VI.—SOME FURTHER OBSERVATIONS ON THE FOOD OF 
FISHES, WITH A NOTE ON THE FOOD OBSERVED IN THE 
STOMACH OF A COMMON PORPOISE. By Tuomas Scort, 
BoD. BLS. 
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. 
Sebastes norvegicus (Ascan.). 
Trigla gurnardus, Lin. 
Lampris lune (Gmelin). 
Anarrichichas lupus, Lin. 
Lumpenus lampetreeformis 
(Walbourn). 
Mugil chelo, Cuvier. 
Labrus mixtus, Lin. 
Gadus luscus, Lin. 
» esmarkii, Nilsson. 
Molua molva, Lin. 
Onos cimbrius, Lin. 
Ammodytes tobianus, Lin. 
Drepanopsetia plattessoides (Fabr.). 
Pleuronectes cynoglossus, Lin. 
Argentina sphyrena, Lin. 
»  stlas (Ascanius). 
Raia batis, Lin. 
», Jullonica, Lin. 
5, vradiata, Donovan. 
» circularis, Couch. 
Squalus acanthias, Lin. 
Scylliorhinus canicula (Lin.). 
Their names are as follow :— 
The Norway Haddock. 
The Grey Gurnard. 
The King Fish. 
The Cat or Wolf-fish. 
The Sharp-tailed Lumpenus. 
The Grey Mullet. 
The Striped Wrasse. 
The Whiting Pout or Brassie. 
The Norway Pout. 
The Ling. 
The Four-bearded Rockling. 
The Lesser Sand-eel. 
The Long Rough Dab. 
The Witch-sole. 
The Hebridean Smelt. 
The Greater Argentine. 
The Grey Skate. 
The Shagreen or Fuller’s Ray. 
The Starry Ray. 
The Cuckoo or Sandy Ray. » 
The Picked Dog-fish. 
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 117, 113, and 124 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 ‘t consisted of 
Crustaceans, shell-fish, or fish, even considerably digested, the remains of 
the harder parts, or some of them, would have afforded an Bese of 
the nature of the food.
