Taking the opportunity of deseribing a monstrous specimen 
of the corona of Echinus sph(cra (O. E. M.), the author proceeds 
to examine whether a radial or a bilateral symmetry is charac- 
teristic of the Echinoderms, concluding with an expression of 
his belief that, both from an anatomical and embryological 
point of view, the Echinoderms belong to the radial type.

These papers are chiefly on the Starfishes {Asterida) of the 
Indian Archipelago and Japan. Some interesting remarks on 
the geographical distribution of this order are prefixed to the 
list of species.

The author gives an account of certain calcareous bodies 
that are to be met with imbedded in certain parts of the peri- 
soma of the Echinoidea, and also in the membrane and its 
reflections that line the interior of their shells.
