanes probably), and a few post-larval 

 fishes which appeared to be sand-eels. 



November 9th, 1906. — The stomachs of four herrings from Loch 

 Fyne examined at this date contained a considerable quantity of food 

 which appeared to consist entirely of Calanus. The fishes com- 

 prised 2 2 and 2 J. 



December 18th, 1906. — A small sample consisting of the stomachs of 

 three Loch Fyne herrings (2 <j> and 1 tf) contained a small quantity of 

 food of a semi-fluid nature, but no trace of anything that could be 

 identified. 



(2). The Clyde. 



June 2nd, 1905. — Examined the stomachs of twenty-seven herring sent 

 from Campbeltown. One contained one or two fish scales, another was 

 filled with Nyctiphanes, and two contained some red- coloured matter with 

 fragments of Calanus mixed up with it; the others were either empty or 

 contained nothing that could be identified. 



July 3rd, 1905. — Examined the stomachs of thirty-six herrings also 

 from Campbeltown, but only five of them contained food that could be 

 determined even in a limited degree. These fishes had been captured on 

 11th March, and kept in a cold storage chamber. In one the food con- 

 sisted of Annelids (Chaetopoda) and Amphipoda (Hyperiidae), while the 

 other four contained the remains of Crustacea, apparently belonging to 

 Calanus. 



August 9th, 1905. — The stomachs of nineteen herrings from Pirnmill, 

 Kilbrennan Sound, were examined at this date, but captured on the 26th 

 of the preceding month. Seven were empty or did not contain anything 

 that could be identified. Ten contained food which appeared to consist 

 entirely of Schizopods (Euphausiidae), probably all Nyctiphanes not vegica, 

 — at least those specimens that could be satisfactorily distinguished 

 belonged zo that species. In one which contained only a small quantity 

 of Crustacean remains, the only species identified was Centropages 

 hamatus, while another contained Crustacean remains that could not be 

 determined with certainty. 



September 2nd, 1905. — Twenty-five stomachs of herrings from Carra- 

 dale were examined, but they had been captured on July 26th. They were 

 all empty, and many of them were distended with air. The fishes comprised 

 14 $ and 11c?. In several cases the stomachs were covered externally 

 with white clean fat. 



January 21st, 1906. — Eleven stomachs of herrings from Campbeltown 

 contained food that consisted chiefly of Nyctiphanes norvegica, some 

 Calanus being also present. Most of the stomachs were full, and some 

 were considerably distended by the large quantity of food they contained. 

 Five of the herrings were females and six males. 



December, 1906. — No further stomachs of herrings from the Clyde were 

 submitted for examination till December, when four from a sample 

 sent from Girvan and the same number from a sample from Rothesay 

 were examined. Those from Girvan all contained food that could be 

 identified. One contained a moderate quantity of food which appeared 

 to consist entirely of Calanus in a fragmentary condition. One contained 

 Euphausiidaa very much digested, while the food observed in the other 

 two consisted of Euphausiidae and Calanus. 



Three of those from Rothesay contained only a small quantity of food, 

 which consisted entirely of Calanus, and the other was well filled with
