Actually, there is reasonable evidence that simoliophiid snakes 
(Pachyrhachis, Haasiophis) may have re-evolved hind limbs, based on 
their possession of these appendages and their nesting deep in the 
ophidian phylogeny. See Gauthier et al., Bulletin of the Peabody Museum 
of Natural History 53(1), April 2012.
