THE GEOLOGIST. 
There is not in all England more lovely scenery than that 
around the protruded Upper Silurian dome of Hagley Park, in 
the village of Bai-testree, five miles S.E. of the old town of 
Hereford, nor am I aware of any locality where the Ludlow bone 
bed is more charged with the relics of dead fish and Crustaceans. 
It was here that my late friend, Mr. Scobie, obtained the most 
perfect claw of the "Pterygotus Problematicus," — that extuict 
SUuriau lobster, — yet known to science ; here Mr. Strickland found 
the seeds of the first known land plant, a Lycopodium, or fossil 
club-moss ; and the only time I could ever afford an hour's work 
there, I obtained the finest spine of the Onchus Murchisoni, an 
Upper Silurian plaeoid fish, I have ever yet beheld ; while, 
doubtless, the cabinets of the Geologists of Herefordshire are 
enriched vrith numerous specimens I have not seen. The 
members of the Woolhope Club can hardly allow so rich a bed 
to remain imexplored, more especially when the comleous owner 
of the land, Mr. Phillips, railed off the dome, and preserved it for 
their peculiar examination and benefit. 
To return to the organisms of the bone bed ; it is a curious fact 
that, a few months after Mr. Strickland and Mr. Salter had 
described the Pterygotus of the Hagley dome, Mr. John Burrow 
should find the jaw-foot of the same animal in beds immensely 
lower in the Geologic scale, even in the Caradoc sandstones below 
Eastnor obelisk, on the flanks of the Malvems. Thus we have 
evidence that this Crustacean, or one of the same genus, lived in 
the Caradoc Ocean. Nor is this all ; the Pteiygoti are found in 
strata far higher than the Upper Ludlow bone bed ; they swarm in 
the Tilestones of the Kington district, where it was discovered by 
Mr. Banks. It is there associated with its feUow-Crustaceans, 
Pterygotus Anglicanus and Himantopterus, with the Silurian fish, 
Onchus Murchisoni, the new forms of, Plectrodus, Cephalaspis 
omatus, Auchenaspis Salteri, and last, though not least, with the 
Upper Silurian fossil, the little moUusc, Lingula cornea. We 
ascend considerably higher on the ladder of geologic history, and 
near Kidderminster we find gi'ey tilestones passing upwards into 
true Comstones; here Mr. Roberts detected the Pterygotus and 
Eurypterus buried in the same grave with those very charac- 
teristic Old Red fishes Cephalasj)is Lyellii, and Cephalaspis
