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

 The posterior point of junction of operculum and subopercidum is 

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

 anterior angle of the suboperculum. Prseoperculum with the lower 

 limb very indistinct, subcrescentic. 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 solid, 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 series, persistent through life. Fins moderately 

 developed ; the caudal fin is very slightly emarginate in specimens 

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

 thirteen or fourteen scales in a transverse series descending from 

 behind the adipose fin forwards to the lateral line. 



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

 on the belly; body with very 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, 



a. Forty inches long: skin. River Narenta. Presented by L. 



Conyngham, Esq. 



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



L. Conyngham, Esq. 

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

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

 important differences. Perhaps no other European Salmonoid has 

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

 the large intermaxillary teeth, from which the name " dentex " w-as 

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