32S THE FJiE.SH-WATEK FISHES OF EUKOPE. 



Salmo carbonarius (Stronn). 



Mi: Lloyd tells us of a Cluirr, found only in Lake Sigdal, in Norway, which 

 the })e()ple distinguish as G'a/is/i?*^'*^-, characterised by its small eyes, blunt white 

 snout, and inflated belly, which led Nilsson to distinguish it as S. renfricosas. 

 It reaches a length of a foot, and is taken with the hook in winter. Dr. Giinther 

 regards it as identical with the fish f(nuKl in the wooded lakes of "Western 

 Norway, which the people name the KcUiiiuml. 



The latter has a soft, white, insipid Hesh, and is taken in the summer with 

 a bait of live frogs ; but it lives in deep water, and does not come to the sur- 

 face, even to spawn. The only difference from H. rentricosna is apparently the 

 absence of the abdominal inflation. The head and upper parts are black, the 

 sides grey, with small round white spots ; the under parts are white, and the 

 tins black, though the ventral and anal fins have white margins. Nothing is 

 known of the scales, internal anatomy, or other characters. 



Salmo grayi (Gunther). 



D. L-3— II, A. \-l, P. 1:3—1 1, V. 9. Scales : lat. line l^o. 



Lough Melvin, in the north-west of Ireland, between Ulster and Con- 

 naught, yields a peculiar Charr, with sixty vertebrte, and thirty-seven [)yloric 

 a})pendages, first recognised and described by Dr. Giinther. He finds it to be 

 eleven inches long, with the head and body compressed, and the dej)th at the 

 origin of the dorsal fin one-fourth of the total length. 



As in the English Charr, the snout is slightly compressed, sub-conical, 

 and longer than the diameter of the eye,, which is one-fifth of the length of 

 the head. The frontal space between the eyes, as in the Charr of Winder- 

 mere, is convex, with a median ridge, two series of pores, and similar width. 

 The nostrils are a little more distant from the eye. The maxillary bone has 

 sixteen small teeth, with those at the back rudimentary. All the other teeth 

 are small, and slightly fewer than in the English Charr, being four in the pre- 

 maxillary, twelve in the mandible, two to four on the vomer, fifteen on the 

 palatine bone, and four pairs on the tongue. The two or three outer branchio- 

 stegal rays are exposed laterally, as in the Welsh Charr. The lower branch of 

 the outer branchial arch has only nine straight lanceolate gill-rakers, instead 

 of thirteen, as in that fish. 



The dorsal fin commences a little farther forward, and its base is a 

 little longer. The base of the pectoral fin is not overlapped by the oper-
