Fig. 256.—Winter flounder (Pseudopleuronectes americanus) only about two-thirds as many dorsal rays as the witch (p. 511), lacks the mucus pits characteristic of the left (lower) side of the head of the latter, and has a much larger tail, proportionately. It is oval in outline, about two and one-fourth times as long as wide, thick-bodied, and with proportionately broader caudal peduncle and tail than any of our other small flatfish except its newly discovered relative, P. dignabilis (p. 507). The dorsal fin (61 to 69 rays) originates opposite the forward edge of the eye, and is of nearly equal height throughout its length. The anal (46 to 51 rays) is highest about midway and is preceded by a short, sharp spine. The ventral fins are alike on the two sides of the body, and both are separated from the anal by a considerable gap. The mouth is small, not gaping back to the eye, and the lips are thick and fleshy like those of the dab. The left (under) half of each jaw is armed with one series of close-set incisorlike teeth, but the right (upper) side has only a few teeth, or may even be toothless. The scales are rough on the eyed side, including the space between the eyes, but perfectly smooth to the touch on the blind (white) Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States Fish Commission.
