Holotype.—Axial section (No. 3935, VNIGRI) from the Give- tian of Makarovskii raion, Russia (Poyarkov in Purkin et al., 1961, pl. 1, fig. 1).


Diagnosis.—Large species characterized by relatively numer- ous necks, irregularly arranged. Necks short to long with a broad central channel, and with proximal and distal enlargements. Wall relatively thin.


Occurrence.—Eifelian of the Tomsk area (SWSiberia) and the northen Urals. Givetian of Fergana, Tian Shan, Zeravshano- Gissar, SW Siberia, the central Urals, Germany, western and northern France, and ?Moravia. Givetian of Mount Polinik (Carnic Alps, Austria).


Description.—Outer diameter=0.23–0.60mm (type material: 0.28–0.47mm); inner diameter=0.16–0.55mm; number of necks: 13–16; length of necks=0.07–0.13mm (with a wall of 0.015–0.045mm); test wall thickness=0.013–0.016mm (type material: 0.012–0.03mm).

Materials.—10 specimens (samples POL11b-5, POL11b-19, POL13a-5, POL13a-6, and POL13a-8).


Remarks.—Givetian and Frasnian Parathurammina specimens assigned to P. dagmarae more probably belong to Bykovaella bykovae, whereas true P. dagmarae only appear in the Famen- nian (Poyarkov, 1969, 1979).

2013 Parathurammina macilenta; Sabirov, text-fig. 1.


Holotype.—Axial section (No. 2/1060; Museum of the Geolo- gical Direction of the Urals, UTGU) from the Givetian of the northern Urals, Russia (Pronina, 1970, pl. 30, fig. 5).


Diagnosis.—Very large species characterized by relatively numerous papillae, short and irregularly arranged. Wall thin.


Occurrence.—Givetian of the central Urals and western France. Givetian of Mount Polinik (Carnic Alps, Austria).


Description.—Outer diameter=0.45–0.70mm (type material: 0.50–0.95 mm); inner diameter=0.36–0.65mm, number of papillae: 8–14; tests wall thickness=0.006–0.012mm (type material: 0.015–0.022 mm).


Remarks.—Bykovaella turgida (Chuvashov, 1965), poorly known, probably belongs to the same group of species.


Materials.—Three specimens (samples POL14-20 and POL14-21).


Genus Kolongella Zadorozhnyi in Zadorozhnyi and Yuferev, 1984


Type species.—Parathurammina kolongensis Pronina, 1969. Other species.—See Zadorozhnyi and Yuferev (1984).


Diagnosis.—Test unilocular. Central chamber spherical. Infundibuliform, radiate necks, prominent at the periphery and not communicating with the central chamber. Apertures at the extremities of the necks. Wall dark-microgranular.


Occurrence.—Late Silurian–Middle Devonian, eastern slope of the Urals and southwestern Siberia. Late Eifelian of Belgium. Givetian of El Bisani sections (Sonora, Mexico; D.V. unpub- lished data).Discovered in the early Givetian of the Carnic Alps.
