The form of the fish is much like that of ^. deliciosus, being, perhaps, 

 somewhat slenderer. Head in length, 4 ; dejith, 5. Head somewhat 

 like that of deliciosus. Mouth like this species, but smaller, the 

 maxillary not reaching back to a perpendicular from the front of the 

 orbit. Head, viewed from the side, somewhat more pointed than that 

 of deliciosus, the snout not being so heavy. The antorbital bone dis- 

 tinctly larger and projecting further toward the tip of the snout than 

 that of deliciosus. Eye greater in diameter than the length of the 

 snout 5 contained in the head 3;^; the snout in the head 4;^. Teeth 

 4-4, with distinct masticatory surface ; the first tooth hooked. 



D. I, 8 ; A. I, 9, the ninth ray dividing at its base into two subor- 

 dinate rays. Insertion of the dorsal directly over the ventrals. Pectorals 

 falling short of the ventrals ; the latter extending to the vent. Caudal 

 peduncle longer and slenderer than in deliciosus. 



Scales 5-35 or 30-4; 15 between the occiput and the first dorsal ray. 



The color is quite dark above, all the scales having broad dusky 

 edges. The sides are silvery, but through the silvery band there runs 

 from the snout to the caudal base a distinct dusky streak. This strealv 

 is very distinct on the snout and opercle. Along the sides the streak 

 is rather leaden in hue, but the pores of the lateral line are distinctly 

 marked by black dots. Top of the head dusky. Belly, lower jaw, and 

 throat pale. Cheeks and opercle silvery. A narrow black line along 

 the lower edge of the caudal peduncle. 



Dorsal, caudal, anal, and front edge of the pectoral fins dusky, with 

 black puuctulations ; the ventrals pale. 



Total length of the specimen a little over 2 J inches.
