Fishes; Fishes; Poissons; Poissons. 2454 Bulletm ^7, United States National Museum, m t â i. sal fin long and low, beginning near middle of body, of slender rays embedded in ihe skin; anal similar to dorsal, both connected to the cau- dal fin; tail diphycercal; pectoral fins small, ventral fiua wanting. Vent remote from the head, without papilla. Air bladder none; cseca none. Vertebroi numerous, small. The skeleton does not difl^er essentially from that of Lycodojisia pacificua, with which it has been compared. The skull is not at all depressed, the wide depressed form of the head of the fish is due to the fieshy cheeks. The frontal takes up the greater part of the top of the skull, the parietals are separated by the supraoccipital, whieh extends forward to the frontals. Opercles all present. Lower jaw large and strong. Post-temporal scarcely so firmly attached as in Lycodes; the clavicle long and slender. A» here understood, this family consists of a single species, a shore fish of the Northern Pacific, living in the gravel between tide marks, and diving with great activity into the wet gravel when disturbed. Its relations are apparently with the Zoarcidw. It is not certain that Scytalina has any special afiinity with the Congrogadidw, in which group it was at first placed by Jordan & Gilbert. 930. SCYTALINA, Jordan & Gilbert. Scytalina, Jordan & Gilbert, Proc. IT. S. Nat. Mna. 1880,266 (eerdale). Seytalisctis, Jordan & Gilbrrt, Proc. U. S. Nat. Mus. 1883, 111 (eerdale); substitute for Scytalina on account of the earlier Scytalinus, Erichson, a genus of Goleoptera. Body very long and slender, covered with small scales. Head depressed, shaped like the head of a snake, with tumid cheeks and a distinct neck. Eyes small, superior. Mouth rather large, the lower jaw
