By the side of a cast of the large-fronted ox of Scandinavia, in the case of fossil Bovidæ in the British Museum, is a specimen found in Bawdsey Bog, near Felixstow, in Suffolk, referred to that same species—the only example recorded in England, if exhibition in the cases of our national institution be a record, for it has been nowhere figured or described.

That the determination of the species is correct there can be little doubt, as the specimen was seen and examined by Professor Nilsson on his late visit to this country, and the correctness of the determination was verified by him. It is to this, one of the most interesting but least known species, that we now wish to draw attention. It is interesting because it was probably a species of higher antiquity that lived on to be coæval with the early human races whose relics are found in the deposits of that remarkable border-land between the last geological ages of the Prehuman era and the obliterated first chapters of Human History.

So little is known of Scottish Jurassic Brachiopoda, that any additional information cannot fail to prove interesting. Professor Nicol wrote me on the 16th of April, 1860, that out of a pretty large collection of the fossils of this period sent up to the Aberdeen meeting of the British Association, he found only two species and specimens of Brachiopoda, and both imperfect. That in Sunderland they are most common in the Dunrobin Reefs (by some thought to be Oxford clay, by others Lias), but that the stone is so friable, that the specimens fall to pieces almost at the slightest touch; and that in the sandstone at Braambury Hill, are casts of a large shell, like Terebratula perovalis, but often crushed and distorted.

In 1850, the late A. Bobertson, of Elgin, sent me two beautifully preserved Rhynchonellæ (R. lacunosa?), from Dunrobin, and which will be found figured and described in my monograph; and about the same period, the late Hugh Miller sent me a specimen of T. numismalis, from the Lias of Shendwick, and another of Rhynchonella Bouchardii, from the Lias of Cromarty. Mr. Geikie recorded likewise a Rhynchonella tetrahedra, from the Middle Lias of the island of Pabba.

There only remains now to notice the post-Tertiary deposits to complete this account of the geology of Maidstone. The surface-soil and the earth filling in and covering over the faults and large fissures consist of clay, gravel, “sharp” drift-sand, and fine sand, all being sedimentary deposits from water under different rates of motion. The exteriors of the highest masses of rock show the effects of a powerful erosion continued for a long period of time; but this action was not the dashing of billows, for some surfaces of the rock, although worn to a great extent, have portions of fragile shells standing out from their surfaces, just as in the cavernous gutters of the rock masses of spiculæ jut out from the walls, the loose sand or soft hassock having been washed away.
