Abstract
THIS volume contains the papers read at the sixteenth annual congress of the society held at Marburg, June 5–7, 1906. The number of subjects covered by the papers and “demonstrations” is so great that it is only possible to refer to a few. On account of being fully illustrated, special mention must be made of a communication by Prof. L. Plate on the evolution of species in the Bahama land-shells of the pupa group classed under the title of Cerion glans. The gradation from a large-sized, heavily-ribbed, and uniformly coloured type to a diminutive one in which the place of ribs is taken by bands of colour is admirably illustrated in the plate.
