We may also notice that the genera of which we so frequently find the dead tests are the same which have been known as characteristic of the West Indies since the earliest tertiary. We cannot expect to find represented among the fossils the Echinothurise, Pourtalesise, and many of the Echinidie, since after death they read- ily fall to pieces, and may then be dis- solved, like many species of mollusks, at great depth, before they become protected by a covering of deep-sea 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.
