As was to be expected, this list shows a close similarity 

 between the three districts. Mr. Shankland also investi- 

 gated and arranged the varieties of Helix nemoraJis on the 

 island. He found 14 distinct band-varieties, several of 

 them very rare ones, and he remarks in regard to this 

 species " I have never met with such a variety and richness 

 of colour." On August 19th and 20th Mr. Leicester and 

 Mr. Shankland were occupied in planting in appropriate 

 spots (all duly recorded in the journal at the laboratory) 

 batches of the following species, which ought to do w^ell 

 on the island, and which they had brought over in con- 

 siderable quantity from the mainland, viz.. Avion ater, 

 Avion hortensis, Avion suhfuscus, Avion houvguignati, 

 Limax flavus, Limax maximus, Amalia mavginata, Helix 

 aspevsa, Helix riifescens, CochUcopa tvidens, and Cary- 

 chiiun minimum. 



Faunistic Woek at Puffin. 



Our first visit in this year to Puffin Island was at the 

 end of February, when three members of the Committee 

 went down to the Biological Station for a few days, partly 

 for the purpose of collecting animals on the shore, and 

 partly to examine into the condition of the boats, the fresh 

 water cistern, the rain gutters on the roof, kc, and give 

 directions to the keeper.
