The side patch of the guinea-pig lies chiefly posterior to the middle of the body and frequently extends well back, covering the greater part of the hip and hind leg, while the sacral patches maybe so small and closely approximated that they seem to form an unpaired area at the extreme posterior end of the body (figs. i, 5, and 7). The pigment patches are apparently not correlated with internal structures, such as the distribution of blood vessels or nerves. They are epidermal in origin and subject to more or less apparent asym- metry and mutual displacement, as if they were derived from distinct groups of ectodermal cells endowed in many cases with distinct pig- * In figs. i-S, solid black indicates black coat; black stipple, red coat; white stipple on black ground, red and black hairs 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 Carnegie Institution of Washington.
