Favositella punctata is common at Uxnorm, Esthonia, in the Wassalem beds (D3). ARCHEOPORA RADIANS Eichwald. Text fig. 217. Archeopora radians Eichwald, Lethsea Rossica, vol. 1, 1860, p. 408, pi. 24, fig. 20. The figures of this species indicate without the shghtest doubt that it is founded upon the basal side of some parasitic bryozoan. As many forms would present the same or a quite similar appearance from this side, it is obviously impossible ^ ^ to recognize the particular one Eichwald figured. The species must, therefore, be classed as unrecognizable. Occurrence.—Ordovician limestone, near Pulkowa and Wesenberg, CALAMOPORA ALVEOLARIS Goldfuss. Calamopora alveolaris Gold- fuss, Petref. Germ., vol. 1, 1826, p. 77, pi. 26, fig. 1.— Eichwald, Letheea Rossica, vol. 1, 1860, p. Fig. 217.—Archeopora radians, a and b, the type- specimen, NATURAL SIZE AND ENLARGED. (AFTER Eichwald.) Russian specimens from various horizons and localities have been identified as above by Eichwald with this species, which, as figured by Goldfuss, is a typical Favosites. The Ordovician specimens so referred have certainly little in common with the latter form. CALAMOPORA FIBROSA Goldluss. Calamopora fibrosa var. tuberosa ramosa Goldfuss, Petref. Germ., vol. 1, 1826, p. 82, pi. 28, fig. 3. Calamopora fibrosa Eichwald, Lethsea Rossica, vol. 1, 1860, p. 469. Under this name Eichwald described one or more of the numerous massive Russian bryozoans, but which can not be determined. Gold- fuss's species is likewise so figured and described that it can not be recognized. Eichwald records the species from both Ordovician and Silurian localities of Baltic Russia. CALAMOPORA POLYMORPHA Goldfuss. Calamopora polymorpha Goldfuss, Petref. Germ., vol. 1, 1826, p. 79, pi. 27, figs. 2-5.—Eichwald, Lethsea Rossica, vol. 1, 1860, p. 466. The Ordovician specimen so iden
