 in which no Bream exist, and that the Bream-flat 

 has been recognized only in a comparatively few 

 rivers, whilst in hundreds Roach and Bream co- 

 exist plentifully together, without either Rudd or 

 Bream-flats. 



The Rudd is the " Shallow " of Cambridgeshire, 

 the " Roud " of Norfolk, and the " Roach " (that is 

 the fish commonly so-called) of Ireland.

 in the water. It is also remarkably tenacious of

 Rudd it is placed considerably further back. In
