. Bulletin of the British Museum (Natural History), Geology. REVISION OF BECKMANN1A 11 Beckmannia from the late lower Givetian brachiopod assem- blages at Celechovice, Moravia, Czechoslovakia. Sapelnikov et al. (1987), while dealing with the Upper Silurian-Middle Devonian brachiopods of the eastern slope of the northern Urals, , described Beckmannia angularis (Phillips 1841) as possibly of Emsian age. If they are right in identify- ing their Urals specimens as Terebratula angularis Phillips, (1841: 89; pi. 35, figs 162a-c), then the British species must also be a record of Beckmannia.

If they are right in identify- ing their Urals specimens as Terebratula angularis Phillips, (1841: 89; pi. 35, figs 162a-c), then the British species must also be a record of Beckmannia. This revised occurrence of the uncinulid genus Beckmannia in Burma is from an assemblage of brachiopods generally considered as of Eifelian age (Reed 1908, Anderson et al. 1969). However, Anderson et al. (1969: 117), on admittedly somewhat inadequate evidence derived from the study of specimens of the conodont Polygnathus, suggested a correla- tion of the Burmese occurrences with the Upper Eifelian to Lower Givetian strata of central Europe. Mohanti & Gupta (1987) suggested the possibility of an Eifelian-Givetian boundary within the Padaukpin Middle Devonian strata. A Givetian age for the principal occurrences (Fig. 4) of Beck- mannia is favoured. Beckmannia is a rhynchonellid brachiopod having biogeo- graphical affinities with the Rhenish-Bohemian Region of the Old World Realm (Boucot 1975). Struve (1982a) favoured the terms Rhenish, Bohemo, Hercynian etc. as restricted to faunal provinces. Information from brachiopods indicates that the Rhenish-Bohemian Region of the Old World Realm extended from parts of the European marine depositional basins eastwards as far as Burma and China (Anderson et al. 1969, Zhang Yan 1985, Mohanti & Gupta 1987), while Struve (19826), working on data from well- known European regions, has provided a clear picture of the southeasterly extension of the Middle Devonian 'Rheno- Ardennic' brachiopod biogeography.
