podia with dorsal and ventral lobes becoming increasingly smaller, 

 but with relatively larger setal lobes ; posterior parapodia with dor- 

 sal rami increasing in relative size (fig. 51, h) and ventral rami 

 decreasing; sixty-fifth parapodium ag in figure 51, h; falcigerous

Anal cirri two, as long as last four segments, somewhat annulated 

 in distal half.
