 sea, and are the ^/7i ch¿vtodon, th^ cock -fish, and the 

 tollo. The gilt chœtodon (chaetodon aurens) is flat, 

 of an oval form, about a foot in length, and covered 

 with very small scales. It is of a bright gold co- 

 lour, and marked v^^ith five distinct bands, of more

 which is longer than the fin, is the only bony part of
