short and up-to-date, and always bring out the most important 

 points. It is perhaps a pity to have left in the old and probably 

 )\iythical idea of the tropical condition of Greenland in Miocene 

 times. 



Tlie palseontological summaries are illustrated by many figures, 

 of which the new ones are of unusual clearness and softness. The 

 legends of the old blocks might have been further revised ; for 

 instance, the fossil numbered 3 on p. 339 is certainly not even 

 a member of the genus to which it is referred. It is possibly not 

 an oversight that has led the author to record a common Silurian 

 starfish as a Protaster, although it was made the type of a new genus 

 and family, Lapioorthura and Lapworthuridse. A misconception 

 regarding the Loudon Clay bird Odontopteryx may be noticed, as it 

 is widespread : the bird is described as " dentigerous or toothed " ; 

 the latter term is not absolutely incorrect, as it is not unusual to 

 speak of prominences on a beak as teeth, but " dentigerous " 

 certainly suggests that the bird had true teeth like the American 

 Odontornithes. But the errors of this sort are comparatively trivial, 

 and a certain number is inevitable in a book so full of information. 

 The new textbook may be confidently recommended to teachers for 

 the clearness of its statement of leading principles, the terseness of 

 its summaries of facts, and its graphic sketch of British geology.

L— December 21, 1898.— W. Whitaker, B.A., F.R.S., President, 



in the Chair. 



The President announced that Mr. F. W. Harmer, F.G.S., had 

 most generously offered to the Society the manuscript maps of the 

 Drift of the Eastern Counties made by the late Mr. Searles Wood, jun., 

 and by himself. The Council, in accepting the maps, had passed 

 a resolution specially thanking Mr. Harmer for the gift, and the 

 Fellows were now asked to add their thanks to those of the Council. 



The following communications were read : — 



1. " On a Megalosauroid Jaw from Ehsetic Beds near Bridgend, 

 Glamorganshire." By E. T. Newton, Esq., F.E.S., F.G.S. (Com- 

 municated by permission of the Director-General of H.M. Geological 

 Survey.) 



The specimen which forms the subject of the present communica- 

 tion was obtained from Mr. John David of Porthcawl, from a mason, 

 and it has been presented to the Museum of Practical Geology. It 

 was derived from beds low down in the Ehsetic Series, which may 

 eventually have to be included in the upper part of the Keuper. 

 The lamellibranchs on the same slab appear to he Fiiilnstra arenicola 

 and possibly Myophoria. The specimen has been compared with 

 reptilian jaws in the British Museum ; it consists of a mould of the
