interior ridge of the bone. The ojjerciiliim is quadrangular, with a 

 slight exterior ridge ; the interopcrcidum rather broader than the 

 suboperculiuu. The anterior portion of the frontal bones is slightly 

 convex, porous. The occipital crest is strong, and extends on the 

 frontal bones to above the centre of the orbit ; the lateral crests also 

 are veiy developed. The basal portion of the brain-capside is 

 shghtly compressed, and the basisphenoid has a quadi'angular open- 

 ing before the occipital joint. The humeral arch and the pubic 

 bones do not show any peculiarity. 



There are ten abdominal and fourteen caudal vertebrce, the length 

 of the former portion of the vertebral column being to that of the 

 latter as 1 : 1"4. Some of the anterior ribs are broad in their basal 

 portion. The neural and haemal spines slender, the interneurals di- 

 lated ; the first interhaimal is rather feeble, but it has a very distinct 

 anterior ridge.

The height of the body equals the length of the head, and is 3| in 

 tlie total. The snout exceeds in length the diameter of the eye. 

 Canines veiy strong. The praeorbital scaleless, nearly as high as the 

 eye ; there are eight or nine rows of scales between the praeorbital 

 and the margin of the praeoperculum, which is also covered with 

 scales for its greater part ; the scales above the lateral line scarcely 

 smaller than those of the sides. The spines of the fins slender, 

 rather flexible ; the foiu'th of the dorsal longest, and not quite one- 

 third of the length of the head ; the second and third anal spines 

 nearly equal. Caudalis emarginate. Red, with silvery longitudinal 

 bands.

The height of the body is 3^ in the total length, the length of the 

 head fom- times ; the diameter of the eye is 2| in the length of the 

 snout, and 6f in that of the head. Canines very strong. The prae- 

 orbital regularly quadi'angadar, scaleless, much higher than wide ; 

 the width of the orbit is 2| in the height of the praeorbital. There
