Thus, as a rule, the commoner Mecuru species are not found at 
Ereré, or are poorly represented there; and the same is true of the 
commoner Ereré forms on the Mecurt. The genus Cyrtina (?) is 
peculiar to Ereré, and four genera, Productella, Strophodonta, Am- 
bocelia (?) and Amphigenia are only found on the Mecurt. 
As indicated in the foregoing pages, several of the Amazonian De- 
vonian species are identical with North American Devonian. Begin- 
ning with the lowest Para beds, those of the Mecuru and Curud, we 
find three species not occurring at Ereré, which are the same as 
North American species; they are Spirifera duodenaria (?), Amphigenia 
elongata and Strophodonta perplana. Of these species two are known
