one-half of the second ; the sixth is the longest, 3| in the length of 

 the head ; the twelfth longer than the eleventh. The soft portion of 

 the dorsal is more elevated and rounded ; the distance between the 

 dorsal and caudal fins is less than the height of the tail below the 

 end of the dorsal. The caudal is rather short, truncated, and has 

 the angles rounded. The origin of the aiial falls somewhat behind 

 the vertical from the origin of the soft dorsal, whilst the ends of both 

 correspond to each other; the spines are? moderately strong; the 

 first is one-half of the second, which is stronger, but not longer than 

 the third ; the soft portion is lower than the corresponding dorsal 

 fin. The pectorals are rounded, verj- short, and 8| in the total 

 length. The ventrals are inserted immediately behind the pectorals, 

 and rather longer, their length being one-seventh of the total. 



The scales are of moderate size, minutely ciliated ; those of the 

 belly are very small. The lateral line is nearly straight, slightly 

 bent downwards beneath the soft dorsal. 



The teeth form villiform bands, with an outer series of stronger 

 ones ; there are no teeth on the palate. 



The fishes are now uniform greyish, silvery shining ; each scale 

 has the margin darker.
