Ll. Inrropvuction, 
Iy a former communication ' the disposition of the older Paleozoic 
beds in the Southern Malverns was described, but few strati- 
graphical details were given. It is proposed on the present occasion 
to complete the description of these rocks, with the exception of the 
lithology. Further research has strengthened the conclusions 
formerly drawn, and has afforded some additional evidence as to the 
succession ; while diligent collecting, and examination of the spe- 
cimens previously collected, has added many fossils to the small stock 
hitherto known. A number of these are new; they have already 
been described in part by Mr. Frederick Chapman,’ and by the 
author,’ and descriptions of the remainder by Mr. C. A. Matley 
and the present writer will be found towards, or at the close of this 
paper, together with some notes on certain trilobites for which 
Mr. Philip Lake and myself are jointly responsible. 
The following subdivisions of the strata may now be recognized :— 
4. Bronsil Shales (Grey Shales). 
White-Leaved-Oak Shales (Black Shales). 
2. Hollybush Sandstone. 
1. Malvern Quartzite.*

[This name is intended to replace that of Hollybush Quartzite and 
Conglomerate used in my first memoir on the district. The change has 
been made in accordance with a suggestion put forward by Prof. Lapworth at 
the reading of the paper.—December 5th, 1901.]
