1. SALMO. 57 



The pracoporculum has the hinder margin almost straight and 

 vertical, the angle rounded, and the lower limb distinct. The hinder 

 margin of the operculum is also nearly straight, oblique, and placed 

 at a rather obtuse angle to its lower margin. A line from the upper 

 end of the gill-opening to the angle of the operculum is longer than a 

 line from that point to the lower anterior end of the suboi)erculum. 



The distance of the origin of the dorsal fin from the occiput is a 

 little more than half an inch shorter than that of the hinder end of 

 that fin from the caudal. The dorsal fin is higher than long, and is 

 composed of fourteen rays, of which the first three are rudimentary 

 and enveloped in the skin, the fourth simple and slightly shorter 

 than the fifth, which is the first branched ray ; the last ray is cleft 

 to its base. The length of the base of the anal fin is rather more 

 than two-thirds of its height. The anal fin has twelve rays, the 

 first three of which are rudimentary and enveloped in skin, the fourth 

 being simple and nearly as high as the fifth, which is the first 

 branched and the longest ray of the fin ; the last ray is cleft to the 

 base. The length of the pectoral fin exceeds that of the space between 

 the orbit and the angle of the operculum by about one-fourth of the 

 length of that space. Ventral shorter, reaching about two-thirds of 

 the distance of its root from the vent ; its outermost ray is vertically 

 opposite the ninth of the dorsal fin. Caudal slightly emarginate. 



There are 120 transverse series of scales, counted immediately 

 above the lateral line ; the series extending obliquely backwards from 

 the first dorsal ray to the lateral line contains twenty-seven scales ; 

 that from the hinder end of the adipose forward to the lateral line has 

 fourteen scales, and there are twenty-four longitudinal series between 

 the lateral line and the root of the ventral. All the scales arc 

 rounded behind. 



Back brownish green; sides and belly silvery ; numerous roundish 

 reticulated black spots, of about the size of four scales, scattered on 

 the upper parts of the body ; several large ones on the opercidum ; 

 round spots of a bright orange-colour run along the lateral line, a 

 few being scattered below it. Dorsal thickly spotted with large, 

 elliptic, black spots, and with a black and yellow supero-anterior 

 margin. Pectorals and ventrals yeUow, with blackish margins. 

 Caudal and anal dusky, the latter with a black and yeUow anterior 

 margin.
