Similar to S.p>urpuratus, but with considerably smaller scales The 

 posterior point of junction of operculum and suboperculiim is midway 

 between the upper end of the gilLopcning and the lower anterior 

 angle ot the suboperciUum. Prneopcrculum broad, with the lower 

 hmb very indistinct. Snout of moderate extent ; maxUIary narrow 

 and feeble, extending to the vertical from the hind maroin of the 

 orbit in specimens 7 inches long, and beyond it in older ones. Den- 

 tition moderately developed; vomerine teeth in a zigzag series rarely 

 placed m a pair. Caudal fin emarginate in young specime'ns, the 

 imdcUe rays being half as long as the outer ones, and truncate in 

 adult ones. There are fifteen or sixteen scales in a series obliquely 

 descending from behind the adipose fin to the lateral line Heacl 

 and body, dorsal and caudal fins covered with black specks

We have examined the tyiDical specimen of this species ; it is the 

 «kin of an adult male fish. As far as we can judge from this spe- 

 cimen, this species IS yeiy closely allied to S. cambrlcus: we cannot 

 fand any external distinctive characters ; and if the two fish do not 

 ^^''^^'''J internal characters, we doubt not that they are spe- 

 c^caUy the same^ According to PaUas this migratory Trout wo dd 

 ascend from the Bay of Penjinsk into the river Worofskaia. 



Valenciennes has identified this species with S. >-o.s//. Richards. • 

 having the typica specimens of both fishes before us, we find that 

 they are specifically, if not genericallv, quite distinct
