Among the flatfishes the plaice is like the halibut and unlike the flounder and its relatives in having a very large mouth with well developed teeth, the mouth indeed being so large that its angle is well back to the middle of the eye. Unlike the halibut it has along the middle of the body an almost straight 'lateral' line, which is without any arch near the head, and it differs from both the halibut and turbot in having the end of the tail rounded instead of concave or hollow. Finally the plaice differs from the window-pane, which also has a rounded tail and a large mouth, in having the eyes on the right side of the body instead of on the left side, and in not having a distinct arch in the 'lateral' line near the head. It alone of our flatfishes has these three characters combined—large mouth, almost straight lateral line, and rounded tail (see figure 2). The Nea lateral line ^-SS^sJfi^iS^- Rounded tail. ,/,tt-: \ Large mouth Fig. 2.—Plaice fifteen inches long from Le Have bank, off Nova Scotia. After H. L. Todd. colour of the plaice is a uniform light or dark reddish-brown, although there- is a series of from three to five dark spots along each side of the body. These are, however, usually distinct only in the young (see figure 1), but occasionally they are to be seen in quite large and old fish. Another character that is familiar to any one that handles the fish is the very distinct roughness of the sur- face, which is caused by the small, but sharp teeth on the free edge of each scale (see figure 11)..
