organisms at one time, while at another time they preferred different 

 forms 1 Probably the food present on the ground determines, to some 

 extent, the kind of organisms that are to be found in the stomachs of 

 such fishes as are at least j^artly or wholly omnivorous. 



A sample of twenty small Dabs — some of them being under two inches 

 in length — were sent froni Annan on April 30th, 1900. The food of 

 this sample consisted of small lamellibranchs and other Molluscs ; Amphi- 

 pods such as Bafhyporeia sp., Corophium (jrossipes, and Gammarus ; and 

 a few Copepods,chiefly Eurytemora, were also observed, besides fragments 

 of Annelids, Zoophytes, etc., but nothing very particular was noticed. 



The stomachs of seven specimens from the Firth of Forth, collected on 

 ^lay 13th, 1901, contained several smsdl En pagicr us {1 cuanensis), several 

 Ampelisca sp., Stenothot marina, Paramphitlio'e monocuspis, Cheirocrates 

 intermedius, and DuUchia falcata, and also some remains of Annelids. 

 The names of all the species will be found m the list annexed : —

Flounder. Plewonectes Jlessus, L. 



A considerable number of Flounders obtained from the salmon fishers 

 at the Bay of Nigg have been examined, but the stomachs of most of 

 them contained only the remains of Annelids, which were usually too 

 much decomi)osed for identification, the only form recognised being the 

 common Lugworm {Arenicola). Of seven specimens obtained on ^larch 

 19th, 901, the stomachs of six did not contain anything that could be 

 identified, but the following organisms were obtained in the other one.
