Tertiary and Triassic Gastropoda of the Tyrol1

Abstract

THOUGH much has already been done for continental palæontology, a great deal still remains to be accomplished. The earlier workers in the field laboured under the disadvantage of having to deal with comparatively scanty material, mostly scattered in private collections over large areas at a time when intercommunication was far from easy. Nowadays these old collections with their type-specimens have for the most part found their way into the museums of the principal cities. Moreover, not only may they freely be examined on the spot, but sometimes, we are glad to know, are allowed, under proper precautions, to be removed for the purpose of comparison with types preserved elsewhere. These altered circumstances and the acquisition of new specimens have not merely aided, but even provoked the revision, rectification, and completion of the labours of bygone times.
