The nine species mentioned by Miiller and Troschel, in 1842, as belonginGf- to this area, have increased to one hundred 7 O O •* and fifty-five, which are distributed at various depths. On the flats and reefs, near islands and keys, may be found colonies of Ophiothrix, blue, green, or red, with their translucent thorny arm- spines, and the humble Ophiactis swarming on great sponges; while here and there a yellow or vermilion star marks the soft OpMomyxa flaccida. To the brown gorgonians clings the large Ophiocoma, similar in color ; and sometimes a Medusa-head, whose branching arms excited the wonder of old Rondelet, twines about the thicker stems. These and their companions, living in a strong light, and in warm shallow water, present brilliant and well-marked colors. Nor are those that inhabit the dark and cold depths of the ocean always pale; on the contrary, many are of a bright orange or red. They are peculiar, how- ever, in that their colors generally fade in alcohol; and in an alcoholic collection the shallow species may readily be distin- guished by their brighter 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 Agassiz, Alexander, 1835-1910; U.
