\YLING. 



Ul 



the colour of tlie body ; the dorsal fin varied with square 

 dusky spots on the membrane between the rays, the upper 

 part of the fin spotted and streaked with reddish brown. 

 The Grayling appears to become darker by age, and the 

 pectoral fins are reddish about spawning time, with small 

 black spots. 



Switzerland also produces Grayling ; I have therefore 

 selected for the vignette a view of Mont Blanc.
