Teeth in upper jaw begin far behind snout, in three series, 

 the outer one of minute teeth closely appressed against the much 

 larger second row; inner row short, curved, and separated 

 from outer row for most of its length by a wide interspace; 

 intermaxillary plate with about six or eight canines around 

 margin and a short row of smaller teeth in center; vomer with 

 a central row of about eight or ten strong, sharp-pointed canines, 

 without basal lobes, the posterior ones largest and roughened 

 as if they might develop lobes, and two lateral rows of very 

 small, irregular, and poorly developed teeth very close to the 

 central row; teeth in mandibles in three rows, those of outer 

 row small, closely set behind but apart, pointed, and turned 

 more or less outward in first half of jaw; second row of very 

 much larger and stronger, laterally compressed teeth, ending at 

 front in four or five long, strong canines; inner row of minute 

 teeth. 



The general arrangement of the teeth is like that in Weber 

 and Beaufort's figure, which does not agree with their text. 

 The large teeth are subject to considerable variation, as in my 

 specimens I can see that teeth have been broken out in some 

 places and in others are only partly regrown. 



The dorsal is very low in front and begins in advance of the 

 gill opening; on the tail it is half or more than half as high as 

 the body beneath; the anal is very low. 



Trunk plump, rounded, becoming compressed on tail, which 

 is greatly flattened posteriorly; snout sharp, very long and 

 narrow. 



Ashen gray to olive above, becoming darker on snout, paler 

 on sides, and merging into white on belly, everywhere with 

 a silvery sheen ; belly and lower part of sides sprinkled thickly 

 with dark dots; jaws and sides of trunk with a butter-yellow 

 or golden tinge which extends over pectorals, these more or 

 less dusky on inside; dorsal pale, with a yellowish cast, anal 

 silvery whitish, each with a broad black margin; lateral line 

 conspicuous, its origin below nape. 



The larger of the two specimens cited above had a broad 

 yellow-green band on the upper surface along the base of the 

 dorsal ; the sides were silvery with a golden luster on the head 

 and body, this fading soon after death; the underside paler, 

 becoming white on the throat and belly; the pectoral was pale 

 lemon yellow, with a dusky blotch more or less evident on the 

 inner side near the extremity.
