508 Part III. — Twentieth Annual Report 



a number of the stomachs, while small Molluscan shells and fragments of 

 Starfishes and Foraminifera were obtained in onlj' one or two. The 

 Crustacea included representatives of nearly all the important groups, 

 except the Brachyura and the Schizopoda ; young Crcmtjon sp. (probably 

 C. allmanni) occurred in a few of the stomachs, but the Sympoda 

 (Hemilamprops rosea and others) were rarely noticed. On the other 

 hand, Amphipods, Ostracods, and Copepods were of frequent occurrence. 

 Amongst the Amphipods DuUchia monacantha and jiorrecta were the forms 

 most frequently met with, but 3fefopeUa nasufa and Gammaropds nanus 

 were also occasionally observed as well as one or two of the more common 

 species. Bijthocytliere sim2)le.c and Krifhn hartonensk were the two 

 Ostracod species most frequently obtained, while the Copepoda most com- 

 monly met with were Eetinosoma sarsi and Idya furcata. LeptognatTiia 

 brevirenm, one of the Isopoda-chelifera, was also found in one or two 

 stomachs. No trace of fish remains was observed in the stomachs of any 

 of this sample of small Haddocks. The stomachs of the larger Haddocks, 

 captured at the same place and on the some date as the smaller 

 specimens just referred to, contained food which was largely composed 

 of Crustacea, though not so exclusively as in the previous sample, 

 the grouping of the species was also somewhat different. The Sympoda 

 were more frequently represented, and the species belonging to this 

 group were more varied ; small shell-fish were more frequent, and 

 the remains of young fishes were also on one or two occasions obtained. 

 Decapods (Eiqjagwus sp., and Crangon allmanni) were only observed in 

 three of the twenty-four stomachs examined. Schizopods (Erythrops 

 serrata) occurred in three. Sympoda, comprising Hemilamprops rosea, 

 Leucon nasica, Eudorella truneafula, Diadylis eornufa, DiasfyloiJes 

 hiplicata, Campylaspis sp., etc., were obtained in at least sixteen stomachs. 

 Amphipoda, including amongst them the somewhat rare Metop)ella nasufa 

 and Aceros phyllonyx, were even of more frequent occurrence. No 

 Isopods were observed in the stomachs of this sample. The only Ostracod 

 observed was Philomedes interpuncta, which occurred once. Copepods 

 were also rarely met with, Rohertsonia tenuis being the only species 

 identified. Fully 75 per cent, of the stomachs contained partially 

 digested Annelids (Chsetopods), which in some cases were only identified 

 by the presence of their bristles. The MoUusca comprised both 

 Lamellibranchs and Gasteropods, but chiefly the former, and were repre- 

 sented by such forms as Scrohicularia sp., young Solen sp., and Philine. 

 The fish remains observed were chiefly those of young flat-fishes — a small 

 Long Rough Dab being one of those identified. 



Two samples of Haddocks — one consisting of twenty-five small 

 specimens ranging from 11 to 14f centimetres, and one of ten specimens 

 of average size, and collected about fifty miles south-eastward of Fair 

 Island — were also examined ; but as the contents of the stomachs of these 

 two samples resembled very closely those already described, both as to 

 the quantity and the variety of the organisms observed, it is not necessary 

 that a detailed description of them should be given ; a full list of the 

 organisms observed will be found in the annexed Table. 



Two Haddocks which were captured in the Clyde at Station IV. 

 (Kilbrennan Sound) in 18 to 20 fathoms on October 4th, 1899, gave the 

 following results: — One which measured 26^ centimetres in length had in 

 its stomach eighty specimens of NycHjjJumes norvegieus of an average 

 length of about 33 millimetres ; the stomach of the other, which was a 

 smaller fish and measured 22 centimetres long, contained one hundred 

 and eighty Nyctiphanes, the length of the majority of which Avas about 

 20 millimetres.
