This proves that the Seals from the different parts of the west coast of America are distinct from each other, each specimen having a specific geographical range. 16. ARCTOCEPHALUS. Muzzle rather tapering in front. Cutting-teeth |-, upper nearly square. Grinders |i|. Palate of the skull rather narrower behind than in front, short, scarcely reaching to the middle of the zygo- matic arch. Lower jaw-bone narrow, rounded below, without any angle behind. The face and skull rather elongate; the forehead flattened, and nearly horizontal from the nasal bone to the vertex ; the palate rather concave, contracted behind, short, not reaching bej'ond the middle of the zygomatic arch ; the nose-aperture large, high ; the lower jaws moderate, with a crest-like ridge behind, beneath, just in front of the condyle. The crest-like process on the hinder part of the under edge of the lower jaw difiers somewhat in shape and development in the different species; but it nowhere resembles the flat expanded disk found in a similar situation in the lower jaw of the preceding genus. Nose simple, with a rather large callous muffle above and between the nostrils. Whiskers cylindrical, thick, round, tapering, not waved ; hinder ones largest. Ears with a subcylindrical, distinct, external conch. Fig-. 17,. Arctocephalus Hookeri. Skull, palate, and grinder. The fore feet elongate; the palms bald, longitudinally grooved; claws five, very small, rudimentary, scarcely visible. Hind hmbs rather produced ; the legs free. The hind feet elongated ; the soles bald, longitudinally grooved ; the toes subequal, short, webbed, and each furnished with a long membranaceous expansion, the web and the membranaceous expansion Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration an
