Description of the specimen. — This fish is much more elongate than 

 most of the species of this genus, and resembles Hoi. lamarchii, the 

 height of the body being 2 j in the total leng-th, without caudal, and 

 3-1- if that fin is included. The upper and lower profiles converge 

 anteriorly in the same curve. The snout is very short, and equals in 

 length the diameter of the eye, or the distance between the eyes. 

 The prfeorbital has some very fine denticulations infeiiorly. The 

 posterior margin of the prteoperculum is finely serrated, the lower 

 has some teeth pointing backwards ; the spine is flat, smooth, and 

 reaches to the base of the pectoral. The dorsal fin begins in the 

 vertical from the base of the ventral, and has rather feeble spines : 

 the first is the shortest ; the following increase very slightly in length 

 to the last two, which are the longest and two-thirds the length of 

 the head : the posterior upper angle of the fin is formed by the 

 eighth and ninth rays, which are the longest. The caudal is forked, 

 both the lobes being produced. The anal begins in the vertical from 

 the twelfth dorsal spine, with three rather feeble spines, the poste- 

 rior of which is the longest ; the soft portion is longer and higher 

 than the corresponding part of the opposite fin. The ventral reaches 

 to, the pectoral nearly to the vent.
