876 THE AMERICAN NATURALIST. [Vol. XXXVIIl. 



In such cases the centre of the protoplasmic area often contains 

 a somewhat more deeply stained material not limited by any dis- 

 tinct boundary from the general cytoplasm, but occupying the 

 position of the single nucleus of other ova and having the same 

 size, and the cytoplasm often radiates from this as a centre of 

 influence. The lesser nuclei do not usually show active division, 

 but are in the resting stage. They show evidences of disorgani- 

 zation in various respects. Some are distinctly vacuolated as 

 the parent nucleus was ; others contain bits of chromatine of no 

 regular shape or position, resembling very closely the " spore-like 

 bodies" found by Herrick ('92) in the "degenerating nuclei" 

 of the yolk cells of the egg nauphus of Alpheus. In a few 

 instances two of these smaller nuclei are still connected by a 

 thread of stainable material, as in Fig. 7, which I interpret as 

 the last stage in amitotic division, and an indication of the proc-
