cular cirri short, a little longer than the transverse diameter of 

 the buccal segment. Dorsal cirri rather long. Ventral cirri 

 sliort and conical. Branchiae commencing about the third seg-

Feet : — Simple setae long, lanceolate, acutely pointed, and finely 

 toothed or serrated on the inner edge or margin for a part of 

 their length. Pectinate setae small, apparently few in number, 

 and with few pectinations or teeth. Compound setae short, about 

 half the length of the others ; falciform appendage with a sharp
