406 Prof. T. G. Bonney—Pebbles in the Bunter Beds. 
and schisty or slaty rock. In the pebbles from the Bunter I find 
quartz with the same inclosures, even to the occasional presence of 
small acicular prisms of a pale greenish mineral (which I cannot 
venture to name), felspar, which, though much decomposed, still 
shows resemblance to the above, and occasional bits of rather similar 
altered rocks. I think, therefore, I am justified in identifying these 
pebbles with the Torridon sandstone, seeing that it is a rock which 
even macroscopically is of a marked and exceptional character. This 
additional evidence proves that those authors who considered the 
Bunter pebbles to have been largely derived from the rocks in the 
North-west of Scotland were right. 
There is, however (as I have for some time suspected), a second 
quartzite represented in the Bunter pebble-bed. This is very 
variable in appearance, being sometimes coarse, sometimes fine. It 
is more granular and altogether less compact in texture, being often 
rather a hard grit than a true quartzite, and frequently contains 
many specks of decomposed felspar, resembling® more the quartzites 
of Budleigh Salterton, the Lickey and Hartshill. To this rock 
belong, so far as I have seen them, the pebbles collected by Mr. 
Percival and Mr. Jennings.! Specimens of this are not unfrequent on 
Cannock Chase, and appear to me to become more common in the 
district about Birmingham and Bromsgrove. I have already found 
two or three specimens of this rock from the neighbourhood of 
Rugeley containing numerous fossils, while the only trace of organisms 
which I have been able to discover in the other rocks have been two 
instances of obscure annelid tubes. One containsan Orthis, which struck 
meas resembling O. redux; so, as usual in a paleeontological difficulty, 
I trespassed upon the kindness of Mr. Etheridge, who thus writes : 
“The Orthis is O. redux, var. Budleighensis, Dav. This shell occurs 
both at Budleigh Salterton and Gorran Haven in Cornwall, some- 
what abundant at both places. I should not be able to distinguish 
the Cornish specimens from those of Budleigh or your specimen in 
the pebble from Rugeley. Lithologically and zoologically they are 
identical. So also with the Lickey specimens, from which place, 
indeed, your pebble might have been derived. In the redder and 
coarser sandstone or quartzite there is a Rhynchonella sp.? and pro- 
bably O. calligramma, and easts of the ossicule of a Glyptocrinus. 
These are all the organisms I can make out.” 
I have always doubted whether the Lickey rock was likely to have 
contributed to the Bunter pebbles, chiefly because I could not 
identify exactly any of them with the Lickey rock as known to me; 
but the other day Mr. Etheridge showed me a specimen from Long- 
wood, * on the S.W. side of the range (where I had never been); 
which contained several fossils, as above, and was exactly like this 
Bunter rock. As it is, from physical considerations, almost impossible 
that Cornish pebbles can have made their way hither, and as these 
less altered fossiliferous quartzites certainly seem more abundant on 
the Worcestershire side of the county, I agree with Mr. Etheridge
