Reinarks. — This species is probably nearest related to Spelerpes 

 {Oediyus) imrvipes Peters, from Colombia, but the latter differs in 

 many important particulars, being described as having only 17 costal 

 grooves, a single patch of parasphenoid teeth and "lingers and toes 

 little developed, united." 



There are two other Central American salamanders having 19 costal 

 grooves, but they belong to different genera. One is Oedipina uni- 

 formis Keferstein, which has a perfectly worm-like habitus, rudi- 

 mentary digits and a single parasphenoid patch. The other is Cope's 

 Haptoglossa pressicauda, which has the tongue adherent in front, while 

 in the species here described the tongue is typically boletoid.
