The feet are crowded, a short free portion is cylindrical, 

 bluntly rounded externally, bilabiate, transmitting a fan of 

 delicate setse. 



The stem of the setae is much longer than the appendix 

 somewhat flattened near the end, and with a transverse 

 terminal series of minute teeth. The appendix is short, 

 usually curved, wide at base, rapidly diminishing (f 36), 

 The appendix however may be double the length of the 

 one figured, and less curved. 



The dorsal cirri (branchiae) are somewhat variable in 

 form : but usually broad heart-shaped on the anterior seg- 

 ments (f 33), becoming somewhat narrower, and less 

 bluntly rounded externally further back (f 34), while on 

 young specimens, and on recently renewed lost parts, 

 they are narrower, becoming somewhat lanceolate (f. o5). 

 The ventral cirri (f 37) extend beyond the feet, are nearly 

 cylindrical, bluntly rounded externally. 



Anal cirri shaped much like antennae, maybe as long as, 

 or double, the length of the antennae. 



Color. Head greenish-white. Body from light to dark 

 green. All cirri generally yellowish-green. Body and 

 dorsal cirri with numerous, irregularly placed, dark brown 

 spots. On young specimens and on renewed parts the 

 color is always light, and the brown spots few, or absent. 



Length of longest specimen 50™™. Greatest diameter of 

 same specimen 2™™. 



Found on shells between tides. Occasionally dredged.
