Hamilton, who collected for me at that place; and these, on comparison with several less per- fect specimens in our collections, have established the fact that the normal shape of young and isolated specimens of Eozoon Canadense is a broadly-turbinate, funnel-shaped, or top-shaped form, sometimes with a depression on the upper surface giving it the appearance of the ordinary cup- shaped Mediterranean sponges.
