Pectoral short, scarcely falcate, its length contained twice in that 

 of the head. Yentrals slightly shorter than the pectorals. 



Scales small and cycloid. Head, with exception of cheeks and 

 postorbital region, naked. Scales on cheeks in about 7 or 8 

 series. Scales on nape and ante-dorsal region, smaller than those 

 of the rest of the body. 



Lateral line well-developed, continuous, forming a low, broad 

 keel on the j osterior part of the caudal peduncle. 



Color when fresh : Above, deep bluish-black; below, yellowish- 

 silvery. Two conspicuous blue lines along each side of 1 ody; the 

 upper narrow, passing from the upper edge of the orbit in an 

 almost direct line to the upper part of the caudal peduncle ; the 

 lower broader than the upper, beginning from the anterior edge 

 of the maxilla, passing under the eye across the opercle and 

 above the pectoral fin in an irregular line towards the caudal fin*.

*Possibly this had reached the tail in life, but on the posterior portion 

 of the body it was very indistinct and faded in my specimen.
