Color. — The upper part of the body is of a pale 

 brown, mottled with darker undulating, reticulated 

 markings ; the sides lighter, with a great number of 

 circular yellow spots, varying in their size from a small 

 point to a line or more in diameter, and many of them 

 having in the centre a bright red spot ; sometimes, the 

 yellow color surrounding them having partially disap- 

 peared, they seem distinct from the circular spots, or 

 are surrounded by a dull bluish halo ; these red spots 

 differ exceedingly in number in different specimens, 

 in some three or four only are observable, and those are 

 situated below the lateral line ; in others, twenty or 

 more are seen, scattered above and below the lateral 

 line indiscriminately, presenting a beautiful appear- 

 ance. The body beneath is white, yellowish-white, 

 slightly or dark fuliginous. Head above darker than 

 the back of the fish. Gill-covers golden, and fuligi- 

 nous. The dorsal fin is yellow with irregular trans- 

 verse black bands. The first ray of the pectorals and 

 ventrals is white, the second dark-colored, the remain- 

 der of the fin is red. The first ray of the anal fin is 

 white, the remainder generally red. The caudal fin is 

 of a dirty reddish -brown, mottled with black spots.
