The following types of central bodies in echinoderm cleavage- amphiasters have been illustrated in other studies. A centriole (or centrioles) without a surrounding " centrosome " is shown by Kostanecki ('96) in Echinus. A centriole (or centrioles) sur- rounded by a " centrosome " (a configuration similar to that il- lustrated by Boveri ('oo)) is shown by Hill ('95) and by Er- langer ('98) in Splicer echinus. A mulberry-like, large, spheroidal structure containing a number of granules (a configuration similar to that of Wilson ('95, '96, 'oo, '28)) is shown by Butschli ('92) in Sphccrcchnius; and by Wilson and Mathews ('95) in Arbacia. A clear, empty area at the center of the aster which may contain some scattered granules is shown by Ziegler ('04) in Echinus; and by Meves ('12) in Par echinus. Whatever the structural details may be and whatever termi- nology is used by an investigator, it is widely taken for granted that central body behavior in echinoderm fertilization is typical of.
