POLYCILETA OF THE L.M.B.C. DISTRICT. 239 



Sthenelais zetlandica, M'Intosh. 



The mutilated fragment mentioned by Mr. Gibson* as 

 dredged from 20 fathoms off Port Erin remains without 

 successors. 



Pholoe minuta, (Fabricius). 



Dredged, Whitsuntide, 1890, in Menai Straits. Car- 

 rington records it as rare at Southport. 



Webster and Benedict + record it from Massachusetts, 

 U.S.A. and it has an exceedingly wide range within the 

 Arctic circle. This is an interesting form, as through the 

 structure of its falcate compound setae it hints at the 

 not distant relationship of the Syllidae with the Polynoidae. 

 Family. — Aphinomid^e . 

 Sub-Family. — Hipponoin^e. 



*S2)inther oniscoides, Johnston. 



Six specimens of the usual yellow hue were dredged 

 during the "Hyaena" cruise, Whitsuntide, 1890, from 

 about 17 fathoms, off Holy Island, Anglesey. As they 

 were picked from off the yellow hydroid Antennularia 

 ramosa and also from the yellow Halichondria panicea — 

 to both of which they assimilate absolutely in colouring — 

 they furnish another addition to the long list that is 

 accumulating of protectively coloured animals. 

 Family. — Eunichle. 

 Sub-Family. — Eunices. 



*Eunice harassii, Au. and M. Ed. 



Hab : 12. Dredged from 21 fins. 



I refer this single specimen to the above species with 

 some hesitation as in the spirit preparation the character- 

 istic spots on the dorsum do not show, and again the 

 filaments to the largest branchiae are more numerous 

 — (20) — than is given in previous diagnoses of this species.
