This genus is highly characteristic of the lienio nearctica, where five

 nosns, P. eincreus) undergo their metamorphosis while quite small. 

 The last uanu'd, and probably P. (ilntinoNus, never enter the water, but 

 are hatched in damp places on land. The branchiie have therefore 

 no functional service. The species are as follows-
