a short distance from the shores, and are at this season taken 

 in some plenty by a poor cottager who resides in the vicinity 

 of the lake, and derives a small annual profit from the 

 fishery ; this delicious fish being in much request for the 

 tables of the neighbouring gentry." 



I am indebted to the kindness of the Rev. F. W. Hope 

 for specimens of the Welsh Charr from a locality near Bar- 

 mouth in Merionethshire, unnoticed by Mr. Donovan, but 

 recorded by Willughby. The piece of water is called Coss- 

 y-gedawl the lake of the fruitful marsh.* This fish is cer- 

 tainly identical with that of Llyn Cawellyn, and distinct 

 from the Charr of the Northern lakes of England. I have 

 not seen specimens of the Charr of the various lakes of 

 Scotland or Ireland, but have here endeavoured to furnish 

 the means of identifying them. The name bestowed by Mr. 

 Donovan is retained, till the Continental name, if it has one, 

 can be ascertained : I have, however, some reason to believe 

 that this species is unknown on the Continent. 



The length of the head compared to the length of the 

 head and body is as one to four ; the depth of the body 

 equal to the length of the head : the commencement of the 

 dorsal fin is half-way between the point of the nose and the 

 origin of the upper caudal rays ; the posterior edge of the 

 adipose fin is half-way between the commencement of the 

 dorsal fin and the end of the longest upper caudal ray ; the 

 longest dorsal fin-ray as long again as the base of that fin : 

 the pectoral fin large ; the ventral fin originates half-way 

 between the posterior edge of the orbit of the eye and the 

 end of the fleshy portion of the tail ; ventral axillary scale 

 small, not one- third the length of the fin ; the longest anal 



* The meaning of this term is said to be questionable : the primitive from 

 which it is derived means gift, relief, or profit. By Willughby it is spelt Casa- 

 geddor ; by others, Cors-y-gedol.
