 specifically distinct. The American species is described as having a 

 large, thin air-vessel, without appendages, and numerous small cceca. 

 P. heptadactylus has but four rather large ccecopyloric appendages, 

 and no airvessel. At Pinang it is of very rare occurrence. Of three 

 individuals observed, none exceeded the length given.
