The caudal is very slightly emarginate, and has the lobes pointed. 



There are 121 transverse rows of scales, counted immediately 

 above the lateral line ; the series descending obliquely backwards 

 from the origin of the dorsal fin to the lateial line has 30 scales ; 

 that from the hinder end of the adipose to the lateral line has 16 

 scales ; there are 22 longitudinal series between the lateral line 

 and the ventral fin. All the scales are rounded and without median 

 ridge. 



Greenish brown, each scale with a silvery centre, which is smallest 

 in the scales on the back, and largest in those on the side ; belly 

 with a greyish hue ; a few rounded, reticulated black spots on the 

 sides, and a series of red ones along the lateral line. Operculum 

 with a large silvery blotch. AU the fins dark-coloured ; the dorsal 

 with rounded black spots of moderate size.

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

 fin, nearly equal to the length of the head, and contained four times 

 and one-third in the total length (without caudal) . 



The snout is rather short and obtuse, its length is equal to that of 

 the diameter of the eye, and rather less than half of that of the post- 

 orbital portion of the head ; the length of the maxillary bone is 

 equal to that of the snout together with the diameter of the eye ; its
