398 ON THE FAUNA AND BOTTOM-DEPOSITS NEAR THE 30-FM. LINE 



Wa7idering species. Asterias ruhcns and A. glacialis are not numerous, 

 and PecUn opcrcv.laris, which is their usual food on these grounds, is 

 also scarce. Ophiura ciliaris occurs in small numbers, and Ophiothrix 

 fragilis is again only represented by small specimens at the roots of 

 hydroids and Cellaria. Falmipes placenta was taken twice (hauls 53 

 and 57), and one or two specimens of Solastcr paj^i^osiis and Henricia 

 sanguinolenta were seen. Echinus miliaris was the only species of 

 Uchinus. 



Bucci7mm undatuiii was common. Stenorhynchus longirostris and 

 Inachus dorsettensis were abundant amongst the hydroids, and Pandalus 

 hrevirostris amongst the Cellaria. Galathea dispersa, Porcellana longi- 

 cornis, Eiirynomc aspera, Portunus depurator were also common, together 

 with Eupagurns Bernhardus, associated with Sagartia parasitica or 

 Hydractinia echinata, and Eupagurus Prideauxii, associated as usual 

 with Adamsia palliata. 



Fishes were more numerous here than on any other ground upon 

 which the trawl was used. The species most plentiful were Pleuro- 

 nectes limanda and microcephalus, Trigla pioii and gurnardus, Callio- 

 nymus lyra and Gobms Jeffrey si.
