CHEAT GREY TROUT. 63 



The fin-rays in number in this specimen from Loch Awe 

 were 



D. 13 : P. 14 : V. 9 : A. 11 : C. 19. 



The specimens examined from Lough Neagh had one 

 ray less in the dorsal, pectoral, and anal fins, and one ray 

 more in the caudal fin. For an excellent account of this 

 fish, see the article Angling in the seventh edition of the 

 Encyclopedia Britannica, from which I derive the following

 with markings of different sizes, and varying in number in 

 different individuals. In some these markings are few, scat-

 part of the fish ; it is marked with large dark spots ; the pec-
