THE DISTRIBUTION OF HELIX {AOANTHINULA) 

 LAMELLATA JEFFR. 



H. A. SCHLESCH. 



It used to be thought that this species was to be found in Great 

 Britain only, but during the past few years it has been recorded 

 from North Germany, Denmark and Sweden. Its usual 

 habitat is in woods near the coast. As a British species it is 

 distinctly a northern form, becoming less common in the Mid- 

 lands, and rare in the South. It is found in the extreme North 

 of Scotland. 



In Ireland it occurs in the maritime counties on the north, 

 south, and west coasts, and in county Louth on the east coast. 



In Germany it is found in the northernmost parts on the 

 North Sea Coast and the shores of the Baltic as far as the mouth 

 of the Oder (Pommern) but has not been found in Mecklenburg. 

 It also occurs in Schleswig-Holstein, especially on the eastern 

 side. 



In Denmark it is recorded from Jutland, Funen, Zealand, 

 Lolland, Falster, Moen and Bornholm, but is scarce every- 

 where. Dr. C. A. Westerlund records the species from Sweden, 

 and it probably occurs in Holland. 



Marine Life at Saltburn. — During a week-end som- 

 little time ago, Mr. C. A. Cheetham and I spent a most intere 

 esting time at Saltburn studying the sea-shore life, more 

 particularly the zoophytes. Of these we found washed up 

 by the tide specimens of the following : — 



Thuiaria thuja, Antenniilaria antennina, Sertiilaria ciip- 

 ressina, Sertularia argentea, SerUilarella rugosa, on washed-up 

 Flustra joliacea ; Sertularia ahietina, Diphasia rosacea ; Calycella 

 syringa, occurring on S. argentea. 



Between tide marks we secured the following : — 



Sertularia pumila (common), Sertularia gracilis, Sertularia 

 operculata (common), Plumularia setacea on boulders between 

 Saltburn and Skinningrove ; Leptoscyphus tenuis, deep 

 pools on Laminarias ; Campamdaria flexuosa, deep pools 

 on Laminarias ; Sertularella polyzonias on Halidrys sili- 

 quosa, Tuhularia simplex, Staithes ; Coryne pusilla, Rock pools, 

 Staithes ; Clytia johnstonia, a fine colony on Corallina officinalis, 

 rock pools, Staithes. 



Between Saltburn and Skinningrove specimens of the 

 common nudibranchs {Archidoris tuierculata and Eolis papu- 

 losa) were found. — A. R. Sanderson, Bradford.
