Description.—In this species the rear margin of the dorsal spine, which is situated over the rear margin of the eye, is armed with a double series of barbs, but the sides of the rounded caudal peduncle bear no spines. The soft dorsal (31 to 33 rays) originates behind the middle of the body, its first ray being much elongated in adults and with a filamentous tip. Otherwis

Filefish (Monacanthus hispidus Linnaeus) 295 Jordan and Evermann, 1S96-1900, p. 1715. Description.—In this species the rear margin of the dorsal spine, which is situated over the rear margin of the eye, is armed with a double series of barbs, but the sides of the rounded caudal peduncle bear no spines. The soft dorsal (31 to 33 rays) originates behind the middle of the body, its first ray being much elongated in adults and with a filamentous tip. Otherwise the fin is rounded in outline, narrowing from the front to the rear. The anal (32 to 33 rays) is below the soft dorsal, and of the same shape except that none of its rays are elongate. The caudal fin is rounded. The pectorals are short, rounded, and situated below the gill open- ing like those of triggerfishes. In the only specimen I have seen the fold of skin that occupies the space between the end of the pelvic bone and the general belly profile—the so-called "ventral flap"— is rounded in outline, not straight as in the illustration, and it extends only slightly behind the tip of the Xt: Fig. 135.—Filefish (Monacanthus hispidus) Color.—Green, varying from bright to olive. The back and sides of young fish are mottled with irregular darker blotches but adults are plain colored. Dorsal spine and caudal fin are green. The soft dorsal and anal fins are pale and translucent. Size.—Maximum length about 10 inches. General range—A tropical species common on the south Atlantic coast of the United States and in the West Indies. It is known south to Brazil as well as from the Canaries and Madeira in the eastern Atlantic and probably from the East Indies. It is not uncommon as far north as Woods Hole. So far its northern recorded limit has been St. Margarets Bay on the outer coast of Nova Scotia. Occurrence in the Gulf of Maine.—Odd specimens of this fi
