the following ray, which is also simple ; the fifth is the first branched 

 ray, the terminal ray cleft throughout. 



The anal fin is higher than long, and consists of eleven rays, of 

 which the two anterior ones are rudimentary, the third simple, the 

 fourth and fifth are branched and the longest rays of the fin, whilst 

 the final ray is cleft throughout. Pectoral as long as the postorbital 

 portion of the head, reaching two-fifths of the distance of its root 

 from that of the ventral ; ventral shorter than the pectoral, reaching 

 more than half the distance of its root from the vent ; its outermost 

 ray is vertically opposite the tenth of the dorsal fin. 



Posterior margin of the caudal fin scarcely emarginate. 



There are 117 transverse rows of scales, counted immediately 

 above the lateral line; the series descending obliquely from the 

 origin of the dorsal fin to the lateral line contains twenty-eight 

 scales; that from the hinder end of the adipose forward to the 

 lateral line has fourteen scales. There are twenty-two series be- 

 tween the lateral line and the root of the ventral. 



Back and upper parts of the side dark purpHsh, with numerous 

 irregularly X-shaped black spots ; the remainder of the body silvery, 

 each scale being suiTounded by minute brown dots; sides of the 

 head and dorsal fin with a few small, round, black spots. Caudal 

 inner side of pectoral and ventral, blackish. 



Pyloric appendages fifty-eight.

Peal, Salmon-Peal. Specimens sent to us under this name are 

 identical with the Sewin. The account of the habits of this sup- 

 posed species, given by Couch (Z. c. p. 200), is compiled from his 

 own observations and from those of other authors ; but there is no 

 evidence to show that they refer to one and the same fish. The 

 figure by which this account is illustrated (pi. 212), shows the dorsal 

 fin more advanced towards the head than we have ever seen in a 

 British Salmonoid.
