265 Part III.—Twenty-fifth Annual Report 
1905 ; a considerable proportion of them were entirely empty, a number 
of the others contained some red-coloured fluid, probably derived from 
organisms captured by the fishes, but there was nothing that could be 
identified. In several instances the stomachs were distended with air, 
the result perhaps of fermentation. The fishes represented by these 
stomachs comprised 29 9 and 20g. 
June 1st,1905.—-Thirty-six stomachs of herrings sent from Loch Broom 
were examined at this date. The results obtained resembled generaily 
those of the previous sample. A number of the stomachs were found to 
be entirely empty, and theothers contained some semi-fluid matter usually 
of a reddish colour, but no trace of anything that could be identified 
with certainty. In some cases, as in the previous sample, the stomachs 
were considerably distended with air. 
(4) Srornoway. 
June, 1905.—The stomachs of thirteen herrings, being part of a sample 
sent from Stornoway on May 19, were examined in June. They all 
contained food which, with one exception, consisted for the most part 
of post-larval fishes. In the one stomach referred to, however, no fishes 
were observed, but the food consisted entirely of Decapod larve, of which 
there were a considerable quantity. Eight stomachs contained fishes 
only, while the others contained both fishes and crustacean larve. The 
fishes appeared to be mostly sand-eels, but Clupeoids may, in some cases, 
have also been present; the food, however, had already undergone 
digestion to some extent, and the species could not in a few examples be 
satisfactorily determined. One stomach at least was crammed full with 
post-larval sand-eels, and two others were fairly well filled with the same 
kind of fish. The only other organism observed in addition to the Deca- 
pod and fish larve was a single specimen of Caligus rapax. All the 
thirteen herrings were females with undeveloped ovaries. 
July 7th, 1905.—The stomachs of thirty-four herrings seut from 
Stornoway were examined. Hight of them were either empty or contained 
a small quantity of semi-fluid matter, but nothing that could be identified. 
The other twenty-six contained food which consisted for the most part of 
post-larval fishes, chiefly sand-eels. In only two examples were fish 
remains apparently absent, and the food in one of these consisted of the 
remains of Calanoida and in the other of Euphausiide, but these organ- 
isms were so much disintegrated that the species could not be satisfac- 
torily determined. 
Eight stomachs were distended with the large quantity of young fishes 
they contained, while as many more were tolerably well filled with them. 
In a few cases Calanus were found in the same stomachs with the fishes. 
Seven of the thirty-four herrings were spawners, but there was no indica- 
tion that difference in sex resulted in any difference in the nature or 
quantity of the food consumed. 
January 17th, 1907.—The stomachs of two herrings (? and ¢)—part of 
a sample from Stornoway—contained each a small quantity of food 
consisting of fragments of Schizopods (Euphausiide) ; they were so 
disintegrated as to be almost indistinguishable, but the only fragments 
that could be identified with certainty belonged to Nyctiphanes. 
February 14th, 1907.—Six herrings (5 2 and 1 Q), from another sample 
sent from Stornoway, had all of them food in their stomachs. Two were 
tolerably full, but the quantity in the others was small. One contained 
post-larval fishes—apparently Clupeoids, but the food observed in the 
ethers consisted only of Vyctiphanes.
