It Will interest some of your readers to hear that remains of Bos primigenius have recently been obtained from the true till or lower Boulder-clay of Scotland. The specimens hitherto found appear to have come either from the fine Glacial brick-clays, which are posterior in date to the larger portion of our Boulder-clay, or from deposits of still later age. A few days ago I heard that the navvies employed in making the new “Crofthead and Kilmarnock Extension Railway” had come upon what was described to me as a “wounderful big bull's head.” I lost no time in visiting the locality, and saw the fossil in the possession of Mr. John Strain, C.E., who allowed me to examine it, and was afterwards kind enough to accompany me to the railway cutting in order to point out the exact spot from which the relic was taken. The skull is in rather an imperfect state, and only one of the horn-cores remains, the other having been broken off near the base. The perfect core measures 31 inches in length along the outer curve, and gives at its base a circumferences of 14 inches. The breadth of the forehead between the horns is 10 inches. From the character of the flat forehead, from the origin of the cores, and from the direction and curvature of the remaining one, there can be no doubt that the skull is that of Bos primigenius.

If any apology be needed for the introduction of these notes in the pages of the Geological Magazine, the excuse we would give is that geologists are, at the present time, being reproached, and perhaps deservedly, for attempting to generalize in cases which, to a great extent, depend upon chemical and physical actions, without having given these sciences that amount of study and consideration which their vast importance merits.

I have in previous papers given some account of the remarkable Lower Greensand deposit at Upware, and have also described three new species of Terebratulidæ from this locality. Having obtained additional specimens of the rarer forms, and several new species, and having received many valuable suggestions from Mr. Davidson and Mr. Meyer, I propose in the present paper, first to describe some of the new species, then to make a few remarks on the numerous species of Brachiopoda which occur in this deposit, and finally to indicate their distribution in the Lower Greensand deposits of this country.

Roslyn or Roswell Hill Clay-pit has long been a standing puzzle to Cambridge geologists. I have visited it several times, and have notes upon it made in 1853 and in 1856. I was there in November, 1866, having, by Professor Sedgwick's permission, the the assitance of Mr. H. Keeping.

The gravel beds of Finchley, which belong to the Drift or Boulder-clay series, have yielded to the researches of Mr. N. T. Wetherell, of Highgrate, many specimens of Flints, containing fossils of the Chalk formation,—of these, the genera Inoceramus and Pecten are most abundant, associated with which are casts of Ammonites, and specimens of Terebratula, Rhynchonella, Dianchora, Lima Hoperi, Spondylus spinosus, and many Echinoderms, as Micraster, Cardiaster, (similar to one from Northfleet,) two or three species of Cidaris, Cyphosoma, Ananchytes, Galerites, but with these it is important to notice there are sometimes found silicified specimens of Venericardia planicosta, a condition in which these shells are rarely found in their original Eocene beds.

Professor king instituted the genus Schizodus for the reception of certain species of bivalves occurring in the Permian and Carboniferous systems, which had previously been quoted under the generic title of Axinus. In Dr. Woodward's Manual of Mollusca, 2nd edit. p. 431, Axinus is retained for these shells; and Schizodus is reduced to a synonym, because the name applied by Professor King had previously been employed by Mr. Waterhouse.
