98 PROF. GROOM ON THE CAMBRIAN AND | Feb. 1902, 
greyish-white quartzite (Malvern Quartzite). Fossils: Kutorgina 
Phillipsii, Linnarssonia sagittalis, Obolella (2) Saltert,: Hyolithus 
sp., and Scolecoderma antiquissima. Fossils in the white quartzite : 
Oboiclla (?) Groomii and Kutorgina Phillipsii (2). Thickness not 
less than 75 feet. 
(6) Paleontology. 
The fossils recorded from the Hollybush Sandstone by Holl ? 
are the following :—Scolithus, Scolecoderma (Trachyderma) anti- 
quissima, Serpulites fistula, Lingula squamosa, Lingula sp., Kutorgina 
(Obolella ) Phillipsit, Obolella 2 spp., anda small bivalve. Murchison* 
records also the following :—Lituites sp., Theca sp., Obolella Salteri, 
and annelid-tubes. It is unfortunate that scarcely any of the fore- 
going specimens appear to have found their way into the large public 
collections. The only fossils from the Hollybush Sandstone that I 
have been able to find in these collections are Hyolithus (Serpulites) 
fistula and Scolecoderma (Trachyderma) antiquissima. 
It appears very doubtful whether many of the specimens recorded 
were obtained from the Sandstone (see p. 93), and the generic 
value of most of the unnamed species is very uncertain. The only 
forms which it seems safe to refer to the Hollybush Sandstone are 
the following :— 
Kutorgina cinaqulata, var. Phillipsii Hyolithus, 2 or more spp. 
(Holl), Modiolopsis (2) sp. 
Hyolithus (Orthotheca) fistula(Holl). | Scolecoderma antiquissima (Salter). 
H. primevus, sp. nov. | Casts of foraminifera. — 
A malvernensis, sp. nov. | 
IV. Tas Woarre-Leavep-Oak SHALES. 
(a) Palzeontology and Thickness. 
The Malvern Black Shales appear to have been first detected by 
Conybeare.’ They were subsequently recognized by Murchison, and 
doubtfully correlated by him with the Llandeilo Beds.’ A year or 
two later John Phillips’ detected Agnostus and other trilobites in 
the shales, a discovery which induced Barrande to place the shales 
on the horizon of the Lingula-Flags and of his ‘ primordial fauna.’® 
The further discovery by Symonds of Dictyonema sociale, Salter, in the 
immediately overlying Grey Shales tended to confirm the antiquity 
1 The specimens of Linnarssonia sagittalis and Obolella (?) Salteri, recorded 
from the Hollybush Sandstone, have not undergone revision by Mr. Matley.

4 Mr. Frederick Chapman has carefully examined the glauconitic casts of 
foraminifera in the Malyern Quartzite and Hollybush Sandstone, and in the 
grits of the White-Leaved-Oak Shales, but has failed to identify any of the 
enera.
