The Great Northern Diver (Colymhus glacialis) is frequently seen upon our northern coasts; they dive with the utmost facility, and live upon fishes and crabs that they catch under water. The Feiiguins (Alcidce) are known by the beak being much compressed and elevated vertically, jDresenting a sharp ridge on its upper margin, and generally grooved transversely. The feet are completely webbed, and have no posterior toe. This family is divided into the Puffins and the Penguins. The Puffins {Fratercula), have the beak shorter than the head, and as wide at the base as it is long, a structure which gives these birds a very remarkable appearance; tlie root of the beak is bedded in n fold of skin, while the nostrils are only narrow slits placed near its mar^^in. Their little wings can scarcely sustain them in the air for an instant. They live upon the sea, and make their nest among KoXv!xfi7]Ti]s, colymbetes, a Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Jones, Thomas Rymer, 1810-1880.
