dark brown, with small closely set specks of blue. All other 

 parts, including whole of tail, pure white. The blue speckling is 

 apparent on the white portions also when examined closely. This 

 phase is shown in the photographic plate opposite page 382 in 

 American Food and Game Fishes, but the tail is black. 



In another phase the white invades the upper dark third, leav- 

 ing about four dark blotches across back and dorsal, with irregu- 

 lar dark lines on head. 



In a common swimming color the entire body is dark reddish 

 brown, everywhere minutely speckled with intense blue. 



A fourth phase shows upper and lower thirds of the body dark, 

 the median third pure white. Blue dots indistinct. 



In a fifth phase (in the photographic tank) the fish becomes 

 a pale gray with the body dark blotched and the blue specks dis- 

 tinct. 



The coney presents still other aspects of coloration, but the 

 heavy blotches never appear except on a frightened fish, in the 

 photographic tank. 



HoGFiSH, {Lachiiolaimiis iiiaxiiiius). Three principal phases: 

 Dark brown phase: Uniform pale reddish brown, whole front 

 of head rich brown, a band of the same across base of the tail. A 

 narrow band of this color extends also along the back at base of 

 dorsal (fig. i, plate 10). 



Mottled phase : In the mottled phase there are equal amounts 

 of reddish brown and pale white, both tints showing as nearly 

 vertical bands on fins as well as body. When the fish is frightened 

 the pale and brown mottling always appears, showing apparently 

 a hiding color, with the fish usually in a corner of the tank and 

 close against the rockwork (fig. 2, plate 10). 



Phase 3 : Whole body pale and colorless, only faint outlines 

 of the brown marks showing. 



Trigger-fish, (Balisfcs caroHnensis). Four phases. 



1. Sides and upper parts and all fins uniformly covered with 

 fine bluish reticulations. Under surfaces white, upper dark. 



2. Uniformly pale, with a yellowish cast. 



3. Pale white, with broad, irregular, vertical bauds on u])i)er 

 body, these sometimes forming black blotches close to dorsal (fig. 

 I, plate 11). 



4. Uniforml\- dusk\-, bluish reticulations sonietiiiies appearing 

 faintly. This is fairly well shown in (fig. 2. plate 11).
