a transverse series of teeth across its base ; body of the vomer with 

 a double series of strong teeth, the teeth being placed either oppo- 

 site to each othe? or alternately ; this seiies of teeth is persistent 

 throughout life. Fins comparatively short and rounded : the length 

 )f the pectoral is one-half, or rather less than one-half, of the distance 

 of its base from that of the ^■entral ; in specimens under 10 inches 

 it is somewhat longer. The caudal fin is emarginate in young ex- 

 amples, but has become truncate in specimens of eight inches in 

 length, in which the length of the middle caudal raj^s is only two- 

 thirds of that of the outer ones. The hind part of the body is short 

 and rather high ; there are about sixteen scales in a transverse 

 series descending from behind the adipose fin obliquely backwards to 

 the lateral line. 



Body, head and dorsal fin generally with numerous red and black 

 spots ; a part of the latter have generally a light edge ; these black 

 spots are either round or more irregular in shape, composed of 

 X-shaped marks. Anterior margin of the dorsal and anal, and the 

 outer one of the ventrals, generally yellowish. 



A non-migratory species, inhabiting numerous fresh waters of 

 Central Europe, Sweden and England ; rivers of the Maritime Alps.
