ADDENDUM: 



Since submitting this manuscript for publication, two additional publications have 

 come to light which are pertinent to this subject and warrant mentioning. Suzuki and 

 Higasa (1962) found variable agglutinins for certain tuna species in seed extracts of 

 Glycine max. Ginkgo biloba. and I irgilia divaricata. They found certain sugars to be inhibi- 

 tory to some of these agglutinins and noted that agglutinability was destroyed in each 

 extract by heating at 80^ C. for 30 minutes. Sindermann (1963) found seed extracts 

 of certain lima bean strains, and large lentils to give differential reactions in three 

 clupeoid species indigenous to coastal areas of the northwestern Atlantic. Evidence 

 was obtained for heterogeneity in four spawning populations of alewives 

 (Alosa pseudoharengusj.
