The distribution of three genera of beetles of the family Carabidae has been cited by Jeannel as evidence of a Tertiary land bridge (Archatlantis) connecting the lands about the Mediterranean Sea with the West Indies. The beetles, however, do not really give evidence of such a land bridge. The three genera are all exceptionally minute and all seem to have crossed the Atlantic from east to west, the direction of both trade winds and hurricanes. These facts indicate that the beetles have not migrated over a land bridge but have been carried across the Atlantic by winds. The fact that two of the three genera have relatives on the remote Hawaiian Islands is a further indication that they are capable of dispersal by winds. Terrestrial vertebrates, the most significant of all animals where land bridges are concerned, show no sign of a bridge from the Old World to the West Indies, and there seems to be no geological evidence that such a bridge has existed. It is concluded that the three genera of Carabidae have been carried across the Atlantic by winds, that there was no Tertiary land bridge from the Old World to the West Indies, and that in this sense there was no Archatlantis.
