a. Physiology of fertilization in Paramecium. The chemical nature of the 

 mating type substances and the role of these substances in fertilization 

 is currently being investigated. (Protozoa) 



b. Mechanism of adjuvant-fertilizin agglutination of starfish sperm. The 

 adjuvant action of amino acids in starfish fertilizin agglutination of sperm 

 is being investigated to determine the mechanism of action of these ad- 

 juvants. Asterias and Patvia (Asteroidea) 



c. Antifertilizin and basic proteins. The investigation of the relation of 

 basic and nucleoproteins to antifertilizin is being extended to include a 

 specificity study of basic protein agglutination of sperm. Various marine 

 invertebrate forms including echinoderms.
