sexual behavior very striking, but they are also interesting because 

 rhev occur only under the influence of the molting hormone of the

CLASS SARCODINA 



Syngamy has been reported for a good many representatives of 

 this class, especially for the more highly evolved Mycetozoa, Fora- 

 minifera, Heliozoa, and Radiolaria. The Mycetozoa, on the border 

 line bet\A'een the Protozoa and the Fungi, have been considered by 

 Dr. Raper in his paper on the fungi. 



Order Frotcoviyxa 



Much diversity occurs among the organisms in this group, but 

 generally they have slender, branching, and anastomosing pseudo- 

 podia. Cell fusion has been reported for a few members such as 

 Niiclearia sivtplexhy Dangeard (1886) and Aratari (1889), for Vam- 

 pyrella spp. by Dangeard (1886), and for Chlaviydomyxa moii- 

 tana by Penard (1904a), but nuclear details were not given.
