Smith, F.Z.S., Assistant Keeper of Zoology, British Museum. Previous to the researches of Mr. and Mrs. Bent, only forty-eight land and freshwater molluscs had been recorded from Sokotra. In addition to twenty-three of these species, they were fortunate in obtaining eleven new forms, some of them very remarkable. These have been described and figured by the writer in the 'Journal of Malacology,' vol. vi. pp. 33-38, plate v., figs. 1-9. and in the 'Bulletin of the Liverpool Museum,' vol. ii. No. 1, p. 12. The British Museum is much indebted to Mrs. Bent for the donation of this valuable collection. A. Terrestrial Species
