Head of moderate size when compared with the body, rather low. 

 The posterior point of junction of operculum and suboperculum is 

 midway between the upper end of the gill-opening and the lower 

 anterior angle of the suboi)erculum. Pra^operculum with the lower 

 limb very indistinct, subcresceutic. Snout more or less produced, 

 according to age and sex. Maxillary as broad and strong as in 

 S.fario; in old individuals it is extremely strong and soUd, and 

 bent downwards ; it extends to below the hind margin of the orbit 

 in specimens 12 inches long, and much beyond it in old ones. Teeth 

 strong, especially those of the intermaxillary ; vomerine teeth in a 

 double longitudinal seiies, persistent through life. Fins moderately 

 developed ; the caudal tin is very slightly emarginate in specimens 

 12 inches long, and becomes convex in old examples. There are 

 thii-teen or fourteen scales in a transverse series descending from 

 behind the adipose tin forwards to the lateral line. 



Brownish (darker or lighter), silvery towards the sides, and brown 

 on the belly ; body with veiy numerous and very small irregular 

 black dots ; head with numerous round spots and undulated mark- 

 ings ; red spots are intermixed between the black ones. Base of the 

 dorsal with black spots. 



A non-migratory species from the rivers of Dalmatia.

b. Forty-four inches long : stuffed. River Narenta. Presented by

This species appears to be nearly allied to S. lemamts and to 

 S. ferox, unless a more detailed examination reveals other more 

 important differences. Perhaps no other Eiu'opean Salmonoid has 

 the jaws so powerfully developed as this species ; the character of 

 the large intermaxillaiy teeth, from which the name " dentex " was 

 derived, is not so prominent in old age as in young.
