These birds are the Auks of the Arctic and the Penguins of the Antarctic regions, and their external similarity lies in the fact that in both the legs are set so far back on the body that the birds assume a man-like posture, and are clumsy and uncouth in their appearance on shore. In the water both are expert swimmers and divers, though here again they differ in that the Auks use their feet in swimming, whereas the Penguins swim entirely with their wings, and use their feet only in steering their course. The Auks, Murres, and Puffins include diving Arctic sea-birds grouped under the scientific name Alcida, and embracing about a dozen genera and some thirty species. All members of the family are essentially birds of the Arctic regions, and are especially numerous on the Alaskan and Siberian coasts. Though the Auks resemble the Penguins superficially and in their habits, anatomically their nearest relatives are the Loons and Grebes. From the Loons, however, they differ in lacking a hind toe, and from the Grebes in the possession of a well-developed 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 Pearson, T.
