Century Dictionary and Cyclopedia

1. n. A fish, probably the shad.
2. n. A carangoid fish, formerly Caranx trachurus, now Trachurus saurus, also called saurel, skipjack, and horse-mackerel, of a fusiform shape, with vertical plates arming the entire lateral line from the shoulder to the caudal fin. It reaches a length of about a foot, and is found in the European and many other seas. It occurs rarely on the South Atlantic coast as well as on the Pacific coast of North America. It is sometimes found in immense shoals, and as many as 20,000 have been taken off Cornwall in a net at one time. In Cornwall and some other places it is split and dried salted. Its flesh is firm and of good fiavor, somewhat like that of the mackerel, although generally it is but little esteemed. The name extends to any species of this genus, as T. symmetricus, the horse-mackerel of California, and also to the members of the related genus Decapterus, more fully called mackerel-scad. A species of Caranx (or Trachurops), C. (or T.) crumenophthalmus, is known as the goggler, goggle-eyed jack, or big-eyed scad. See goggle-eyed.
3. n. The ray, Raia alba.
4. n. A dialectal form of scald.
