Comment: Although this species has been recorded from South America several times, it 

 appears that all records are erroneous. Roze, Ofidios de Venezuela, I366, 20$, excludes 

 it from Venezuela. Peters, Copeia, 195^, 57> eliminates it from Ecuador and also removes 

 the name Pseudod i psas f allax Peters, I860, from its synonymy.
