SOME WHITBY POLYZOA, ETC. 



S. LISTER PETTY, 



Ulverston. 



Without daring- to say definitely that nothing- has been done in 

 Polyzoa, etc., from Whitby and neighbourhood in recent years, 

 I can hardly be far wrong, I fear, in stating that little has been 

 written.. Dr. Hincks, in 4 Brit. Marine Polyzoa,' 1880, locates 

 one species only, Buskin nitens, from Whitby, whilst in the 

 ' Zoophytes' he gives several species from the locality. 



To collect satisfactorily on the Scar a pair of sea-boots would 

 be useful, if heavy, but my specimens were gathered without 

 such aid, and did not entail more than a change of boots ; for 

 with the thermometer at i30°F. in the sun (31st July 1899) at 

 mid-day no collecting was advisable which required exertion. 

 So then the list must be taken as a sort of holiday task, some- 

 thing to keep the list-maker out of mischief and give an excuse 

 for idling about the shore, instead of scouring the surrounding 

 country— ' doing Yorkshire,' in fact. 



The area is from about half-a-mile east of Sandsend to 

 Saltwick Nab. Some of the specimens have been submitted 

 to the Marine Biology Committee of the Y.N.U. If any reader 

 has a collection of named and located seaweeds from Robin 

 Hood's Bay, Whitby, or Sandsend, and would lend them to me 

 for a short time, I should be much obliged, as they might 

 harbour some species not in the list below. The collection 

 would of course be carefully treated and returned so soon as 

 possible, post paid.
