This short report deals with the two cases of the marformations found in Geothelphusa dehaani (WHITE): (1) The malformation of the left third leg; the regenerated arm is found in the base of the propodus. No articulation can be seen. The anterior portion of this arm is similar to that of the normal propodus in shape. (2) The malformation of the right third leg; on the base of the carpus, there are two regenerated fingers which are forming propodus and dactylus with articulations respectively. Each regenerated finger is shorter than the normal one in length.
