A comparative study of proteinograms and zymograms (LDH, MDH) has been carried out at different ontogenic stages, in Ambystoma mexicanum (A.m.), Ambystoma dumerilii (A.d.) and nucleocytoplasmic hybrids 2 n A.d/cytoplasm Am. It appears that 2 n A.d. nucleus, grafted in A.m. cytoplasm expresses only a part of its potentialities, which could account for lethality of the nucleocytoplasmic hybrids.

1.The study of blood serum proteins by different electrophoretic techniques provides a way to study speciation characters among dolphins.2.2. The electrophoretic analysis has allowed at least twenty-one constituents to be numbered in Delphinus delphis; twelve of these have been antigenically defined with an anti-D. delphis antiserum. The electrophoretic and immunoelectrophoretic analyses of serum proteins in the species Stenella styx have shown that the two species are almost identical at the serum protein level.3.3. Only sixteen constituents are numbered in the serum of Grampus griseus, twelve of whic have been antigenically defined with anti-D. delphis and anti-S. styx antiserums and are common to the three species.4.4. Seventeen constituents are numbered in the serum of Globicephala melaena. After the antiserums anti-D. delphis and anti-S. styx have been drained by G. melaena serum, they still posses one antibody which reacts with a β-1-globulin present in D. delphis, S. styx and G. griseus serums. This β-1-globulin appears to be lacking in G. melaena serum.5.5. Other differences have been shown between the group formed by D. delphis and S. stys and the two other species, particularly at the transferrin level.6.6. The existence of a group system of transferrins has been shown among D. delphis and S. stys.
