Section on Nmmnclature, 1st Meeting, Paris, July, 1948. 23 of stabilising the nomenclature of a particular group but are not unanimous on the purely taxonomic question of whether more than one genus is involved. THE PRESIDENT next enquired whether the Section were of the opinion that a resolution in the foregoing terms adequately covered the field traversed in the preceding discussion. On the Section indicating their agreement on this point, the President suggested that some member of the Section should now formally bring forward a proposal that the Section adopt g, resolution in this sense.
