54 SAIMONID^. 



The length of the pectoral fin slightly exceeds that of the space 

 between the orbit and the angle of the operculum. "Ventral shorter 

 than pectoral, a little more than half the length of the distance of 

 its root from the vent ; its outennost ray is vertically opposite the 

 eleventh of the dorsal fin. Caudal ray emarginate. 



There are 120 transverse series of scales counting immediately 

 above the lateral line ; the series descending from the first dorsal 

 ray backwards to the lateral line contains twenty-eight scales ; that 

 from the adipose forward to the lateral Mne contains sixteen scales, 

 and there are twenty-four longitudinal series between the lateral line 

 and the root of the ventral. All the scales are rounded behind. 



Back greenish brown ; sides reddish, shining silvery ; belly silvery ; 

 numerous X-shaped black spots are scattered on the regions above 

 the lateral line ; the operculum bears two or three dark-brovm spots ; 

 the dorsal has two or three series of black spots ; the other fins im- 

 maculate ; the pectoral white, with the outermost ray black along its 

 outer margin, and the extremity of the fin broadly tinged with 

 blackish ; caudal and anal blackish.

The greatest depth of the body is below the origin of the dorsal 

 fin, and is a little more than one-fifth of the total length (caudal not 

 included) ; the length of the head is contained about four times and 

 a half in the same. The snout is scarcely produced, conical, and is
