428 PISCES (OSSEI) MALACOPT. [SALMO. 



(Colours.) Back, and upper part of the sides, bluish gray, tinged with 

 olivaceous; flanks and belly flesh-colour: above the lateral line spotted 

 with white; beneath the same, spots more obscure: dorsal, anal, and 

 caudal, dusky, the latter darkest; pectorals and ventrals dark red. In 

 the spawning season, the flanks and abdomen are bright crimson-red; 

 the whole of the sides, above and below the lateral line, spotted with 

 deeper red ; the anal, pectorals, and ventrals, are also deep red, the first 

 rays of the anal and ventrals excepted, which are bluish white. 



Found in the lakes of Cumberland and Westmoreland, especially in 

 Winander Mere, in the latter county ; also in Crummock and Coniston 

 Waters in Lancashire, and, according to Sir W. Jardine, in many of the 

 northern lochs of Scotland. Frequents clear and deep waters, keeping 

 near the bottom. Feeds on insects. Varies much in its colours at dif- 

 ferent seasons, a circumstance which has obtained for it several different 

 names. In its ordinary state, it is the Case Charr of Pennant and other 

 authors : when exhibiting the bright crimson belly which it assumes 

 before spawning, it is called Red Charr : when out of season, the spawn 

 having been shed, it is distinguished by the name of Gilt Charr. Obs. 

 According to Agassiz, the S. Umbla, the S. Salvelinus, the S. alpinus, 

 and the S, Salmarinus, of LinnaBus, are all referable to this species in its 

 different states. 



110. S. Salvelinus^ Don. (Torgoch.) Vomerine teeth 

 confined to the anterior extremity : dorsal exactly in the 

 middle of the entire length : anal commencing in a line 

 with the tip of the reclined dorsal : axillary scale not one- 

 third the length of the ventrals. 



S. Salvelinus, Don. Brit. Fish. vol. v. pi. 112. 



LENGTH. Six inches. 



DESCRIPT. (Form.) Differs from the last species as follows: not so 

 much elongated in proportion to its depth: head larger; contained not 

 more than four times and a half in the entire length : teeth, those on 

 the tongue especially, stronger and more developed : eyes larger ; their 

 diameter rather more than one-fourth the length of the head ; the dis- 

 tance between them not equalling above one diameter and a half: pos- 

 terior lobe of the opercle not so much produced : all the fins relatively 

 larger : dorsal exactly in the middle of the entire length ; the distance in 

 front, when measured behind the fin, reaching to the end of the caudal ; 

 fifth and sixth rays longest, equalling at least three-fourths of the depth 

 of the body ; posterior portion of the fin very little less elevated than the 

 anterior: adipose nearer the middle point between the dorsal and the 

 caudal : anal commencing exactly in a line with the tip of the reclined 

 dorsal : pectorals longer : scale in the axillae of the ventrals much shorter, 

 not one- third the length of the fin :

(Colours.) Probably as variable as in the last species. The following 

 were those of the specimens examined : head, back, and upper part of 

 the sides, dark olivaceous-green; lower part of the sides yellowish, passing 

 into bright orange-red on the abdomen: above the lateral line spotted 

 with yellowish white; yellow of the sides, beneath the lateral line, spotted 

 with red: dorsal, caudal, and pectorals, dark olivaceous; first and last
