Results of the 13 expeditions organized by the Museo Civico di Storia Naturale of Verona to southern China. One-hundred-twenty-five caves were explored, for a total of more than 60 km in length. For each cave we list the progressive number, the cadastral number, the type of research conducted and a short description of the cave. Most of the caves are located in Guizhou Province, in Qianxi County. The hydrogeology, biology, geography and archaeology of the area were investigated during the scientific expeditions. 40 pages, No caves maps, 21 photos.

Cave description:

Aito Dong is the westernmost large sinkhole draining the impervious northern area. As for other sinkholes, the inner cave is very large, enlarged by collapse induced by basal corrosion over alloctonous alluvium. A few hundreds meters from the entrance, the gallery is filled by sediments, but it shortly enlarges again until it reaches a final choke. Water entering the cave progressively curves an entrenchment, leaves the main gallery near the filling area and then disappears in a sump. The subterranean stream, beside the sump, can be reached from two passages: one at the base of the final choke and one from a longer loop branching near the cave entrance. The latter seems to act as an overflow pipe during monsoon floods.
