Helix pisana, a European snail, became established in California and measures were taken to eradicate it. In Europe this snail is a pest of citrus trees. Observations at La Jolla, California, verified this. It is also a possible pest among other cultivated plants. The average number of eggs per individual at La Jolla in December 1922, was 120. This is higher than the number given for Europe. The methods employed in eradication were; clearing the ground of vegetation, flaming the cleared areas, use of poison bait of calcium arsenate and bran, and hand-picking. The results were effective and very few Helix pisana are left after one year of eradication work.
