Synopsis.—Dorsal 37-40; anal 31-32; pectoral 33-37; pyloric coeca more than 200. Disk in the head. Gill slit typically extending down in front of 1 to 4 pec- toral rays, some- times appearing to be above the fin. Teeth simple and trUobed, elongate, recurved. Dorsal fin deeply notched, . 1 , 1 Figure 20.—Polypera greeni. Teeth from type connected to less than the basal fifth of the caudal fin. Color a light brown. A large species, reaching a length of 244 mm. RemarJcs.—The Bering Island specimens differ in certain respects from the type as wUl be seen by the following notes on these specimens. Head wider than deep; cheeks swollen. Maxillary reaching posterior margin of eye. Spout somewhat depressed, the upper jaw slightly overlapping. Greatest depth of body at front of first dorsal. The gUl slit is either above the pectoral or extending down in front of one or two rays. Vent separated from the disk by less than the diameter of the disk. Origin of dorsal above middle of pectoral and midway between the disk and vent. A shallow notch between the dorsal and caudal fins is present in the large specimens as figured in the type, absent in the smaller specimen. The two large specimens colored a soft brown as the type. The smallest specimen faded out to an ashy brown. Peritoneum pale with scattered dots, POLYPERA BERINGIANUS (Gilbert and Bnrke) Liparis callyodon Starks, 1911, p. 196.
