Remarks. — The Osfcracoda are not so important as the Copepoda as a 

 source of food for fishes. Only in a very few instances have I noticed 

 them among the contents of fishes' stomachs, and these were the 

 stomachs of ground feeders, such as haddock and cod, and the only species 

 of Ostracod observed was the one last recorded in the preceding list, viz., 

 Philomedes interpuncta. The young of Balanus in an early stage (the 

 Ostracod stage) are frequently found in the stomachs of herring and other 

 fishes, and are liable to be mistaken for a species of Ostracod, which may 

 account for such Entomostracans being recorded as occurring in the con- 

 tents of fishes' stomachs more often than is really the case. Most of the 

 species live on or in the mud at the bottom, or among the Algse and 

 Zoophytes which grow there within certain limits. 



A small Entomostracan, Evadne Nordmannii, Loven, is frequently 

 noticed among the material collected by the surface-net in the seaward 

 part of the Forth, but not in so great abundance as it occurs in the Firth 

 of Clyde, the stomachs of herring taken there being sometimes found to 

 contain considerable numbers of these organisms. Whether the herring 

 purposely seek for and capture them, or whether they are swallowed in 

 a sort of indiscriminate way, as suggested by Dr Mobius, has not been 

 satisfactorily ascertained.
