Couutj-, N. Y'. Taconic. 



Conformitj' to the rules governing nomenclature, which are intended 



to render justice to every investigator, the genus Atops Emmous, 



1844, should replace that of Conocoryphe Corda described in 1847. 



The original figure of this species was the first primodial fossil 



described from American rocks; this species with 0/erie ^/m.s asaph- 



oides Emm. clearly defined the Taconic Sj'stem in 1844 and its 



position below Murchison's Lower Silurian of 1837. The fact 



that the original Cambrian was the same as the Lower Silurian 



cannot be recalled and in justice to Sedgwick it must be given to 



that system.
