Immunological species specificity of sperm‐binding protein from eggs of the 4 sea urchin species, Hemicentrotus pulcherrimus, Pseudocentrotus depressus, Anthocidaris crassispina and Temnopleurus toreumaticus , was examined by means of double immuno‐diffusion technique in agar. Ca‐soluble fraction of sperm‐binding protein which is considered to be responsible for initial sperm‐egg bonding at fertilization, has species‐specific antigenic component. Correlations in antigenic constituents among the 4 species are described.
