Data are presented on the distribution of the Gm and Inv allotypes of human IgG in samples from Melanesian populations, three from Malaita and three from Bougainville of the Solomon Islands. The Lau from Malaita are polymorphic for the phenogroup, Gm 1, 2, 5, 13, 14 . This phenogroup is not known to be polymorphic in any other population of the world. The Inv 1 frequencies of the populations from Malaita are lower than the lowest observed in samples from Bougainville, and this may indicate an extension of the north‐south cline for Inv 1 previously reported for Bougainville. Samples from Aita in the north of Bougainville and from the Nagovisi in the south confirm the existence of the north‐south cline for Inv 1 in Bougainville and suggest the presence of a Gm cline.
