mens of fish as he once was able to do, both for Dr. Giinther and Mr. Couch, in times 

 gone by. 



The only localities for this species given by Giinther are Lough Eske, County Donegal, 

 and Lough Dan in the county of Wicklow. 



The following is a description of a male specimen I received on the 30th. of October, 

 1878: — Total length, from end of snout to bifurcation of the caudal fin, eight inches and 

 a half; greatest depth one inch and seven eighths; length of head one inch .seven eighths; 

 maxillary rather feeble, extending to the posterior orbit; pectoral fin free from the operculum, 

 acutely pointed, inner margin streaked with vermilion, length one inch and a quarter, con- 

 siderably shorter than the head ; ventral fin red, with distinct outer white margin ; anal 

 reddish, with outer white margin ; adipose slightly tinged with red ; tail deeply incised, 

 lobes pointed and of a reddish tinge; eye large; scales small. Colour of the head deep 

 olive black; back dark, with several small inconspicuous round Salmon-coloured spots above 

 the lateral line; spots below lateral line more distinct; sides brownish pink, or deep roseate 

 hue over silver; under part of jaws whitish; gill-covers somewhat silvery; belly a delicate 

 pink; scales small, but conspicuous. In this specimen the dark parr marks characteristic of 

 the young of the Salmonida; were visible. 



The fin-ray formula is 



Dorsal 14. 

 Pectoral 1 3 . 

 Ventral 9. 

 Anal I 2 . 



Salmo coin is readily distinguishable from 5". grayi by the comparative shortness of the 

 pectoral fin.

AM indebted to Mr. Alexander Scott, of Garrison, Lough Melvin, for several excellent 

 specimens, both male and female, of this beautiful Charr. They were caught in the month 

 of November; the males had not parted with all their milt, and in the ovaries of the females 

 a few eggs still remained. Little is known of the life history of this species ; it appears that 

 the female matures early, and when only five inches long has fully developed eggs of the
