Salter— Budleigh Salterton Pebble-Bed. 9 
not yet fully come to light, must be reserved for a future 
communication. There is a small Silurian district near Meva- 
gissey and Veryan, in Cornwall, first made known by the 
collections of Mr. Peach, and afterwards traced in detail by 
Professor Sedgwick, and this seems to be the counterpart of 
the Normandy rocks, and to contain several of their character- 
istic fossils.* We are not yet in a position to affirm that these 
beds, at Gorran Haven and the headland of the Dodman, are 
identical with those which supplied the Budleigh Salterton 
pebbles; but at least they belonged to the same French group, 
and are wholly unlike the Silurian beds of Wales and the 
Border Counties. Yet the distance of these Cornish and Devon 
localities from the nearest point in Wales where Lower Silurian 
rocks are known, is not more than 90 miles; while they are 
150 or 160 miles (in a north-west line) from the fossil-bearing 
localities in Normandy. 
Fossils from the Old Pebbles at Budleigh Salterton.—The 
fossils found in the pebbles of the pebble-bed under notice will 
not be fully enumerated here. They consist chiefly of Tri- 
lobites, large Bivalve Shells, allied to Modiola, Arca, and 
Nucula, and Brachiopods, of the ordinary genera known to us 
in Silurian rocks. The Trilobites are well-known French 
species; so are some of the most conspicuous Bivalves, and 
the great Lingule and Spirifere, though not at all like any- 
thing in Wales or Westmoreland: some of them have been 
already described by the French geologists, and particularly 
by M. Marie Rouault, of Rennes. It will be of interest to our 
brother geologists of France to see the fossils long familiar to 
them through their own research (though few of them have 
yet been figured), illustrated from specimens gathered from 
the shore of Devonshire. Leaving the bulk of the fossils 
obtained from these interesting pebbles to be described in the 
Geological Society’s Journal, I subjoim a description and 
figures of one or two Sea-weeds (?) from the collection of Mr. 
W. Vicary, and of a new Crustacean, from that of Mr. R. H. 
Valpy, of Ilfracombe.f The latter is of peculiar interest, 
and well worthy of further search being made for the missing 
portions of the body. 
* A different conclusion might be drawn from the lists given by Prof. Sedgwick 
and M‘Coy (Quart. Journ. Geol. Soc., vol. vill. p. 18); but all the specimens that I 
have seen are of species distinct from the British; and some, at least, unnoticed 
by M‘Coy, are true French species—Calymene Tristani, for example. 
{+ This specimen is now in the British Museum, having been presented to the 
Geological Department by the discoverer.
