Young. Head above and back silvery greyish green, lighter on the 

 sides above the lateral line ; cheeks, opercles and beneath the lateral 

 line shining silvery ; from the vertex, between the eyes, a blackish 

 band obliquely backwards over the temple, terminating on the opercle 

 in a large steel-blue spot ; behind the occiput a broader black band 

 obliquely downwards to the origin of the lateral line ; membrane of the 

 dorsal spines blackish, minutely dotted with brown ; of the rays the 

 upper half minutely dotted with brown and black, the lower transpa- 

 rent ; the rest of the fins pale orange. 



Adult. Body paler ; in certain lights reflecting fifteen obliquely 

 backwards ascending lines ; no trace of the blackish band of the tem- 

 ples, and but a faint of the occipital ; a pale steel-blue spot on the

Total length : 6 inch. 



The length of the head is A\ in the total ; the depth at occiput \ 

 less than the length. The oblique diameter of the eye is \ of the 

 length of the head, equalling the distance of the eye from the muzzle. 

 The vertical diameter in front of the dorsal fin is J of the length of 

 the body, the caudal not included, but with the latter fin it is 3f in the 

 total length. The teeth of the external series of the upper jaw, are 

 but little longer than the rest, and rather closely set. The cirrus is 

 thick, fleshy ; in the adult fish its length equals the lower jaw to the 

 angle of the mouth, but it is shorter in the young. On each side of 

 and a little behind the cirrus appear two large pores. The fold of the 

 skin covering the infraorbitals and the upper maxillary forms a small 

 rounded lobe on each side of the muzzle. The vertical distance from 

 the lower part of the orbit down the fold is f of the oblique diameter 

 of the eye. The lateral line consisting of a small central tube on each
