tion, says that the P. pilosimanus obtained were associated with an 

 EjnzoantJms, but no further mention is made of the latter, which 

 may have been E. paguriphilus. 



POLYTHOA INCRUSTATA, SttTS. 



Several specimens from Station 5, 70 fath. Associated with 



Eupagurus meticulosus . 



PoLYTHOA, sp. incert. 



The difficulty of identifying the species of this genus from spirit 

 specimens is so great that I have given up the attempt in this 

 instance. The specimen obtained was from 90 fath. at Station 5. 



Hydrozoa. 

 Perigonimus arenaceus ? 



Growing on a Fucus shell in 200 fath. 



EUDENDRIUM RAMEUM, Pall. 

 TUBULARIA INDIVISA, Limi. 

 TUBDLARIA CORONATA, Ahild. 



DiPHASiA PINASTER, ElUs and Sol. 

 Sertularella Gayi, Lam. 

 Aglaophenia myriophyllum, Linn. 

 Antennularia antennina, Flem. 



With the exception of Perigonimus , all the Hydroids were trawled 

 from moderate depths. 



In addition to the trawling I made frequent use of the tow-net, 

 but was somewhat hampered by the necessities of the cruise. At 

 night we were anchored, and the tides were seldom strong enough 

 to keep my net extended ; during the day we were working rapidly 

 along the lines of observation, when tow-netting was impossible, or 

 we were trawling, when it was difficult. I did most of my work 

 during the trawling, but whenever the paddles were moved — and 

 they had to be moved pretty often to keep the ship^s head up — I ran 

 the risk of losing my net. 



I was anxious to make a comparison between the surface fauna 

 outside Plymouth and that at the entrance to the Channel, in order 

 to settle the question whether there is a current setting in towards 

 the Channel, and carrying the numerous southern and Atlantic forms 

 which are from time to time taken on the south-west coast in an 

 easterly direction. Such a current, if it existed, would be a part of
