Messrs. Meek and

Worthen and Dr. Lütken, on the other hand, regard it as asso-
ciated in some way with the alimentary canal and the function of
nutrition.

The author strongly supported the latter opinion. The peri-
visceral membrane in Antedon and Pentacrinus already alluded
to, which lines the whole calyx, and whose involutions, support.
ing the coils of the alimentary canal, contribute to the formation
of the central columella, is crowded with miliary grains and
small plates of carbonate of line ; and a very slight modification
would convert the whole into a delicate fenestrated calcareous
plate. Some of the specimens in Mr. Wachsmuth's collection
show the open reticulated tissue of the central coil continuous
over the whole of the interior of the calyx, and rising on the
walls of the vault, thus following almost exactly the course of
the perivisceral membrane in the recent forms. In all likelihood,
therefore, the internal calcareous network in the crinoids, whether
rising into a convoluted plate or lining the cavity of the crinoid
head, is simply a calcified condition of the perivisceral sac. In order to make the curves fairly comparable, both in regard
