Deformed Trout are not uncommon ; mention of them 

 as occurring in some of the lakes of Wales is made by Pen- 

 nant, Oliver, and Hansard. " In 1829," says the writer of 

 the article on Angling in the seventh edition of the Ency- 

 clopsedia Britannica, " we received some very singular Trouts 

 from a small loch called Lochdow, near Pitmain, in Inver- 

 ness-shire. Their heads were short and round, and their upper 

 jaws were truncated, like that of a bull-dog. They do not 

 occur in any of the neighbouring lochs, and have not been 

 observed beyond the weight of half a pound." Such a Trout 

 from Lochdow was presented 

 to the Museum of the Zoolo- 

 gical Society by the Honour- 

 able TAviselton Fiennes : the 

 vignette is a representation 

 of the head of that specimen.
