Height 6.58.7, 8 10 in length with caudal. Head 33.5, 

 3.6 3.9 in length with caudal. Eye 5.4 (spec, of 200 mm. 

 length) 8.5 (spec, of 920 mm. length), 2.4 3.5 (in spec, of 

 920 mm.) in snout, somewhat more or less than interorbital 

 space, but in large specimens 1.8 in that space, 1.8 (spec, of 

 200 mm.) 5.7 (spec, of 920 mm.) in postorbital part of head. 

 Maxillary reaching nearly to vertical through frontborder of 

 eye, 2.1 2.4 in head. Angle of praeoperculum rounded. Oper- 

 culum with two flat flexible spines at the superior part of its 

 hindborder. A single series of compressed teeth and two 

 distant strong canines in the upper jaw. In the lower jaw 

 similar compressed teeth, which are directed backwards, smaller 

 and close together in the anterior part, more distant and cani- 

 noid in the posterior part. Besides this a single strong canine 

 at symphysis, bent backwards and fitting into an opening at 

 the tip of the snout. Four to eight compressed canines of 

 different length in a series on each palatine. Mandibles with 

 a fleshy symphysial knob. Origin of first dorsal above tip of 

 pectorals and somewhat behind origin of ventrals. Its three 

 first spines subequal, shorter than postorbital part of head. 

 Base of second dorsal more than twice in its distance from 

 last spine of first dorsal. Second dorsal and anal concave, the 

 rays decreasing in length posteriorly but the last ray besides 

 prolonged. Origin of anal below first half of second dorsal. 

 Pectorals somewhat pointed, about equal to postorbital part of 

 head. Ventrals truncate, shorter than pectorals. Caudal forked, 

 in a large specimen (see figure) the middle caudal rays are 

 somewhat produced, through which this fin is trilobed. Colour 

 of alcohol specimens brownish or grayish above, silvery below, 

 the brown of the back connected with a number of crossbars 

 on the sides of the same colour as the back, which intersect 

 the lateral line and are obsolete in large specimens. Fins more 

 or less dusky or blackish, the ventrals excepted, which are 

 yellowish. Length 1500 mm.
