 peculiar to Erere, and four genera, Productella, Strophodonta, Am-

As indicated in the foregoing pages, several of the Amazonian De- 

 vonian species are identical with North American Devonian. Begin- 

 ning with the lowest Pard beds, those of the Maecuru and Curud, we 

 find three species not occurring at Erere, which are the same as 

 North American species; they are Spirifera duodenaria (?), Amphigenia 

 elongaUi and Strophodonta perplana. Of these species two are known
