ROACH AND RUDD. 259 
All the foregoing observations on Roach fishing apply 
equally to fishing for Rudd. 
Roach and Rudd will both take a fly occasionally in 
hot weather, and when basking at the surface. Any 
small black fly will take if the fish will: but the latter 
occurrence is so uncertain that fly-fishing for Roach 
cannot be recommended under ordinary circumstances. 
There are three other species belonging to the same 
genus as the Roach, viz. the “Double Roach,” the 
“Graining,” and the “ Azurine,” or Blue Roach. These 
species, however, are either confined to a few particular 
localities, or are so rarely met with as to pertain rather 
to the department of the ichthyologist than that of the 
fisherman. An account of their habits and characte- 
ristics will be found in the “ Angler-Naturalist.”
