ching. The dorsal cirri are placed in a series, anterior to 

 that of the branchiae ; both are long and slender, projectino- 

 beyond them. The position of the lateral cirrus corresponds 

 to the region between the third and fourth gill. In front 

 of the branchiae is a double row of forked bristles, the shaft 

 of which is beset with small spines; among them some ringent 

 bristles, of the type of E. foliosa, are to be found. The 

 neuropodium has a rounded, ear-shaped, anterior lip and 

 is provided with a fascicle of bristles, some of which are 

 very elongated, equal to two thirds of the breadth of the body.
