Remarks,—The Ostracoda 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 Algz 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.
