-titution of his binucleate cells. Binucleate cells, arising 

 by the suppression of cell division after nuclear division by 

 .nitosis have also been produced experimentally in the cleavage 

 cells of Crepidula (Conklin, '12). The two nuclei may divide 

 mitotically and entirely independently although synchronously; 

 in these cases, however, two mononucleate cells are usually 

 produced from the original binucleate cell.
