THIRPEENT EH ANNUAL REPORT 119 
2. Pale silvery, with a greenish cast, unmarked. (see upper 
figure on plate opposite page 438, American Food and Game 
Fishes.) 
3. Color under excitement; same as preceding, but with five 
irregular, vertical bands of brownish black. Shown faintly 
in lower figure of the plate referred to. It is better defined on 
colored plate 25, Fishes of Porto Rico, but neither show the 
remarkably sharp bands affected by specimens in the New York 
Aquarium. 
SERGEANT Major, (Abudefduf savxatilis). Banded phase: 
Body pale, with five or six vertical black bands. Frequently the 
pale areas between the bands become yellow. 
Dark phase: Body and fins nearly black, vertical bands on sides 
almost obscured. 
Alarm phase (in the photographic tank): Same as preceding, 
but vertical bands more distinct, with a white band across fore- 
head and a white blotch under eye. 
GRAY SNAPPER, (Lutianus griseus). Three phases: 
1. Uniformly pale, dusky above, lighter on head and under sur- 
facencheat plate 12). 
2. Uniformly dark olive brown, still lighter below. 
3. Coloration under excitement: The whole fish becomes a 
shade darker, with a heavy black band, the width of the eye, ex- 
tending from snout obliquely through eye to front of first dorsal 
fin. A narrow fringe of black appears on dorsal and anal fins 
(fig. 2, plate 12). 
This is also fairly well shown in American Food and Game 
Fishes, on the plate facing page 432. The brilliantly colored 
phase on plate 17, Fishes of Porto Rico, has not been observed 
among specimens in the Aquarium, except as it has been indi- 
cated occasionally as a faint suffusion of color. 
ScHOoLMASTER, (Lutianus apodus). Ordinary coloration: 
Above dusky olive. Yellowish olive below and on all fins, no 
markings anywhere. 
Excitement phase: Narrow vertical bands come out sharply 
on upper part of body. Feeding usually develops the bands dis- 
tinctly. 
Phase 3° The brilliant yellow coloration shown in plate 19, 
Fishes of Porto Rico, is probably correct, as the painting was 
made from a living fish held in the portable tank. This colora- 
tion probably results from fright, it has not been observed in
