The greater part of the scaly covering is gone; when the fish was taken out of the water, it was covered with a grey, filmy skin, (so the man said who caught it) but this was so loose that it fell off when the fish began to flounder.

The greater part of the scaly covering is gone; when the fish was taken out of the water, it was covered with a grey, filmy skin, (so the man said who caught it) but this was so loose that it fell off when the fish began to flounder. On large spots on the back and on the head, the scaly covering is partly intact, and the skin here feels like plush to the touch. The scales are very small and are composed of a flat piece, which lies in the skin, and a larger free flat piece, between these two there is a connecting bit. The scales are so thickly set, that the upper parts almost touch each other. The under piece varies very little in size and shape, and the stem starts from the centre. The top piece varies in shape, there are more or less deep cuts on the edge, and there are very frequently several small holes; the stem is here generally speaking placed excentrically. (Text-fig. 2; PL II, figs. 2—5). A thin layer of skin covers the stem and the top part of the scale. After maceration with caustic potash, it is only in the top pieces that there are any signs of structure; parallel to the outer Fig. 2.
