lengths beyond the mouth before it fades out. In No. 25559 some of 

 the scales on the back are conspicuously black-edged. In No. 25560 

 (now U.S.N.M. No. 77083) the posterior half of every second or third 

 scale in the seventh longitudinal series is black, and the scales between 

 are somewhat darkened at the tips and lighter at their bases ; this ar- 

 rangement persists on the anterior third of the body with fair regu- 

 larity. The ventral coloration of No. 25559 is like that of the type. 

 In the other example, however, the dark blotches occur usually on the 

 bases of the scales of the first longitudinal series and only rarely on the 

 ends of the ventrals.

In U.S.N.M. No. 80829, from Palma, the light lateral stripe is 

 exceedingly conspicuous on the four outer scale rows, while on the 

 fifth scale row a diagonal black spot across the upper posterior border 

 of each scale emphasizes the separation of the lateral and dorsal 

 colors. U.S.N.M. No. 80828 from La Grande Source has the lateral 

 light stripe apparent on the anterior part of the body, but posteriorly 

 it becomes indistinct, since the black borders of the fifth row of scales 

 are much less accentuated. Three others from Anse a Galets do not 

 enlarge the known scale counts of this species. U.S.N.M. No. 80829 

 has a head and body length of 797 mm.; tail, 544 mm. + tip.
