LAND MOnLLUSCA. 
In several previous reports Mr. A. Leicester’s work on 
the Land Mollusca at Puffin Island has been alluded to. 
During the last year he has made two special expeditions 
to the island, and has been indefatigable in his search, 
exploring the bushes, tufts of grass, and rock crannies 
high and low from unconscionably early hours before 
breakfast till dark night, and leaving literally not a stone 
unturned in his track. He is now supported in his labours 
bythe Rey. T. Shankland, formerly of the University College 
of Bangor, now at Mold, who made three or four trips to 
Puffin Island during July and August for the purpose of 
comparing the molluscan fauna with that of Anglesey and 
North Wales, and for the purpose of introducing certain 
species not found on the island. Altogether they have 
found during the year 22 species of land Mollusca on 
Puffin Island, of which 5 are new records (including 
Amalia marginata, A. gagates, and Vertigo pygmea). 
Mr. Shankland has drawn up comparative lists show- 
ing which of the British genera of Pulmonata have been 
found (1) at Putin Island, (2) on Penmon Point, Anglesey, 
and (3) on the Great Ormes Head, as follows :--
