Abstract
Land snails of the genus Partula, inhabiting the high islands of the Pacific Ocean, have provided exceptional opportunities for studies oil the origin and differentiation of species: The endemic taxa of Moorea, in French Polynesia, have been particularly well studied. In an attempt to control the numbers of the giant African snail, Achatina fulica, which is an agricultural pest, a carnivorous snail, Euglandina rosea; has been introduced into Moorea. It is spreading across the island at the rate of about 1.2 km per year, eliminating the endemic Partula. One species is already extinct in the wild ; and extrapolating the rate of spread of Ezigltmdina , it is expected that all the remaining taxa (possibly excepting P. exigua) will be eliminated by 1986-1987. Euglandina has been introduced into many other oceanic . islands, and it appears that more than a hundred endemic species are at risk . These observations point to a serious danger in programs of " biological control. "
