 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. Jour. Sci. Jan., 1890. On the Devonian Sys-
