the large tanks of the New York and Bermuda Aquariums, and 
the specimens were not tested in the photographic tank. 
QueEEN TRIGGER-FISH, (Balistes vetula). This wonderfully 
marked fish has three phases of coloration: one dark, another pale 
and a third with the fins almost black. The usual blue markings 
persist in all three without change, except in intensity. In the 
dark phase, which is the customary dress, the head, below the blue 
lines, is rich golden yellow, all blue markings are brilliant, the 
body and fins dusky olive, especially above. 
The pale phase is quite a change from this, the whole body 
becoming yellowish white, the blue markings still persisting 
faintly. 
The coloration shown on plate 39, Fishes of Porto Rico, is that 
of a dead and half-faded specimen. 
Live specimens observed in Bermuda frequently showed the fins 
black, the lower part of the body rich purplish blue. 
’ Cow Fisu, (Lactophrys tricornis). Phase 1: A uniformly pale 
or yellowish olive phase, with purplish blue reticulations very 
distinct. 
Phase 2: Large, very dark blotches spread over body and tail, 
blue reticulations scarcely apparent. 
Phase 3: Whole body light brown, blue reticulations becoming 
dusky. 
Biue-Heap, (Chlorichthys bifasciatus). Phase 1: Hinder 
half of body indigo blue, like the head, the black-bordered whitish 
band between, taking a bluish cast. 
Phase 2: A sudden change from this leaves the hinder half of 
body pale greenish yellow, upper and lower rays of tail bluish 
black and the white band showing pure white. 
“Ciuck,” (The Bermuda name) (Eques acuminatus). Pale 
phase: Pale silvery, the longitudinal rich brown stripes of body 
very distinct; first half of spinous dorsal rich brown. 
Dark phase: Uniformly dusky brown on body and fins. Two 
or three darker vertical blotches occasionally appearing. 
Note.—Mr. L. B. Spencer has kindly furnished photographs of 
vellow-fin grouper, hogfish, red-parrot and trigger-fish.
