The anterior end of a specimen of this species, consisting of 50 segments, 

 was dredged in Clew Bay in 18 fathoms. As Mcintosh drew up the descrip- 

 tion from a fragment from which the head was missing, the present specimen 

 enables the account of this species to be completed. I was able to examine 

 the original fragment, and there is no doubt as to the specific identity of the 

 two specimens.
