Largest specimen observed, 2i mcties; female mature at a length 

 of inches. 



Head weU proportioned in its shape, and ratlier small when com- 

 pared with the body; body much less stout than in S. fario. The 

 posterior point of junction of operculum and suboperculum is nearer 

 to the lower anterior angle of the suboperculum than to the uppei 

 end of the gill-opening. Pra;operculum generally with a very in- 

 distinct lower limb. Snout of moderate length, conical, not much 

 produced in the male sex, in which a mandibular hook has never 

 been observed. Maxillary much longer than the snout, but much 

 narrower and more feeble than in S. fario (see p. 6) ; in specimens 

 13 inches long it extends to below the hinder margin of the orbit, 

 and at no age does it reach much beyond it. Teeth moderately 

 strong ; the head of the vomer is triangular, a little broader than long, 

 with a transverse series of two or three teeth across its base ; the teeth 

 of the body of the vomer form a single series, and are persistent 

 throughout life. Fins well developed, not rounded ; the pectoral is 

 pointed, and in specimens of more than 12 inches in length its length 

 is less than one-half of the distance between its base and that of the 

 ventral. The caudal fin always has the lobes pointed, is emarginate, 

 and appears truncate only when stretched to the utmost extent. In 

 specimens 13 inches long the middle caudal rays are not quite half 

 as long as the outer ones, and in older ones they are half as long. 

 The hind part of the body is rather slender. There are from thirteen 

 to fourteen scales in a transverse series descending from behind the 

 adipose fin forwards to the lateral line. 



Upper parts brownish or greenish olive ; sides of the head with 

 round black spots ; sides of the body with more or less numerous X- 

 shaped, sometimes rounded brown spots. Dorsal and adipose fins 

 with numerous small brown spots ; extremity of pectoral light 

 blackish ; dorsal and anal without black or yellow margin. 



A nonmigratory species, inhabiting Loch Leven and other lakes of 

 southern Scotland and of the north of England.
