This species was first described by Dr. Holbrook, in 1859, from the coast of South Carolina. He named it _thalassinus_, or "pertaining to the sea," from its supposed habit of living in deep water. It is either a rare fish or it has been confounded with the common weakfish. It has been recorded from several places on the South Atlantic and Gulf coasts, in Virginia, South Carolina, Florida, and Mississippi. It is supposed to inhabit the deep water of the sea and Gulf, though this is by no means certain. Its form is very similar to the spotted weakfish, with a more pointed snout and somewhat larger eye; otherwise it is much the same. Its color is brownish above, lighter below; the middle of the sides is marked with many dark dots; there is a dark blotch on the upper part of the cheek; the first dorsal fin is black, the second dorsal and anal fins are dusky, and the other fins pale. The same remarks as to fishing for the spotted weakfish will apply as well to this species, if the opportunity should occur to the angler. It is a doubtful species at best, and may eventually prove to be an aberrant form of the spotted weakfish. THE BERMUDA CHUB (_Kyphosus sectatrix_) _Kyphosus sectatrix._ The Bermuda Chub. Body ovate, somewhat compressed; head 3-3/4; depth 2-1/8; scales 10-55-16; D. XI, 12; A. III, 11; head short, with blunt snout; mouth small, maxillary reaching front of eye; each jaw with a series of narrow incisors, implanted with compressed conspicuous roots posteriorly; behind these a narrow band of villiform teeth; fine teeth on vomer, palatines, and tongue; teeth 35 to 40 on each side; preopercle weakly serrate; top and sides of head finely scaled; interorbital region gibbous, below which point snout is truncate; soft dorsal and anal very low; second anal spine highest; caudal well forked, the lower lobe longest; gill-rakers long; dorsal spines depressible in a groove of scales; small ctenoid scales entirely covering the soft portions of the vertical fins, and extending up on the paired fins. The chub belongs to the family of rudder-fishes, _Kyphosidæ_. It was noticed as _sectatrix_ by Catesby in his "History of the Carolinas," in 1738, and was so named by Linnæus in 1758. _Sectatrix_ is the feminine of _sectator_, meaning "one who follows," in allusion to its habit of following vessels. Its range is along the South Atlantic coast to the West Indies, sometimes straying as far north as Cape Cod in the summer. It is common on the west coast of Florida.
