512 Part III. — Tv^cntieth Annual Report 



in the third a few Copepods were found which could not be satisfactorily 

 determined ; the fishes in this sample ranged from 14^0 to 181 centi- 

 metres in length. 



The stomachs of all the nineteen specimens from the Shetland 

 district contained food which consisted almost entirely of the remains 

 of Crustacea, but they were so much decomposed that it was with 

 difficulty the following organisms could be recognised: Hemilamjyrops 

 rosea and a few Mysid^e were found in two stomachs ; Grangon allmanni, 

 Halimedon 'parvimamis, and one or two other Amphipods — the genus and 

 species of which were doubtful — were found in two. Copepods, including 

 Calanus finmarchirus, Temora longicornis, and Metridia lueens occurred 

 in at least nine of the stomachs, and the remains of small fishes in one. 

 The viscera of these fishes was very oily, more so than those of any of 

 the others examined. 



The food observed in the Moray Firth specimens was largely composed 

 of young Crustacea belonging to the Macrura; they occurred in the 

 stomachs of every one of the twenty specimens examined ; Ccdanus fin- 

 marchicus was also obtained in all these stomachs, but it was not so 

 numerously represented as were the young forms I have mentioned. 

 Other Copepods, such as Temora longicornis, Metridia lueens, and Gentro- 

 jjagus typieus, were occasionally noticed, as also were Eupagurus sp., 

 Grangon sp., Hyperia galha, and Parathemisto obUvia. lb will be 

 observed that the organisms which constituted the chief part of the food 

 of these Norway Pouts from the Moray Firth were more truly pelagic 

 in their habits than the organisms which constituted the food of the 

 Haddock, but whether this difi'erence is the result of necessity or choice 

 it would at this stage be difficult to say. 



The food observed in the stomachs of the sample collected in the 

 deep water off Aberdeen consisted chiefly of Sagitta and Galanus finmar- 

 cliicus ; Temora occurred in eight of the ten stomachs examined, and 

 Pseudocalanus elongatus in one ; Argissa hamatipes was found in two, 

 while Gastrosaccus spinifer and Pseudocuma (?) cercaria were each 

 observed in one. One stomach contained matter too imperfect for 

 identification. No young fishes, Mollusca, nor Starfishes were found in 

 any of the stomachs of this sample ; but the organisms of which the 

 food was composed, though differing somewhat markedly from those 

 composing the food of the Moray Firth sample, were forms which, like 

 them, were more or less distinctly pelagic. It will be understood that in 

 these remarks on the differences observed in the food of the different 

 samples the reference is not so much to individuals, but rather to the 

 group of species composing the food. Thus the food of the Moray Firth 

 specimens consisted chiefly of young Macrura and Galanus, to which were 

 added a few other forms, such as Metridia lueens and Temora longicornis, 

 the former being the more frequent of the two. In the food of the 

 Aberdeen sample, on the other hand, the young Macrura are replaced by 

 Sagitta, and Temora is about equal to Galanus in frequency and quantity, 

 but Metridia is altogther absent ; moreover, in place of Grangon and the 

 Hyperoidce we have Gasterosaccus, Pseudociima, and Argissa, yet the 

 organisms composing the food in both samples are mainly pelagic forms. 



The following list contains the names of all the species observed so 

 far as they could be identified : —
