Body fusiform, subterete, moderately elongate, its greatest 

 depth two ninths of total length to base of caudal fin; least 

 depth of caudal peduncle two thirds of the short diameter of 

 the eye, its width more than one half the length of head and 

 equal to snout and eye combined; head conical, pointed, com- 

 pressed, its length contained three and three fourths times in 

 total to base of caudal, its width equal to one half its length, 

 width of interorbital space three fifths of length of postorbital 

 part of head; snout long, pointed, two sevenths as long as the 

 head; lower jaw slightly projecting, the mandible extending to 

 below hind edge of pupil, its length less than one half the 

 length of head; the maxilla reaching nearly to front of pupil. 

 The eye is large, covered in front and behind by an adipose mem- 

 brane, its length three elevenths of length of head or two thirds 

 of length of postorbital part of head. The spinous dorsal origi- 

 nates over the middle of the pectoral, a little behind the inser- 

 tion of the ventral; the base is as long as the head without the 

 snout and is much longer than the mandible; the second spine 

 longest, one half as long as the head, the last spine minute, 

 about one fifth as long as the eye. The interspace between the 

 dorsals is only two thirds of depth of bod3^. The second dorsal 

 base is chiefly opposite anal base, but more in advance than in 

 Scomber scombrus, its length equal to postorbital part 

 of head; the longest ray is one fourth as long as the head, the 

 last ray one half as long as the eye; the second dorsal is fol- 

 lowed by five finlets, which increase in size posteriorly, the last 

 one larger than last ray of dorsal, and two thirds as long as the 

 eye. The anal origin is under the fifth or sixth ray of the 

 second dorsal; the base of the fin is as long as the postorbital 

 part of the head; the longest ray equals the longest of the dor- 

 sal; the last ray is one half as long as the eye; the fin vis fol- 

 lowed by five finlets of the same "size as the dorsal finlets and
