This species is evidently distinct from P. indicus, differing 

 markedly in having adherent scales and in the coloration, 

 and probably in otlier characters not supplied by Poay's 

 incomplete description, and is entirely diflPerent from Cuhiceps 

 paiiciradiatus, which Jordan and Evermann consider to be 

 identical with it.
