Abstract

Four new species of Calymenidae distinctive of horizons of strati-graphical interest are described. Observations of two pairs of anterior pits in the axial furrows of Platycalymene éire sp. nov. and P. duplicata (Murchison), not corresponding with the first lateral furrows of the glabella, indicate a trisegmental origin of the frontal lobe. A possible correspondence of the trilobite hypostome with chelicerae of Arachnids is propounded.
