ceiitimelres, a Long Rough Dab, Drepanopfetta jjlatesgoides (Fabr.), 

 measuring 19 centimetres in length, was obtained; while in the stomach 

 of the Dab portions of several young Portunus sp. were found. Several 

 specimens of a cestoid parasite {Ahothriuvi) were obtained in the 

 intestines of this Cod, but each pai-asite had its head inserted into one of 

 the caecal tubes. The stomach of another cod from the Fish Market, 

 measuring 89^ centimetres, and examined on November 6th, contained 

 three adult Norway Lobsters (Nei^lirops norvegicus), a small Lucina (?) 

 sjiinifera, and a fragment of a Cardiunt, while the stomach of another 

 specimen about 82i centimetres, captured in Aberdeen Bay on November 

 29th, 1901, contained one Haddock about 16| centimetres in length, the 

 remains of some other fishes, and a considerable portion of the body 

 of a large Buccinum undatum with the operculum attached. 



The following is a tabulated list of species which the Cod, referred to in 

 the preceding notes, had captured in the way of food.

The stomachs of one hundred and twenty Haddocks have been 

 examined for the purposes of this paper ; fully 78 per cent, of these 

 specimens were collected south-eastward of the Shetland and Fair Islands, 

 about 17^ per cent, are from deep water — 58 to 65 fathoms — about 10 

 miles off Aberdeen ; of the other specimens, two are from the Clyde and 

 two from the Moray Firth. 



Fifty-five of the Haddocks from the Shetland district were collected 

 65 miles south east of Sumburgh Head, on September ith, 1900; thirty-one 

 of them ranged from 8 to 11 centimetres (3i to scarcely 4| inches) in 

 length, but the other twenty-four were of average size. The stomachs 

 of the thirty-one small specimens contained food which consisted for the 

 most part of small Crustacea ; the remains of Annelids were observed in
