This species is fairly abundant in Blacksod Bay and Clew Bay, especially 

 in Laminaria roots. It is easily recognized by the dark black pigment stripes 

 on the anterior segments, which remain for some time in preserved specimens. 

 In the parapodia of the posterior segments there is a thick simple bifid seta 

 ventrally, and a slender curved faintly bifid seta dorsally. Mature specimens 

 were found in March.

 roots. Dredged in 1 fathom. Cleat Bat — Dredged on 

 seven occasions, in 7-26 fms. Bofdc Harbour — Taken in
