MARINE BIOLOGY AT REDCAR. 



Rev. F. H. WOODS, B.D. 



The meeting of the Marine Biological Section of the Yorkshire 

 Naturalists' Union at Redcar was on the whole very successful, 

 in spite of drawbacks. The coast abounds in marine life ; 

 but this is confined to rocks (scars), which are only exposed at 

 low spring tides, and several of which can only be reached by a 

 boat. The time for exploring is confined, therefore; to barely 

 two hours a day. There was also a stiff gale blowing from the 

 west and north on Saturday and Sunday, and it was not till 

 Tuesday that there was any considerable drift of sea coal and 

 shingle suitable for microscopic examination. 



Of the molluscs the most interesting finds were Dentalium 

 entalis, the empty shells of which are washed up at a particular 

 spot, shewing that there is a small colony of them in the sands 

 to the west of the Pipe Scar, Venus fasciata, which is very rare 

 on the Yorkshire coast, and the beautiful little Philine catena, 

 which is not uncommon at Scarborough. On the Pipe Scar 

 there is a large colony of Zirphcea crispata, and with it the 

 boring variety of Tapes pullastra, as well as a specimen of 

 Barnea Candida, which usually prefers to bore in the softer 

 boulder clay, as at Bridlington.
