Total length : 6 inch. 



The length of the head is J of the body, the caudal fin not included ; 

 the height at occiput f of the length. The eye occupies the second 

 fourth of the head ; the diameter of the orbit is ^ of the length of the 

 head ; the distance between the eyes across the forehead is \\ diameter. 

 The infraorbital is triangular, covered with small scales, and with three 

 pores placed obliquely in the middle of the external surface ; the ante- 

 rior margin is finely toothed, and slightly arched, but becomes a little 

 concave towards the truncated, finely -toothed apex. The superior 

 margin is somewhat angular in the centre, on each side of which appear 

 the openings of the nostrils. The mouth is small, transversal ; the 

 angle is situated opposite the posterior opening of the nostril ; the lower 

 jaw is but slightly shorter than the upper. There are no visible teeth 

 in the lips ; the lower has in the centre a strong tubercle which in 

 front and beneath is deeply furrowed. On each side of the vomer 

 appears a strong transversal ridge. Under each branch of the lower 

 jaw appear three pores. The preopercle is covered with large very 

 thin scales, and has a long transversal incision in the posterior margin, 

 near the angle ; the opercle and subopercle are aparently without 

 scales, and brilliantly shining with silver. Nearly all the scales of the 

 occiput are divided lengthwise by a shallow furrow, which on the 

 scales of the body becomes a short longitudinal line. But the 

 scales immediately below the pectoral fin are each marked near the 

 root by a short vertical line. A longitudinal series between the gill- 

 opening and the root of the caudal consists of 39 scales ; an oblique in 

 front of the anterior dorsal fin of 14. The vertical diameter in the latter 

 place is A\ of the total length. The length of the three anterior dorsal 

 spines is about \ of the length of the head, and equals the extent of 

 the fin itself ; the fourth spine slightly exceeds \ of the length of the 

 preceding three. At the base appears an elongated scale, extending to 

 the posterior margin of the fin. The second dorsal spine is situated in 

 the centre between the muzzle and the root of the caudal fin. The pos-
