•contribution to the fossil flora of the same district. The succession 

 of Carboniferous rociis, both Upper and Lower, is here very 

 perfect, ranging from the Calciferous Sandstone to the Upper Coal- 

 measures. The presence of true Upper Coal-measures in this 

 coalfield, with its characteristic flora, is especially remarkable. 

 This horizon has previously only been found in Britain in the three 

 Southern coalfields of South Wales, Somerset, and the Forest 

 of Dean. 



Mr. Kidston's paper also contains the most important contribution 

 to the Lower Carboniferous flora of Britain which has so far been 

 published. A large number of species are described from the 

 Calciferous Sandstone series, or its geological equivalents, of 

 Dumfries,, Cumberland, and Northumberland. Figures of several 

 of these plants are given, in addition to new species of Sigillaria, 

 Stigmaria, Pinalcodendron, and Falaostachya, and a new genus 

 Eskdalia from various horizons.

 New Genera of Batrachian Footprints of the Carboniferous 

 System in Eastern Canada. By G. F. Matthew, LL.D. 

 Canada Eec. Sci., vol. ix. No. 2, p. 99, 1903. 



fPHESE two articles are complementary. The first is a survey 

 X of the described Carboniferous and Devonian footprints of 

 America, with an attempt to classify them under generic heads. 

 It was found that diverse genera had been described under one 

 generic name, and that closely related tracks had been described 

 under different generic names by various authors. A table is given 

 to exemplify this ; in the table the genera are divided into related 

 groups, based on the number of toe-marks and the general aspect 

 <jf the footprint. The principal authors who have described these 

 tracks are King, Leidy, Lea, Butt, Marsh, and Dawson. The chief 

 places where these footprints have been found are the coalfields of 

 Eastern Pennsylvania, of Kansas, and of Nova Scotia. Some of the 

 types are common to several of these regions. 



In his second article Dr. Matthew gives figures and descriptions 

 of a number of new genera of Batrachian footprints from the Lower 

 Carboniferous and the Coal-measures of Nova Scotia. The smaller 

 forms are from the Joggins Coalfield, a larger one from the coalfield 

 of Sydney, Cape Breton, and another large one from the Lower 

 Carboniferous of Parrsboro', N.S. The figures show great diversity 

 of type, and justify the reference to different genera. 



The material described is mostly in the Redpath Museum of 

 McGill University, Montreal, and is a part of the large collections 

 made by the late Sir J. W. Dawson. Three plates of figures 

 accompany the first article and one the second.
