been found, but they have their nearest lithological analogues in the 

 latest pre-Cambrian and Cambrian series. Here are included some of 

 the most interesting rocks of Egypt, such as the Imperial Porphyry 

 and the Breccia Verde Antico. (b) The igneous member intruded into 

 these ancient sediments, etc., includes a great diversity of igneous 

 rocks, varying from highly basic to acid types. 



Contact-phenomena of complex nature occur at the junctions of 

 {a) and {h). 



4. Red granite and dyke rocks, whose parallelism and extent of 

 distribution present one of the most conspicuous features of the 

 Eastern Desert of Egypt, mark the final eruptive action before 

 Carboniferous times. 



5. Three periods of volcanic activity have been subsequently 

 noted — 



{a) In Western Sinai in late Carboniferous times. " 



{h) An undated series of eruptions interbedded with the base of 



the Nubian Sandstone or intrusive into it with marked 



contact alterations, 

 (c) The basic intrusions near Cairo and the Fayum, etc., 



which are intimately associated with the Oligocene 



Continental Period in Egypt. 



Y. — On the Phyllis Collection of Inferior- Oolite Eossils from; 



Doulting. 



By L. Richardson, F.R.S.E. 



rpHE Inferior Oolite and contiguous deposits of the neighbourhood. 

 J_ of Doulting have been described in detail in my paper on 

 "The Inferior Oolite and Contiguous Deposits of the Bath-Doulting 

 District" ;^ but since that paper appeared, through the courtesy of the 

 Urban District Council, I have had the loan of the John-Phyllis 

 Collection of Inferior-Oolite fossils that are housed in the Shepton- 

 Mallet Museum. 



This collection is probably only a portion of that made by Phyllis, 

 and although deficient in a number of specimens that are still to 

 be found in the neighbourhood, is a useful one, and contains a con- 

 siderable number that were not included in my lists. 



John Phyllis, of course, knew the localities whence his specimens 

 came, but — as is, unfortunately, so often the case — does not appear 

 to have been sufficiently particular about labelling them with their 

 localities. In a number of cases "near" Doulting must be under- 

 stood. At the time the collection was submitted for revision the 

 legends, in the majority of cases, read simply "L[ower] 0[olite], 

 Doulting." In a number of cases also it was certain that even this 

 information was erroneous. For example, a Schlotheimia of the 

 S.-angulata-Gxou-^, from the Lower Lias, was similarly strati- 

 graphically allocated and localized. However, a knowledge of the
