(After Eichwald.) This species forms thin, incrusting expansions upon EcTiinospherites in the Ordovician limestone at Pulkowa and at Wesenberg, the figured specimen being from the latter locality. Both the zooecia and mesopores, as indicated in figure 215, are an- gular, differing in that respect from A. lamella. I am unacquainted with an incrusting form of this sort from either Pulkowa or Wesenberg, but even were such specimens before me, more specific characters than are given by Eichwald would be necessary before an identification of any value could be made. ARCHEOPORA PUNCTATA Eichwald. Text fig. 216. Archeopora punctata Eichwald, Lethsea Rossica, vol. 1, 1860, , , fig. 19. The description of this species includes more details than that of any other of the various Ordovician forms referred to the genus, and it is possible that the new species, Favositella punctata, described in this volume, is based upon the same form. For this reason I have selected the same name for the supposed new species of Favositella and have indicated its possible identity with Archeopora punctata in the synonymy. Eichwald describes Archeopora punctata as a thin, rounded, lamellar expan- sion, with thick-walled, oval cells radiately arranged. One end of the cell is higher than the other [lunarium], and ten rows of cell
