Vol. 58.] ASSOCIATED BEDS OF THE MALVERN HILLS. 107 
Salt., have been obtained. The thickness of the Coal-Hill Band in 
the southern part of the district is about 250 feet, the shales alone 
being perhaps 100 feet thick. 
The Upper Grey Shales are well exposed in two spots: namely, 
in the bed of the stream, south of Bronsil (M159), and at the south- 
eastern corner of Chase-End Hill (M275). In the first-mentioned 
locality the only fossil obtained was the rib of a trilobite; the 
Chase-End exposure yielded a specimen containing an Asaphid tri- 
lobite (pygidium and part of thorax) agreeing, so far as can be seen, 
with Platypeltis Croftii, Call., together with what seems to be a 
portion of the head of Parabolinella (?) triarthrus, Call.; but Dictyo- 
nema sociale, Salt., is the most abundant fossil. ‘This small section 
has long been known as a locality for Dictyonema, which was first 
discovered here by Symonds. The thickness of the Upper Grey 
Shales in the southern part of the district may be estimated at 
about 500 feet. 7 
Shales probably belonging to this horizon were revealed in 
excavations made by me, on either side of the path half way 
between Fowlet Farm and Martins; and others are sometimes 
imperfectly exposed in the ditch along the main road, close to 
Bronsil Lodge. Loose fragments obtained close to Martins 
(M156) yielded in abundance Lingulella Nicholson, Call., and 
Acrotreta Sabrine, Call.; and grey shales (M155) from the road- 
side due north of Fowlet Farm yielded a fine specimen of Obolella(?) 
Salteri. 
Besides the fossils recorded above from the Bronsil Shales, addi- 
tional species have been obtained by the prolonged researches of 
Grindrod and others, and are to be seen in the Museums at Oxford, 
Jermyn Street (London), Malvern, and Worcester. In the Grindrod 
Collection at Oxford a number of specimens are preserved, which 
(as | am informed by the present Dr. Grindrod) were obtained from 
the well-known small exposure of Dictyonema-shales at Chase-Knd 
Hill (M 275),’ to which allusion has just been made. ‘These include 
some fragments of Asaphids, probably referable to Platypelts 
Croft, Call.’ (fig. 29, p. 122), Miobe Homfrayi, Salt. (fig. 31, 
p. 125), and Asaphellus affinis, McCoy (or A. Homfrayi, Salter), 
Acanthopleurella Grindrodi, Groom’; an Olenid, probably referable 
to Olenus (Parabolinella?) triarthrus, Call. ; Langula (?) sp. (fig. 9, 
p- 142); and Acrotreta sp. cf. A. Nicholsons (fig. 10, p. 142). A 
specimen of dark shale labelled ‘ Malvern, and probably collected 
from the Bronsil Shales, contains Mode (?) sp., near ‘ Oqgygra’ peltata 
(fig. 30, p. 123). In dark-grey, minutely micaceous pieces of shale
