FISHES OF THE GULF OF MAINE 73 Occurrence in the Gulf of Maine.—The cow-nosed ray has even less claim to be called a Gulf of Maine fish than have the sting rays just mentioned, for while it is often taken in the traps at Woods Hole—145 in one day on one occasion—and is recorded from Nantucket, it has never actually been seen east or north of Cape Cod. Chimjeroids. Subclass Holocephali THE CHIMERAS. FAMILY CHIM-ERIDiE The chimreras find their nearest affinities in the sharks but are separated from the latter by many important anatomic characters, the most obvious of which are the facts that there is no spiracle, there is but one gill opening on either side, the tail is symmetrical, and the gills are fringelike and free at the tips like those of bony fishes. In general aspect the chimseras remotely suggest the grenadiers (p. 467), but are easily separable from them by the location of the ventral fins, which are set far back under or behind the tips of the pectorals; by the fact that the fin on the back is separated by a deep notch into dorsal and caudal portions; by the very small eye; and by the large size of the pectoral fins, to list only the most obvious differences. There is no danger of confusing them with any other Gulf of Maine fishes, so curious is their ^u^ Fio. 31.—Chimrera (Chimxra affinis) 30. Chimsera. (Chimsera affinis Capello) Jordan and Evermann, 1896-1900, p. 95. Description.—The chimera is deepest (one-seventh to one-eighth as deep as long) just behind the gills, tapering gradually backward to a weak slender tail, and is very soft bodied. The head is short, its dorsal profile oblique and prolonged into a short, soft, conical knob above the mouth. The forehead of the male bears a curious cartilaginous hook, armed with recurved prickles on its lower surface, which probably serve to clasp the female. The mouth is inferior i
