to the more ornate forms with more complex suture-lines, as is 

 well shown in the Prolecaniticla9, by such genera as Medlicottia, 

 Sandbergeroceras, Gnstrioceras, etc. 



The aptychi of Goniatites from the Upper Devonian, near Her- 

 born, Nassau, are described and figured. There are, indeed, no 

 fewer than 145 illustrations in the text, some of which are of very 

 beautiful forms, as Gnstrioceras Jossa (tig. 109) ; Ghjphioceras Eispani- 

 crim (fig. 91); G . fimhriatum ; Fericychis Doohylensis ; P. princeps 

 (fig. 68) ; Prolecanites compressus (fig. 116) ; Agathiceras Suessii 

 (fig. 130). 



The Introduction furnishes a useful summary of the Bibliogi'aphy 

 of the Goniatites and their allies, of which Group A is chiefly 

 composed. 



The Triassic Ammonites, on which Mojsisovics has laboured so 

 long and so successfully, will probably fill Part IV ; this we hope 

 will shortly follow the present volume. Beyond these lie the 

 Ammonites of the Jurassic and Cretaceous formations, and the hosts 

 of the Belemnites, the Squids, and Cuttles ! We can only con- 

 gratulate the authors and wish them " more power " ; we may 

 even venture to suggest that they may find it needful to take more 

 hands aboard and hoist more sail, or the " Argonaut " will never 

 reach her port.

1. " On the Gravels and associated Deposits at Newbury (Berks)." 

 By E. Percy Richards, Esq., F.G.S. 



After a general sketch of the geology of the Valley of the Kennet, 

 the superficial deposits at and in the neighbourhood of Newbury 

 are described in detail, from observations made by the author during 

 the progress of the main drainage works in 1894. 



The author classifies the strata which he has examined in five 

 groups — 



(1) The Preglacial Southern Drift. 



(2) The Glacial Drift (Donnington). 



(3) The Upper River-gravel. 



(4) The Lower River-gravel. 



(5) The Neolithic peat-beds (shell-marl, peat, and loam). 



(1) The first of this series is the flint-gravel constituting the 

 heathy Commons north and south of Newbury (as of Snelsmore and 

 Greenham). About 6 feet of gravel is exposed at the average 

 level of 440 feet above Ordnance datum. It was referred to the 

 "Southern Drift" by the late Sir Joseph Prestwich. At the edges 

 of the Commons some of this gravel slips down and mixes with 

 glacial deposits of later age.
