genus is the fish calledThe Piper, of a red colour, 
and celebrated for its excellency as an article of 
food. But the most remarkable species is the 
Flying Gurnard, which is of a reddish colour, with 
very strong scales, and the pectoral fins so very 
large as to represent a kind of wings, and to 
enable the animal to use them occasionally in the 
manner of the flying-Fishes emphatically so called : 
these broad pectoral fins are also remarkable for 
the beauty of their colour, being of a fine oblive 
. green, with numerous sapphire-coloured spots. 
The last Linna^an division consists of the Ab- 
dominal Fisiiea, or those in which the ventral fins 
are placed beyond the pectoral ones. This order 
contains many very curious and interesting genera, 
of which, however, I shall only particularize a very 
few, as clear exemplifications of the order. Of 
these one of the most important is the genus 
Salmo, comprising all the Salmon and Trout race: 
a numerous tribe, distinguished by having a 
smooth and somewhat lengthened body, with the 
hind part furnished above with a small fatty fin 
without any rays. The tongue is cartilaginous, 
and often beset with teeth as well as the jaws.
