Extract

Of the abounding Trilobites which mark the faunas of the Lower and Middle Palæozoic rocks few survive into the Upper Palæozoic. Three genera, if indeed they really deserve that name, have been described from the Carboniferous beds in England—Phillipsia, Griffithides and Brachymetopus. Only the first of these is yet known to occur in American Palæozoic strata. But on the other hand two species of Proetus have been announced from America—a genus not yet recognized in England. It is true that the distinctions are so slight that possibly these last might be as correctly referred to Phillipsia as to Proetus.
