THE GEOLOGIST. 
New Fossils from Skiddaw Slates.-Sir,--I think it is worth while to caU 
the attention of your readers to a new and very interesting locality for fossils- 
ill the celebrated Skiddaw slates. Mr. Bryce TV' right, of 
Kussell-street, who is well known in the natural history 
trade, devotes some time annually to collecting them: and 
he has a store on hand, from the neighbourhood of Keswick, 
New Onstacean from the Graj)tolites sacjittarius, G.latus, G. tenuis; also a new 
Skiddaw-siates. Crustacean form allied to Bithyrocaris, very abundant. 
Lastlv he has discovered— and we owe him many thanks for doing so— the 
brauclicd'Graptolites (wliich Sir W. E. Logan first brought to H£:ht in Canada), 
of this shape. 
Prof. J. Hall considers them only to belong to the genus Graptolites, which 
has a simple stem with one row of cells. 
r. ^fr„„'^,y.'r,^,v^y,,..,^, gy^^ ^^Is is ccrtaiiily not the case, for 
the true simple GraptoLites are perfect 
from end to end. I shaU shortly, I 
hope, describe the new branched dichotomous form under the name of Bichograp- 
s?cs; meanwhile I think I am doing some service by calling the aitention of those 
living near the Skiddaw slates to the unexpected riches of that formation. 
Trails of worms (and those abnormal things called fucoids), are abundant 
enough everywhere in them. But no good list has yet been published ; and the 
formation is almost a virgin one for explorers. 
Can no one find the Lingula flags on the flanks of the Saddleback ? We are 
beginning to disbelieve in mtamorphic rocks being unfossiHferous. — Yours truly, 
J. W. Salter. 
Geological Guide to the Onny Valley. — In commencing a geological 
trip up the Onny Valley, the most convenient place to start from is the 
Craven Arms, a station on the Shrewsbury and Hereford Railway; and 
taking the tui-npike-road towards Shrewsbury for about a mile, a stile is 
reached on the left hand side, whence a foot-path leads across a field near 
the bridge over the Onny River. Proceed along this path about three 
hundred yards and cross over the railroad, then turn down to the river 
and follow up the stream to the top of the meadow— the Wenlock shale may 
there be observed exposed in the river bed, and if the water is low some 
fine specimens of Fhacops longicmidatus may be procured, together with 
Calymene tuberculosa, Canliola interrupta, Loxonema elegans, OrtJioceras sicbun- 
dulatum, BeyricUa tuberculata, and Graptolithus priodon. The most prolific 
beds are just below the fence, close to the left hand bank. Keep on up the 
side of the brook until arriving at a foot-bridge, which cross and immediately 
go into the field above ; nearly at the further end is the celebrated " Onny 
Section," showing the lower members of the Wenlock shale, (or Purple Beds,) 
the Llandovery or Pentamerus limestone, and che upper beds of the Caradoc 
sandstones, lying nearly conformable, and in one continuous section. 
Prom the VYcnlock shale has been procured CJieiruncs bimucmiatus, Encrimrus 
puudatus, B. variolaris, a new trilobite ; Orthis biloba, Beyrichia tuberculata,
