scarcely oxceoding- half the diameter of the eye; nostrils only sepa- 

 rated b}^ a thin lobe which covers the posterior oritice, openinj»- upon 

 the lower sides of the snout midway between the intermaxillary and the 

 eye; interorbital space considerably more than tiie diameter of the eye. 

 The edge of the opercle forms a somewhat obtuse and rounded angle. 

 Upper part of the head rounded upon the sides; its upper protile 

 straight until the snout, which is somewhat convex. Line of demar- 

 cation between head and neck nearly straight: the skin of head and 

 opercles smooth. 



Scales with their surfaces marked with tine striiv. \erv compact and 

 somewhat divergent. 



Insertion of dorsals slightly before the ventrals and nearer the head, 

 the second and third rudimentary rays like the first and second of the 

 anal, but the size of the tins a third larger than the latter; margin of 

 anal straight, equals, or somewhat more than ventrals, and preceded 

 by a weak spine less than half the length of the shMider and flexi])ie 

 rav which follows, and which is also longer than the first divided ray 

 of the tin; caudal emarginate, lobes pointed, and their length about 

 half the fin; pectorals equal to head without snout and not i-eaching 

 to l)ase of ventrals ])y a space equal to half their own length; ventrals 

 a tifth shorter than pectorals and almost reach the anus. Anus entirely 

 after the origin of the anal and a])out two-thirds of the distance 

 between tip of snout and base of caudal. 



Color in spirits brown above with silvery reflections, below pale; 

 opercles pure silvery w^hite and the tins uniform yellowish; scales 

 sprinkled with numerous minute black dots; a broad and ill-detined 

 l)and of bluish-silvery extending along the sides of the body.

Form elongate; depth 5i in the length of the body between tip of

 Head longer; eyes much larger; snout bulky and convex aV)ove; 

 mouth cleft horizontal. Su])orbitals narrower; l)ar])els somewhat 

 longer; pectorals very long and reaching nearly to the ba.se of the 

 ventrals; lateral line .slightly decurved; anus remote from the anal fin;
