Gundlachia is a genus of minute freshwater snails or limpets, aquatic pulmonate gastropod molluscs in the family Planorbidae, the ram's horn snails and their allies.
The generic name is in honor of Cuban naturalist Juan Gundlach (1810–1896).
Anatomy These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch". This serves as a gill as, in their non-tidal habitat, these limpets never reach the surface for air.
Distribution They have a worldwide distribution.Powell A. W. B., New Zealand Mollusca, William Collins Publishers Ltd, Auckland, New Zealand 1979 .
