1941 CATALOGUE OF FISHES OF TORTUGAS HO 



ing: "Body in banded phase grayish yellow. Each scale seems to have a yellow 

 spot on grayish background, thus showing under lens a series of longitudinal 

 yellow lines. In banded phase narrow lighter lines separate the dark bands, of 

 which the first passes from anterior base of spinous dorsal through the pectoral 

 base." A brown line, slightly wider than the pupil, extending from snout through 

 eye to above posterior margin of opercle, and two narrow pale ones on the cheek 

 seem to occur in both color phases mentioned. 



An adult as observed in nature is described as dull brownish, this color being 

 broken by bands; fins yellowish. Concerning a specimen between 125 and 150 

 mm. in length Dr. Longley observed, "In banded phase, lightens very distinctly 

 in shade in passing from algae to bare sand."

Lutianus analis (Cuvier and Valenciennes). Muttonfish 



(Plate 10, figure 1) 



Jordan and Thompson (Bull. U. S. Bur. Fish., vol. 24, 1904 (1905), p. 241) re- 

 ported that the muttonfish was caught in Bird Key channel in 8 fathoms. Dr. 

 Longley listed it from reefs at Loggerhead Key, Bush Key, Long Key, Bird Key, 

 and "inner lighthouse reef," and from White Shoal. This snapper evidently is 

 common in the vicinity. At Key West it is perhaps a little less numerous than 

 Lutianus griseus, which it outranks, however, in importance as a food fish. 



Records of the examination of 29 stomachs were found among Dr. Longley 's 

 notes. Fish, largely small grunts, predominated as food. The only other food of 

 any importance consisted of shrimps. Dr. Longley noted that this species, like the 

 gray snapper and the schoolmaster, is a nocturnal feeder. 



This snapper has a barred and a "self-color" phase, as indicated by Dr. Long- 

 ley's statement in a field note: "On a bit of broken bottom near boat's moorings 

 found half a dozen L. analis, 12 to 14 inches long. They were invariably banded 

 when resting on bottom, whether with or without cover, and invariably changed 

 to a self-color, except for minor reticulations and vermiculations, when swim- 

 ming." A second observation confirms the first: "Resting muttonfish, 12 to 14 

 inches long, barred; not so when swimming." A third observation reads: "Large 

 L. analis, 18 inches long, resting on bottom on shady side of coral head, dark and 

 conspicuously barred. It swam off slowly as I approached, becoming much lighter 

 with bands showing faintly." 



Brazil, West Indies, to Florida, straying northward in the Gulf Stream.

Lutianus jocu (Bloch and Schneider). Dog snapper 



(Plate 10, figure 2; plate n, figure 1) 



Lutianus jocu is much less abundant than L. griseus and L. apodus, but may 

 always be found without great difficulty. It tends to collect near Orbicella stacks, 

 the jagged Palythoa-covered reefs, submerged wreckage, and like places.
