Lactate NAD oxydoreductase, occurring in five species of Sphaeroma, enable us to disclose homologies for some fractions which are the more numerous as the species are more nearly related. S. serratum stands clearly apart and the couple S. rugicauda and S. hookeri form an opposite extreme; S. monodi and S. teissieri offer some affinities.
