Clausilia (272 sp.) is most abundant in Europe, with a few
species widely scattered in India, Malaya, China, Japan, Equa-
torial America, and one in Porto Eico. The described species
have been increased to nearly 500.
Bulimulus (210 sp.) is American, and almost exclusively
Neotropical, ranging from Montevideo and Chili, to the West
Indian Islands, California and Texas ; with two sub-genera con-
fined to the Galapagos Islands. About 100 new species have
been described since the issue of the second edition of Dr.

regions, but has a very wide range, being scattered throughout
Africa, continental India, Australia, the Pacific Islands, North
America to Greenland, and the Antilles; but it is absent
from South America, the Himalayan and Malayan sub-regions,
China and Japan. An extinct species has occurred abundantly in
the carboniferous strata of North America. About 160 addi-
