of several of the Salmonidte, in this species are narrower and more 

 lengthened, The general spotting seldom extends below the lateral line, 

 and two dark spots on the gill-cover are a very constant mark." JARD. 

 According to Pennant, " the adipose fin is never tipped with red ; nor 

 is the edge of the anal white." 



This fish, which is common in many of the rivers of Wales and Scot- 

 land, as well as in some of those in England, has been regarded by dif- 

 ferent observers as the young, either of the Salmon, the Sea Trout, or 

 the common Trout. It is, however, now pretty well ascertained to be 

 a distinct species, always remaining of a small size. Is called in some 

 places a Parr, in others a Skirling or Brandling. Said, by Sir W. Jar- 

 dine, " to frequent the clearest streams, delighting in the shallower fords 

 or heads having a fine gravelly bottom, and hanging there in shoals, in 

 constant activity, apparently day and night." According to Dr. Hey- 

 sham*, the adult fish go down to the sea after spawning, which takes 

 place, as in the other migratory species of this genus, in the depth of 

 Winter.

LENGTH. From twelve to fourteen inches. 



DESCRIPT. (Form.) Elongated ; the line of the back nearly straight ; 

 profile sloping gently downwards from the nape: greatest depth about 

 one-fifth of the entire length : head contained five times and a half in the 

 same: snout short and somewhat obtuse: jaws nearly equal, except in 

 the spawning season, when the lower one becomes longest: teeth small 

 and sharp ; those on the vomer confined to the anterior extremity : eyes 

 moderate ; their diameter rather less than one-fourth the length of the 

 head ; the distance between them equalling twice their diameter : gill- 

 cover produced behind into a rounded lobe; the basal margin sloping 

 very obliquely upwards : lateral line arising at the upper angle of the 

 opercle, at first slightly descending, but afterwards nearly straight, its 

 course being a little above the middle ; scales small : dorsal a little before 

 the middle of the entire length ; the distance from the first ray to the 

 end of the snout, when measured behind, not reaching beyond the base 

 of the caudal ; of a somewhat triangular form, the posterior rays being 

 not more than half the length of the anterior ones; fifth ray longest, 

 equalling a little more than half the depth of the body: adipose so placed, 

 that two-thirds of the distance between the dorsal and caudal lie before 

 it, one-third behind it : anal commencing considerably beyond a vertical 

 line from the tip of the reclined dorsal: pectorals just three-fourths the 

 length of the head : ventrals beneath the middle of the dorsal ; in their 

 axillae a long narrow pointed scale, nearly half their own length :
