Hall made the change of genus on account of certain differences between the European and American species. H. S. Williams who has studied this shell from New York, Eng- land, Belgium, France, Germany, Russia, Siberia, Persia and China, says that it has not been recognized in the interior of N. America, Meek's R. oastenea from Nevada and McKenzie's river being only an ally of it; and that if a Guboides zone be adopted for its world-area "it may be said that a considerable number of species (including forms, under different names, which are very closely allied modifications of the same races) appeared before the 'Guboides Stage' in the English, European and Russian sections, but not till after that stage in the New York section.'- (Amer.
