 Sol aster papposus, Aporrhais pes-pelicani (a very large number, all alive), 

 Lepadogaster bimacidatus. 



3. North side of Fleshwick Bay, 15 fathoms : Solaster papposus, 

 Plumularia pinnata, Eudendrium capillare, Palmicellaria Skenei (new to

 were found (1) var. with abortive cells having ovicells, (2) var. with 

 avicularia on the top of blunt umbones, (3) var. approaching erueifera, 

 but with a spine on the ovicell.
