(7) The Upper Toarcian (moorei-dumortierice hemerse) makes a 

 great showing at Burton Bradstock and Down Cliffs as the Down 

 Cliffs Clay and Bridport Sands (pars) — -the greatest thickness of 

 rocks of these dates in the country. 



(8) The sequence of aalensis-strata ahove moorei-beds is demon- 

 strated at Chideock Quarry Hill, in the upper part of the Bridport 

 Sands. 



(9) The Inferior Oolite (Aalenian, Bajocian, Bathouian pars) 

 strata of Burton and Chideock are not counterparts of one another : 

 they supplement each other to a certain extent ; both are in- 

 complete, and much epitomized representatives of thicker deposits 

 elsewhere. 



(10) Mr. Thompson's zonal scheme for the Upper Lias is 

 considered, and a table of Upper Lias zones for future work is 

 presented. 



2. ' Certain Jurassic (" Inferior Oolite ") Ammonites and Braehio- 

 poda.' By S. S. Buckman, E.G.S. 



This paper is presented as a palaeontological appendix, partly to 

 the Author's accompanying communication, partly to his previous 

 stratigraphical work. In a short introduction the Author, remark- 

 ing on the fecundity of the 'Inferior Oolite' in the matter of 

 species, makes the suggestion that this is due to the relatively 

 great length of time taken up in its deposition ; and he adduces 

 data for supposing that the time thus occupied was from one-fifth to 

 one-fourth of that for the whole Jurassic System. 



The paper describes certain species of Ammonites and Brachiopoda 

 which are important for the identification, the correlation, or the 

 dating of Inferior Oolite deposits, and certain other notable species 

 which, having frequently attracted attention in the field, require 

 naming in the interest of future workers. 



3. ' The Cretaceous and Eocene Strata of Egypt.' By William 

 Eraser Hume, D.Sc, A.R.S.M., E.G.S., Superintendent, Geological 

 Survey of Egypt. 



The Author divides the fossiliferous Cretaceous strata into three 

 series : — 



1. A northern Antonian type, marked by Cenomanian species, 

 including typical Turonian strata. 



2. A central Egyptian or Hammama type, Cenomanian strata 

 being absent, Campanian marked by abundance of Ostrea villei and 

 Trigonarca multidentata, and phosphatic beds ; the Danian portion 

 having an eastern facies in which Pecten-va&Tls are a characteristic 

 feature, and a western chalky limestone indicating a close affinity 

 with the white chalk of Northern Europe. 



3. A southern or Dungul type, having close affinities with 2, but 

 in the Campauian the phosphatic beds are inconspicuous, and the
