Body fusiform, much tapered at both ends, moderately elon- 

 gate, robust, its greatest hight nearly equal to length of head 

 and nearly one fourth of total length without caudal, its great- 

 est width two thirds of its hight; least depth of caudal peduncle 

 one third of length of snout; head four fifteenths to one fourth of 

 total length to caudal base, its width over the opercles equal 

 to length of its postorbital part; interorbital space strongly 

 convex, one third of length of head, greater than snout, twice 

 diameter of orbit; snout rather long, one third as long as the 

 head, acute, the jaws equal in front; maxilla much expanded 

 behind, reaching slightly behind orbit, the upper jaw one half 

 the length of head; mandible equal to width of body, reaching 

 considerably behind eve; eve small, vertically oblong, its verti- 

 cal diameter about one half the length of snout. The spinous 

 dorsal begins directly over the insertion of pectoral; the fin is 

 very long, high in front, tax>ering rapidly and almost regularly 

 to the last spine, which is only about one sixth as long as the 

 second, and longest, this being two fifths as long as the head. 

 The interspace between the dorsals is one half as long as the 

 eye. The second dorsal base is as long as the snout and eye 

 combined; the longest ray is four times as long as the last ray 

 and one third as long as the head; the upper margin of the fin is 

 deeply concave; the fin is followed by eight small finlets, the 

 longesit as long as the eye. The anal origin is under the last 

 dorsal ray or the first dorsal finlet; the base of the fin is as 

 long as the snout; the longest ray is nearly five times as long 

 as the last ray and three eighths as long as the head; the fin is 

 followed by seven or eight finlets (usually seven) the long- 

 est equal to length of eye; the anal is deeply concave, 

 like the second dorsal. The caudal fin is crescentic, the 

 external rays three times as long as the middle rays and 

 the lobes narrow and tapering, their width at base about 

 one third of their length and one fourth the length of 

 head. The ventral origin is under the second or third spine 

 of the dorsal; the fin is three tenths as long as the head; its 

 sheath is small and raylike, less than one half as long as the 

 fin. The pectoral is falcate, broad at base, short, reaching to
