I. — Prof. W. Dames on a Swedish Cretaceous Bird, 

 "Ueber Vogelreste aus DEM Saltholmskalk von Limhamn bei 

 Malmo." By W. Dames. Bihang till k. Svenska Vet.-Akad. 

 Handl., vol. xvi. pt. iv. No. 1, with plate (1890). 



IN this paper Professoi* Dames discusses associated right humerus, 

 coracoid, and scapula, apparently of a bird, obtained by 

 Professor Lundgren from the Upper Senonian of Southern Sweden. 

 In the course of his introductory remarks he alludes to the possible 

 occurrence of a gadoid fish in the same formation — the determina- 

 tion being apparently based upon the original example of Dercetis 

 limhamnensis of Davis. A detailed description of the bird-bones 

 follows, and the provisional name of Scaniornis Limdgreni is pro- 

 posed for the genus and species they represent. All known carinate 

 birds from the American and European Cretaceous and Tertiaries 

 ai'B successively I'eviewed in comparison ; and a reference to recent 

 skeletons suggests that the new extinct Swedish type is a primitive 

 wader. A. S. W. 



II. — The Geology of the Long Mountain, on the Welsh 

 Borders. By W. W. Watts, M.A., F.G.S.^ 



THE author described the Silurian succession in a part of West 

 Shropshire and East Montgomeryshire. 



1. May Hill grit, sometimes conglomeratic, containing one richly 

 fossiliferous band of limestone at Cefn, Buttington, This is traced 

 from Cefn to the north end of the Breidden Hills, where it appears 

 to thin out. It rests unconformably on various members of the Bala 

 group, and at Cefn a small dyke of diabase is intruded along the 

 junction line. 



2. Purple and green shales with very rare fossils, chiefly Ento- 

 mostraca and small Brachiopods. 



3. Wenlock mudstones, earthy in the lower part, and more cal- 

 careous above, containing Cyrtograptus Linnarssoni, Monograptus 

 Flemingii, M. duhius, and M. serra. These beds appear to rei3resent 

 the upper part of the Wenlock shale and the Wenlock limestone. 



4. Thin muddy shales with rai'e flaggy ribs, containing Mono- 

 graptus colomis, M. Nilssoni, and Cardiola interrupta ; these are the 

 equivalent of the Lower Ludlow beds. 



5. Hard thick flags, with occasional shales. Monograptus Leint- 

 loardinensis, M. Salweyi, M. Boemeri, the equivalent of the Aymestry 

 limestone. 



6. Thin fissile shales almost barren, but with Cardiola. These 

 occupy the place of the Upper Ludlow Eocks. Above these beds 

 comes an outlier of the Passage-beds with Lingula and Entomostraca. 



The structure of the range is a large syncline with a steep dip on 

 the north-west side, but this is complicated by several dip- and 

 strike-faults and one or two small synclines. 



The author acknowledged the great help rendered by Professor 

 Lapworth in determining the Graptolites.
