fin half-way between the origin of the last dorsal fin-ray and 

 the end of the longest caudal ray ; the longest dorsal fin-ray 

 but one-fourth longer than the base of that fin : the pectoral 

 fin small ; the ventral fins originate half-way between the 

 point of the nose and the commencement of the under caudal 

 rays ; the ventral axillary scale nearly half as long as the fin ; 

 the anal fin small, the longest ray but little longer than the 

 base of the fin ; the tail deeply forked, the longest rays more 

 than as long again as those in the centre ; all the fins of 

 small comparative size. The fin-rays in number are 



D. 13 : P. 12 : V. 9 : A. 11 : C. 19. Vertebrae 59. 



The diameter of the eye is less than one-fourth of the 

 length of the whole head ; it is placed at the distance of one 

 diameter from the point of the nose : the teeth small ; a few 

 on the anterior part only of the vomer ; the other four rows 

 above and four rows below, as usual in the fishes of this 

 genus. The branchiostegous rays vary from ten to twelve, 

 and frequently differ in number on the two sides of the head 

 of the same fish. 



The top of the head and all the upper parts of the back 

 umber brown ; the sides lighter ; the whole of the belly, 

 pectoral, ventral, and anal fins, deep reddish orange ; the 

 first ray of the ventral and anal fins white ; the sides above 

 and below the lateral line marked with numerous red spots ; 

 the irides orange ; gill-covers yellowish olive ; dorsal and 

 caudal fins dark brown, tinged with purple brown ; the lateral 

 line straight, but rising gradually from the parallel of the 

 point of the pectoral fin to the top of the operculum ; the 

 scales very small, more than thirty in an oblique line from 

 the base of the dorsal fin to the lateral line, and as many 

 from the ventral axillary scale upwards to the lateral line. 

 In this state as to colour, this fish is considered to be the 

 S. safvelinus of authors.
