74 PROCEEDINGS OF THE GEOLOGICAL SOCIETY. [Dee. 8, 
Budleigh species, occurs abundantly in the reddish sandstone, or 
quartzite, of May, near Caen, in Normandy, a rock referred by most 
geologists to the Caradoc, and asserted by Mr. Salter to lie above the 
Armorican Sandstone with Lingula Lesuewri—a formation seemingly 
part of the great slaty series of Angers, therefore far underlying the 
May sandstone ; he further adds, “In brief, then, the mass of the 
Budleigh-Salterton fossils are Norman types of the May Sandstone, 
and some belong to the ‘Grés Armoricain;’ several of the species have 
been already named in France, and some of the more conspicuous 
shells, though apparently undescribed, are characteristic of the rocks 
on both sides of the Channel.” I must nevertheless observe that 
very few of the forty species of Brachiopoda found at Budleigh- 
Salterton have hitherto been obtained from the Middle and Lower 
Silurian rocks of Normandy and Britain*. Mr. Vicary has never 
yet found Orthis redux ?, var. budleighensis, associated with Lingula 
Lesueurt; indeed very rarely do we find this last-named shell in 
company with other Brachiopoda in the same pebble. It is, 
moreover, not easy to be certain about .the correct identification of 
* some of the incomplete internal casts and impressions of the Bud- 
leigh species of Orthis and Strophomena, which may be, most pro- 
bably, Devonian forms; so much do the species of those genera in 
the two periods sometimes resemble each other, notwithstanding 
their specific distinctness. 
Now, as it is quite certain that all the species found in the same 
pebble with one or more of those forms believed to be correctly 
determined must be of the same age, we shall find, as far as our 
present imperfect knowledge will carry us, that only three or four 
of the species of Brachiopoda have been, with some degree of cer- 
tainty, referred to the Lower-Silurian period; while eight or nine, 
supposed to be Silurian, and which have occurred in the same stones 
with Orthis redux, Barr.?, var. budleighensis, must remain for the 
present of undetermined age, although they possess much more of 
the Devonian than of the Silurian facies. Twelve or thirteen are 
unquestionably Devonian shells, while the remaining fourteen, either 
being new or not having hitherto occurred or been found with any 
of those already recorded as Silurian or Devonian, cannot yet with 
certainty be correctly located; but they seem, to my eye, to pos- 
sess In most cases a very decided Devonian aspect. 
It is highly probable that when the species of the other classes 
also occurring in these pebbles shall have been carefully and criti- 
cally examined, the true age of the fossils generally will be esta- 
blished, as the whole series must be taken into consideration before 
we can expect to arrive at any definite conclusion. But all tends to 
show that the great bulk of the fossiliferous pebbles at Budleigh- 
* Mr. Godwin-Austen informs me that he believes these boulders to be of 
French origin, and that he knows of a pebble-band belonging to the New Red 
series in Normandy, identical with that at Budleigh—but that if I ask whence 
do the pebbles come, and where is the parent rock, he must answer that he does 
not know, but that in Lower Normandy the paleozoic series is not well exposed 
and has been much denuded.
