VI.— SOME FURTHER OBSERVATIONS ON THE FOOD OF 

 FISHES, WITH A NOTE ON THE FOOD OBSERVED IN THE 

 STOMACH OF A COMMON PORPOISE. By Thomas Scott, 

 LL.D., F.L.S. 



In my paper on the food of fishes published in Part III. of last year's 

 Report,* I gave the results of the examination of fishes belonging to fifty- 

 six different species. In the present paper twenty-two species are repre- 

 sented, sixteen of which are teleosteans and the others Rays and Dog- 

 fishes. Their names are as folknv : — 



Sebastes norvegicus (Ascan.). The Norway Haddock. 



Trigla gurnardus, Lin. The Grey Gurnard. 



Lampris luna (Gmelin). The King Fish. 



Anarrichichas lupus, Lin. The Cat or Wolf-fish. 



Lumpenus lampetrceformis The Sharp-tailed Lumpenus. 



(Walbourn). 



Mugil chelo, Cuvier. The Grey Mullet. 



Labrus mixtus, Lin. The Striped Wrasse. 



Gadus luscus, Lin. The Whiting Pout or Brassie. 



„ esmarkii, Nilsson. The Norway Pout. 



Molua molva, Lin. The Ling. 



Onos cimbrius, Lin. The Four-bearded Rockling. 



Ammodytes tobianus, Lin. The Lesser Sand-eel. 

 Drepanopsetta plattessoides (Fabr.). The Long Rough Dab. 



Pleuronectes cynoglossus, Lin. The Witch-sole. 



Argentina sphyrmna, Lin. The Hebridean Smelt. 



„ silas (Ascanius). The Greater Argentine. 



Rata batis, Lin. The Grey Skate. 



„ fullonica, Lin. The Shagreen or Fuller's Ray. 



,, radiata, Donovan. The Starry Ray. 



„ circularis, Couch. The Cuckoo or Sandy Ray. 



Squalus acanthias, Lin. The Picked Dog-fish. 



Seylliorhinus canicula (Lin.). The Lesser Spotted Dog-fish or 



Rough-hound. 



These fishes are referred to in the sequel in the order in which they are 

 given here. 



At the end of the notes on the food of these fishes I describe the 

 results obtained by the examination of the food found in the stomach of 

 a common Porpoise cast ashore last year in the vicinity of the Laboratory. 



Sebastes norvegicus (Ascanius). 



Three Sebastes, measuring 11 J, 11 J, and 12 J inches respectively, and 

 captured in the North Sea in December 1901, had apparently been all 

 feeding on soft animal substances (probably Annelids), for though 

 each of their stomachs contained a quantity of food, there was nothing 

 to show satisfactorily what it consisted of. Had it consisted of 

 Crustaceans, shell-fish, or fish, even considerably digested, the remains of 

 the harder parts, or some of them, would have afforded an indication of 

 the nature of the food.
