(1). Loioer or Quebec Group of Logan. 



(2). Middle Division, or Trenton and Black River Roclcs of Hall and 



Logan. 

 (3). Upper Division, or ITudson River and Lorraine Rocks of Sail 



and Logan (apparently wanting). 



The lithological characters of these groups are described with 

 much minuteness, and their stratigraphical relations discussed. Into 

 these details our space forbids us to enter, but we cannot refrain 

 from quoting from the paragraph in which Professor Lapworth con- 

 cludes this interesting and suggestiTe study of Canadian Graptolites. 



" In the careful study of the geographical and geological distribu- 

 tion of the several horizons of these Graptolites in the extensive 

 convoluted rock series of the Eastern Townships, lies the solution 

 of the great geological enigma of the Quebec Group and its puzzling 

 associates. We shall not be able to parallel the eastern and western 

 series, formation for formation, until we know more of the Grapto- 

 litic fauna of the Chazy, Black Eiver, Trenton, Utica and Lorraine 

 formations themselves, where they lie flat and undisturbed, and can 

 compare them with those of their European equivalents. This is 

 a work that ought to be at once taken up by American geologists, 

 and carried on, stage by stage, with the study of the equivalent 

 rocks of the convoluted eastern areas. Till this is done, all our 

 correlations of these eastern deposits must be regarded simply as 

 provisional approximations, liable to inevitable modification and 

 improvement in the light of future discovery." 



The last few pages of the Report are devoted to a " Provisional 

 list of Fossils [^.e. Graptolites], with localities," together with two 

 useful tables ; Table A. " Showing the various Horizons, approximate 

 Geological Age, and American and European Equivalents of the 

 several Graptolitic Zones," etc. Table B. " Showing Vertical Range 

 of Graptolites from Rocks between Cape Rosier (Gaspe) and Cap 

 Rouge (Quebec)." A. H. F.

I. — The Pal^eontographical Society of London. 

 Report of the Council read and adopted at the Annual 

 General Meeting, held at the Apartments of the Geo- 

 logical Society, Burlington House, 17th June, 1887, Dr. 

 Henry Woodward, F.R.S., Vice-President, in the Chair. 



IHE Council in presenting their fortieth Annual Report take the 

 JL. opportunity of inviting the attention of Members to the publi- 

 cations of the Society and to the faithful manner in which the 

 wishes and purpose of its founders are being carried into effect. 



Since the last meeting was called, a volume has been issued — one 

 every way equal to its predecessors, so far as the valuable scientific 

 information contained in it and the beauty of its illustrations are con- 

 cerned. This book (the return for the Members' subscriptions due 

 in 1886) contains five distinct subjects, four of which form the 

 commencement of new monographs, and one is the continuation of
