Yol. III., p. 49, has previously only been obtained by 

 dredging, was found in rockpools on Bradda Head. 



POLYCHAETA. 



The following new Polychaeta were obtained : — 



Syllis sp. ( ? young monilaris, Sav.), among the rocks 

 below the Biological Station. 



Pionosyllis lamelligera (de Saint-Joseph), dredged 

 near Bay Fine. 



Pionosyllis sp., from the breakwater. 



Odonto syllis ctenostoma (Clpd.), and another species 

 of this genus, which I have not been able to identify, were 

 to be found swimming at the surface of the sea outside 

 the bay on very calm evenings. 



Autolytiis incertus (Mgr.), and four other species of 

 the sexual generation of this genus, were taken in the 

 tow-net at the surface ; one (additional ?) species was 

 dredged near Bay Fine, several sexual individuals being 

 attached to the asexual stock in this ease ; neither of the 

 species of Autolytiis mentioned in the 1898 list was taken. 



Myrianida pinnigera (Mont.) — A fine specimen 

 bearing about a score of sexual ( $ ) individuals was found 

 under a stone, at extreme Ioav water, on the shore below 

 the harbour-master's house. 



NUDIBRANCHIATA. 



I did not pay much special attention to these, but see

 Hancock's monograph are not in the British Association 

 list, though I believe that Mr. Chadwick is aware of the 

 presence of all of them at Port Erin : — 



Doris pusilla, dredged off Bay Fine. 



Boris depressa, Port Erin side of the Calf Sound ; 

 identification a little uncertain, as the specimen escaped 

 before reaching the Biological Station,
