Total length : 5 ft. 



The general form resembles that of C. talabon, but it is less slender, 

 the muzzle less elongated, the eye larger, the teeth of the vomer and some 

 of those of the lower jaw are tricuspidate ; the dorsal and anal extend 

 farther forwards ; the pectorals and caudal are shorter, and the bran- 

 chiostegous rays more numerous. The length of the head, from the 

 muzzle to the gill-opening, is contained from 6^ to 6^ times in the total 

 length. The distance from the muzzle to the anterior orbital margin is 

 £ of the length of the head. The distance across the notch of the upper 

 jaw equals the horizontal diameter of the eye, which is \ of the length of 

 the muzzle ; the distance between the anterior margins of the orbits is 

 1^, between the posterior margins it is two diameters. The eye 

 occupies the third-eighth of the head; the anterior margin of the 

 orbit is situated at the posterior third of the distance from the muzzle 

 to the angle of the mouth ; the length of the mouth is contained 2\ to 2\ 

 times in that of the head. The anterior, tubular, aperture of the nostril 

 opens at the end of the anterior third of the distance between the muzzle 

 and the eye ; the posterior occupies the commencement of the posterior 

 third of that distance. The pores of the crown of the head are very 

 indistinct. The general distribution of the teeth resembles that of C. 

 talabon, but the teeth themselves present the following differences. 

 Those of the mesial line of the vomer are compressed, with trenchant 

 edges and tricuspidate ; the central cusp is much larger than that at
