prominent part of which it forms, and is last seen east of Hill 

 Farm. It is overlain by a not very thick series of purple and 

 greenish sandstones and conglomerates, with grey sandstones in the 

 upper part. These conglomerates sometimes abound in fossils ; they 

 constitute the beds known as ' Miss Phillips's Conglomerate/ and 

 form a useful horizon in the series. They may be traced from 

 Rough Hill, through Cowleigh Park, and have long been known in 

 the southern part of West Malvern, where they come into direct 

 contact with tbe Archaean. Traces of the purple-and-green rock 

 may be seen still farther south. Mr. H. D. Acland informs me 

 that he has found fragments at Hillside ; while Symonds l speaks of 

 alternating purple and grey beds at Wychcrest, records StricHan- 

 dinia from this spot, and terms the beds containing this fossil the 

 6 Stricklandinia-hQdLs' Allusion has also been made to the purple 

 beds near Wind's Point (p. 146). I have not succeeded in con- 

 vincing myself that these ' StricMandinia-\)e<ls' form a definite 

 horizon, for I have found the fossil both in the lower and upper por- 

 tion of the purple beds, and in the passage-beds between these and 

 the overlying grey series, and Mr. Wickham informs me that it occurs 

 high up in the latter beds, a short distance below the Woolhope 

 Limestone. Stricklandinia is, however, perhaps, most abundant in 

 the upper part of the purple beds, and in the passage-beds between 

 these and the grey series. The Archaean rocks along much of the 

 Malvern Range appear to be frequently in contact with the beds of 

 this horizon. 



In Cowleigh Park the May Hill Beds and Woolhope Limestone 

 •ire both inverted. 



Of considerable interest is the occurrence in this district of small 

 patches of Archaean rock, associated in one case with Cambrian 

 tjuartzite. These were observed and correctly mapped by Phillips, 2 

 but in Holl's map 3 one of them is incorrectly represented as ex- 

 tending as far north as the boundary of the Trias. 



On p. 37 of Phillips's memoir, a section across the southernmost 

 of these patches is given. The brown May Hill Sandstones imme- 

 diately to the west were in 1848 evidently much better exposed than 

 at present, and are stated to have generally a dip of 80° or more, 

 but close to the ' syenite' to be somewhat inverted. The ' reddened 

 drift ' drawn in the depression of the ' syenite,' which Phillips was 

 disposed to regard as Haffield Breccia (' Permian '), is, I feel sure, 

 nothing more than debris from the adjacent purple May Hill Grits : 

 it contains no traces of the pebbles which are characteristic of the 

 Breccia. 



The two northern exposures of Archaean rock occur in a line with 

 that just described, and the long axis of each mass follows the same 

 line. There can be little doubt that this is a line of dislocation, 

 as, indeed, Holl represents it in his map (op. jam cit.) ; but the fault
