. The Biological bulletin. Biology; Zoology; Biology; Marine Biology. FIGURE 1. Immunodiffusion tols; (1) anti-Homarus sperm, (2) anti-Pagurus sperm, (3) anti-Callinectes sperm (4) anti-Libinia sperm, (5) anti-Limulus sperm, (a) Callinectes sperm extract, (b) Homanis sperm extract, (c) Libinia sperm extract, (d) Pagunis sperm extract, (e) Cancer sperm extract, (f) Liinulits sperm extract. Homarus americanus, Pagunis pollicaris, and Limulus polyphemus (Table III). Three sets of experiments were performed. All antibodies readily agglutinated their own spermatozoa but none of the antibodies agglutinated the spermatozoa of every species. The agglutinations indicate that antigens are on the surfaces of the spermatozoa. Antigens are present over the entire surface since arm to arm, arm to "head" and ''head" to "head" agglutinations occurred. The arm to "head" agglutinations mean that the same antigen appears on the arm and "head." The possibility of arm and "head" specific antigens has not been excluded. The experiments indicate that Llhlnia sperm lias at least two surface antigens, one of which is shared with Homanis sperm. Homarus sperm has at least one antigen which it shares with Pagunis sperm. Lintiiliis sperm has at least three surface antigens, sharing one of them with Pagunis sperm and another with Cancer sperm..
