them have been discussed by Mesnil (1896) and 

 Hartman (1941a) among others. The most useful 

 distinction is the presence of notosetae in setiger 

 1 of P. caeca. In P. socialis the ridge from the 

 prostomium reaches setiger 4 and the gills are 

 still present on posterior segments. Further, 

 P. socialls lacks spines in the posterior noto- 

 podia but, as these are not distinct in P. caeca, 

 this is not an obvious character.

 is an error since this species lacks an occipital
