Summary In summarizing the foregoing pages, the following points may be noted as of particular interest: 1. All the species comprised in this small collection are terrestrial forms, and they appear to be identical with the recent gastropods of the province. 2. These forms, except Cyclophorus youngi, a new species here described, are all represented in living state, and were originally described either from the same province or from its neighbouring districts. 3. Some of the species are rather widely distributed in east, central and south China. 4. The geological age of these gastropods, judging from its close resemblance to the recent forms, seems not to be earlier than the Middle Quaternary or the Pleistocene Epoch, or it may even belong to the base of the Upper Quaternary. Any further suggestion in regard to this question can only be made by examining additional collections around the locality where this collection was made.
