Gulf Stream flounder (Citharichthys arctifrons Goode)"' Jordan and Evermann, 1S96-1900, p. 2683. Description.—This little fish is left-handed (eyes on the left side and guts at the left) with a moderately wide mouth gaping back as far as the forward edge of the eye, a nearly straight lateral line, and with both pectoral fins well-developed, though the one on the eyed side is considerably larger than its mate on the blind side. The left ventral fin is on the midline, the right fin a short distance above it on the side, and while these two fins are alike in females, in males the one on the blind side is much the longer of the pair. The body is ovate in outline and very thin. The long fins are of moderate breadth, with the dorsal fin (about 83 rays) originating over the forward margin of the eye and the caudal fin rounded. The scales are so large that there are only about 40 rows of them along the lateral Fig. 271.—Gulf Stream flounder (.Citharichthys arctifrons) This species parallels the summer, four-spotted, and sand flounders (the latter its closest Gulf of Maine ally) in its left-handedness, but it is distinguishable from all of these by the fact that its lateral line is almost straight and likewise by the great disparity in size between the two pectoral fins and by its very large scales. Its narrow form and the fact that none of its dorsal fin rays are branched are further points of distinction between it and the sand flounder, and it is much smaller at maturity than any of the flatfishes common within the Gulf. Size.—Kipe females 3}^ to 4 inches in length have been recorded, suggesting that this is about the maximum size. '• A second species of this genus (C. unicornis) may be expected on the outer slope of Georges Bank in depths of 100 fathoms and more, since it has been taken o£f Marthas Vineyard
