* SCALISETOSUS ASSIMILIS, McIntosh. 



This species has recently been found upon the oral region of 

 Ecldnus escidcntus, Mr. K. A. Todd bringing it to my notice, I think 

 I am justified in saying that it is not uncommon.

POLYNOE SCOLOPENDRINA, Savigny. 



Mcintosh (20) gives the habitat of this species as the tubes of 

 Polymnia {Tcrcbclla) ncbidosa, between tidemarks, Herm, and between 

 the chinks of rocks (gneiss), in muddy sand in the burrows of Lysidice. 

 Other authors confirm the residence of this species more or less closely 

 with Folymnia 7ichdosa, while de St.-Josepb (31) states that it is found 

 on the shore under stones, where it constructs a tribe of sand and bits 

 of shell.
