It resembles the gag very much in its general appearance and in the shape of its body, with a somewhat larger mouth and more projecting lower jaw, also a larger caudal fin, which is more crescentic or scythe-shaped. The depth of its body is about a third of its length. The teeth are in narrow bands, with two canines in each jaw, but these are not so strong as in the Cuban form, and those in the upper jaw are not directed so much forward, nor the lower ones so much backward. The caudal fin is concave or crescentic, and the scales are larger than those of the gag. The color is pinkish gray above, paler purplish gray below; the upper part of the body and head is covered with small, rounded, irregular dark brown spots; the sides and caudal fin with larger and longer pale brownish blotches, somewhat reticulate; fins dusky, some edged with white. Its habits are similar to those of the gag, just described, in whose company it is found. It grows to a length of two feet or more, and to ten pounds or more in weight. The remarks concerning the tackle and fishing for the gag apply equally as well for the scamp. This fish, with the gag, is sometimes taken on the snapper banks by the red-snapper fishermen, though it is not shipped to the northern markets as it does not bear transportation so well as the red-snapper, and is sold for home consumption or eaten by the crews. I first saw this fish as has just been related, in 1877, when it was caught by a Kentucky friend, and it had very much the same appearance as the gag. We then decided that both fish were scamps, my friend remarking that "The only difference is that this fellow seems to be more of a scamp than the other one," an opinion I fully indorsed. The scamp does not stray so far north as the gag, being confined to subtropical regions. It is regularly taken to the Key West market by the commercial fisherman, where it commands a ready sale, being well esteemed as a food-fish. The first specimens I afterward preserved were secured from this source. THE YELLOW-FINNED GROUPER (_Mycteroperca venenosa_) This grouper was first noticed by Catesby, in 1743, from the Bahamas, and was named by Linnæus, in 1758, who bestowed the specific title _venenosa_, or "venomous," as its flesh was said by Catesby to be poisonous at certain times. It is common at the Bahamas, and from the Florida Keys southward to the West Indies, and perhaps to South America. Its form is very similar to the gag and scamp; its depth is a third of its length. Its head is as long as the depth of the body, and rather blunt, with the profile somewhat uneven, but curved; the mouth is large, with narrow bands of teeth, and two canines in each jaw which are not directed forward. Not much is known concerning this fish, as its flesh is reputed to be poisonous at times, and it is seldom eaten.
