. Bulletin of the United States Fish Commission. Fisheries -- United States; Fish-culture -- United States. FISHES OF THE GULF OF MAINE 235 90. Moonfish (Vomer setapinnis Mitchill) Shiner; Horsefish; Bluntnose; Dollaiuish Jordan and Evermann, 1896-1900, p. 934. Description.—The very deep, compressed, sharp-edged body of the moonfish (adidts are only about twice as long as deep, and young fry even deeper, relatively), tapering to the usual slender caudal peduncle, and the concave profile of its head, separate it at a glance from pilotfish, scad, crevalle, hardtail, or yellowtail (Chloro- scombrus chrysurus), and the very low dorsal and anal fins obviate any danger of confusing it with the lookdown (p. 236), which is of something the same shape (compare fig. 110 with fig. 111). The first dorsal of the adult moonfish is reduced to four very short, inconspicuous, detached spines, but in young fry the first two of these are elongate and filamentous. The second dorsal fin (21 to 27 rays) and the anal fin (19 to 20 rays) are about equal in length, both of them very low and tapering very slightly from front to rear. In very small fish the second to fourth. Fig. 110.—Moonfish ( Vomer tetapinnii) rays of the second dorsal are more or less elongate, and the anal is preceded by 3 or 4 short detached spines which are not to be seen in the adult. The ventrals are so small that they are apt to be overlooked except in young fry, where the ventral rays, like the dorsal spines, are long and filamentous. The pectorals are falcate, the scales on the lateral line are not large enough to be conspicuous, and the teeth are very small. There are no detached finlets, dorsal or anal. Color.—Described as leaden to greenish above with silvery or golden sides and belly, the second dorsal light yellow at its base and punctated with black, and the pectorals dusky greenish. Size.—About 1 foot long. General range.—Warm seas off the east coast of America from Brazil to Cape Cod, rarely to N
