SILUEIA. 
[Chap. V. 
The next deposit met with in ascending order in the line of the above 
section, npon the west flank of the Malverns, consists of grits, conglome- 
rates, and sandstones, occupying, as before said, a thickness of 600 feet, 
the chief localities being Howler's Heath, Cowley Park, the west of Here- 
ford Beacon, the Wych, &c. The forms usually characteristic of this band 
of the Upper Llandovery rocks are the Pentameri before noted, Atrypa 
hemisphgerica, Rhynchonella decemplicata, together with some of the Uni- 
valve Shells and Corals previously mentioned as occurring at Llandovery. 
Of the latter, the Petraia subduplicata, M'Coy, is abundant ; and Orthis 
calligramma is not unfrequent. The zone is here specially characterized by 
a number of bivalve Nucula-like shells ; of which Ctenodonta Eastnori and 
Ct. subaequalis (PI. X. f. 7, 8) are examples. The last-mentioned species 
and its associates, Bellerophon trilobatus and Holopella obsoleta (PI. IX. 
f. 28), pass upwards, as will be seen in the sequel, to the uppermost 
Ludlow rock. 
One of the shells highly characteristic of the Upper Llandovery rocks in 
this district is the Lingula crumena, Phill., which was figured by mistake 
amongst the fossils of the Caradoc formation, < Siluria,' 1st edition, p. 86 
(Eoss. 7. f. 5) : see above, p. 68 (Eoss. 13. f. 5). Even the peculiar Crusta- 
cean, Pterygotus, which, as we shall presently see, is eminently an uppermost 
Silurian form, has its representative here, in fragments which were found 
south of Eastnor Obelisk by Mr. John Burrow, of Malvern. 
It is also worthy of notice that a 
perfect cast of a Eucoid was found in a 
fragment of this rock on the west side 
of the North Hill by the well-known and 
zealous botanist Mr. Edwin Lees ; and 
as vegetable remains are rarely found 
in these deposits, the specimen is here 
figured*. 
These Upper Llandovery rocks, in the 
form of a dingy purple grit with a super- 
jacent flaggy limestone, range from the 
End Hill of Malvern to Old Storridge Hill, 
and are seen for the last time in Ankerdine Hill, the most southern of the 
Abberley Hills. Throughout its course along the west flank of the Malverns, 
where it rests upon the eruptive rocks f, and thence to the gorge of the
