 second series of still narrower ones which are alternate with those 

 of the front series. The -width of the praeorbital, above the angle of 

 the mouth, is less than one-half of that of the orbit. Caudal fin 

 forked. Green, each scale with a bluish transverse streak ; a large

The height of the body is two-fifths of the total length (the caudal 

 fin not included) ; the width of the orbit is more than that of the 

 interorbital space or than the length of the snout ; the greatest width 

 of the prajorbital is one-third of the diameter of the eye. Teeth 

 very narrow. Caudal subtruncated, with the lobes rounded. Blue, 

 each scale with a yellow spot ; a dark band along the middle of the 

 nape and of the forehead ; another from the origin of the lateral line 

 through the eye to the snout, where it meets that of the other side. 

 The lower side of the head brownish. The lower half of the dorsal 

 fin dark-vioxet, the upper transparent, with a black margin along the 

 spinous portion. A round blade spot posteriorly in the aanl of the

The height of the body is contained twice and a fourth or twice 

 and a half in the total length (the caudal fin not included). The 

 width of the orbit is more than that of the interorbital space or than 

 the length of the snout. The greatest width of the praeorbital is 

 nearly one-half of that of the orbit. Teeth very narrow. Caudal 

 slightly rounded. Blue, each scale with a yellow spot ; a dark band
