Vol. 56.] STKUCTUEE OF THE MALVEEN AND ABBEELEY HILLS. 149 



The junction of the May Hill Sandstone with the Archaean 

 massif is evidently a thrust-plane, as I have endeavoured to show 

 in a previous communication. 1 The tunnel-section is reproduced in 

 fig. 5, below. Elsewhere between the Herefordshire Beacon and the 

 Wyche there is no evidence to show the nature of the fault.

An interesting feature aboat the Wyche Pass is the occurrence of 

 a patch of May Hill Sandstone close to the western opening of the 

 cutting. According to Phillips, this is embedded in the crystalline 

 rocks. The sandstone, I am informed by Mr. Wickham, of Colwall, 

 was lately revealed in excavations made by the Malvern Field 

 Naturalists' Club. A figure is given 2 by Phillips, showing the beds 

 almost vertical (inverted at the top) ; they belong to the upper part 

 of the May Hill Series, and a list of fossils tabulated by Phillips 

 includes the following : — StricMandinia lens, Atrypa reticularis, 

 Orihis testudinaria, Bhynchonella decemplicata, Spirifera crispa, 

 Pleurotomariajissicarina, Euomplialus corndensis, Favosites, ' Petraia,' 

 etc. This patch is apparently of the same nature as those already 

 described in the liaggedstone and Midsummer Hills, 3 and as those 

 which will be described on a subsequent page in speaking of North 

 Hill (p. 152). 



VII. The Worcestershire Beacon and North Hill. 



The fine elevations of the Worcestershire Beacon and North Hill 

 together form one of the most conspicuous and characteristic por- 

 tions of the Malvern Range. As in the middle portion of the Range, 

 the Archsean massif is bounded on the west by May Hill Beds ; but, 

 whereas along most of the Range the May Hill Beds in contact 

 with the Archaean belong to the upper, light-coloured part of the
