174 Dr. Richardson's Contributions to 



lateral line curves like the back, but nears it slightly in its progress, 

 and changes suddenly to a straight course through the tail. It is 

 formed by a series of simple linear elevations which become conti- 

 nuous towards the tail ; two or three next the shoulder emit ob- 

 lique folds upwards. All the scales are small and firmly imbedded 

 in the integument. 



The colours of the specimen are faded, but blackish dots are di- 

 stinctly seen on the sides. They coalesce into short curved lines 

 on the back, become smaller as they descend beyond the lateral 

 line, and disappear altogether above the level of the pectorals. There 

 are vestiges of dark shades on the spinous parts of the dorsal and 

 anal ; the rest of the fins appear to have been pale and spotless. A 

 pale band, of a pearly hue in the dried specimen, runs obliquely for- 

 wards and downwards from behind the eye, and includes the gill- 

 cover, preoperculum, and the scaly half of the cheek. Two or three 

 short bars run back from the preorbitar over the scaly part of the 

 cheek.
