IX.-OBSEKYATIONS ON THE FOOD OF FISHES. 

 By Thomas Scott, F.L.S., Mem. Soc. Zuol. de France. 



The observations contained in the present paper refer chiefly to the 

 food of small or immature fishes, but reference to a few large gadoids, 

 congers, and others are also included. It may be explained that during 

 the past two or three years my attention has, to some extent, been 

 devoted to the investigation of the ecto- and ento-parasites of fishes, and 

 in connection with this it was generally found necessary that an examina- 

 tion should be made of the stomachs as well as of the other parts of the 

 fishes which had been handed over to me for that purpose, and 

 frequently while a search was being made for Entozoa separate notes of 

 the food observed in the stomachs were also taken. In this way, as well 

 as by the examination of fishes set apart for the special purposes of this 

 paper, a considerable number of notes on the food of fishes have been 

 collected. 



The number of fishes dealt with in this paper reaches to considerably 

 over two thousand, and includes representatives of fifty-six species and 

 thirty-seven genera.* Their names are as follow.
