The data collected were interpreted as providing evidence of the continual Mendelising which occurred in the collar of hybrid birds.—E. G. Boulenger: Two new species of tree-frogs from Sierra Leone.—E. Heron-Allen and A. Earland: Foraminifera of the Kerimba Archipelago, Portuguese East Africa. Part ii.
