February, 1905.—The stomachs of six herrings from a sample sent 
from Loch Fyne contained each a considerable amount of Calanus 
helgolandicus. 
July, 1905.—No more herrings from the Loch Fyne district were 
submitted for examination till July, when the stomachs of twenty-three 
specimens were examined. These form part of a sample captured about 
the end of April and retained during the interval in a cold storage 
chamber. All the stomachs contained food, and in most of them the 
quantity observed was considerable, and with two exceptions consisted 
entirely of Copepoda—Calanus helgolandicus being apparently the only 
species represented. In the two exceptions referred to the food 
consisted of post-larval fishes and Calanus, and my notes indicate that 
the food in these two was more decomposed than in the others, due 
probably to the presence of the young fishes. 
September 22nd, 1905.—The stomachs of eight herrings were examined. 
They were from a sample sent from Strachur, and captured two days 
previously. Two of them were considerably distended, but contained no 
food ; three contained some red-coloured matter, but there was nothing 
that could be identified ; ore was packed full with Calanus; in the 
other two there was some red-coloured stuff with fragments of Copepods 
mixed up with it. 
December 11th, 1905.—The stomachs of thirty-four herrings sent from 
Loch Fyne were examined. Sixteen were found to be empty, or con- 
tained some red-coloured matter probably derived from Calanus, but no 
trace, even of their appendages, could be detected. All the others 
contained the remains of Calanus, the specimens being in a number of 
eases tolerably whole, in others they were more or less fragmentary. 
There was also present in many of the stomachs a quantity of red- 
coloured oily matter derived probably from the Calanus. The fish 
whose stomachs contained food comprised 6 2 and 12, and the others 
79 and 6<¢. 
January, 1906.—The stomachs of twenty herrings sent from Strachur 
were, with one exception, found to contain food, which appeared to 
consist entirely of Calanus. Some of the stomachs contained a con- 
siderable quantity of food. The fishes comprised 11 9 and 8g. The 
empty stomach belonged to a male fish. 
September 8th, 1906.—Eleven stomachs from Loch Fyne herrings 
were examined at this date. One contained some food too much 
digested for identification. One contained Calanus, Centropages hamatus, 
Metridia lucens, and young Euphausiide. One contained Calanus, 
Centropages hamatus, Evadne nordmannii, and some Decapod larve, 
and another contained a small quantity of Calanus only. The food 
observed in five of the others consisted entirely of Vyctiphanes norvegica, 
while two contained the remains of Euphausiide which probably also 
belonged to Nyctiphanes, but they were too much digested to be 
satisfactorily determined. 
October 12th, 1906.—The eleven stomachs of Loch Fyne herrings 
examined at this date all contained food, in most cases in considerable 
quantity. The sexes represented comprised 9 9 and 24. The food 
observed in two stomachs consisted chiefly of Calanus, but Centropages 
hamatus, Temora longicornis, Oithona similis, and Decapod larve were 
also present. A small quantity of food, apparently all Calanus, was 
observed in another. A third contained a moderate quantity of Calanus, 
but Temora longicornis was also present. The food observed in other 
four appeared to consist entirely of Euphausiide, and were probably all 
Nyctiphanes—at least this was the only species that could be identified. .
