LEPIBOPUS. 
Bodti’ elongated and eompressed; jaws projecting, armed with strong 
teeth; cleft of the mouth wide. Dorsal fin long, and with the anal 
fin separate from the tail, which is well marked. The ventral fins 
are represented only by a pair of moveable scales; from whence the 
name of the genus, which was formed by Dr. Gouan, professor of 
natural history at Montpellier, for the classification of a fish he had 
discovered, and which is the only species we know of this genus; unless 
it shall be determined, from the differences we have to point out, 
that Disso is correct in supposing that there are two to be regarded 
as positively distinct. According to Gouan, this fish is to be defined 
as having the body sword-shaped, of a silvery colour, with the head 
protruded, and furnished with three scales, two of which occupy the 
place of ventral fins, whilst the third takes the position of the anal. 
In the figure which he gives he represents the tail as lengthened into 
what is termed the lancet shape, in which he ditt'ers greatly from other 
observers, and from our own example especially; and it was on this 
account chiefly, although not solely, that Risso who supposed himself 
the discoverer of a second species of this genus, which answers more 
directly to the fish wo have to describe.
