The agglutinating activities of the organs, fluids and spawn from snails and slugs toward various human blood groups has now been examined in detail. The effect of calcium salts and aspects of the variation of agglutinins and hemolysins between individuals of a single species or between species are described in the present paper. Two families of the order Stylommatophora, Vaginulidae and Strophocheilidae, as well as a family of subclass Prosobranchia, order Mesogastropoda, Ampullariidae, represent very primitive groups of the class Gastropoda native to Argentina. O. lactea and H. aspersa are introduced species well known with respect to their serological behaviour. They were studied for possible populational or geographic differences in reactivities. V. solea is a slug of not yet clear taxonomical classification. To some authors it belongs to a new order Systellommatophora which is different from Stylommatophora and Basommatophora (1). Borus, which is of a large size, has a number of morphological features that assign it to Strophocheilidae group A, the most primitive of the family (2).
