three times and a third in the length without the caudal; the height of the body 

 is about one-sixth of the total length ; the diameter of the eye is one-third of the 

 length of the head ; and the width of the interorbital space is two-thirds of the 

 diameter of the eye. 



There are three or four rather strong canines on each side of the upper jaw. 



The posterior margin of the prseoperculum is finely and evenly serrated ; the oper- 

 culum terminates in a short spine. 



The second spine of the anal is stronger but shorter than the third, which is shorter 

 than the first ray. Both dorsal and anal fins can be received within a scaly sheath. 

 The caudal is deeply forked ; the lobes pointed, the upper being produced into a 

 filament. 



The upper part of the body is pale violet ; from the posterior margin of the eye to 

 the base of the caudal there is a very faint violet longitudinal band ; below this the 

 colour is bright yellow, the lower part of the belly being silvery. Ventrals yellow at the 

 base. Dorsal with a narrow yellow marginal line. (Steindachner.)
