Depth, of body 2|- to 31 in the length, length of head 3 to 3|. 

 Snout I to I diameter of eye, which is 2|- to 3^ in length of 

 head ; interorbital width 3 to 3|. Maxillary extending to below 

 anterior -1- of eye. 16 to 18 gill-rakers on lower part of anterior 

 arch. 40 to 45 scales in lateral line, 4 or 4| from sheath at base 

 of spinous dorsal to highest part of lateral line, 8 or 9 thence to 

 base of pelvic fin. Dorsal X 10-12; fifth spine usually longest, 

 g to |- length of head ; last as long as sixth, seventh, or eighth, 

 -^ to more than f length of head. Anal III 11-13 ; third spine 

 shorter than tenth dorsal ; base nearly as long as head, nearly 

 twice as long as caudal peduncle. Pectoral |- to -I length, of 

 head. Caudal moderately emarginate, the middle rays | to |- 

 as long as longest. Caudal peduncle longer than deep. Silvery, 

 usually dark spotted above lateral line and sometimes below it ; 

 soft dorsal and anal dark edged, at least anteriorly, often dark

Numerous examples, 75 to 160 mm. in total length, including 

 the types of I), leuciscus, kindly lent tome by Mr. L. Doncaster. 

 Some examples are almost covered with spots, others are 

 silvery with scarcely a trace of spots, the variation in this respect 

 recalling our British Trout ; probably the silvery examples are 

 marine, whilst the strongly spotted ones may have been for a 

 long time in fresh water.
