    for itself under the newer lacustrine strata, lifted up the superincumbent mass in ranges of flat-topped hills. Since then, to the east, water has swept over the plutonic and sandstone rocks, and laid down quantities of transported materials impregnated with iron, and some time after there was deposited in the west a conglomerate, imbedding bones of huge mammals, and above it a stratum of brown clay, which immediately preceded the superficial deposits of the black and red soils. P.S.—I have to acknowledge my great obligations to Lieutenant Colonel Alcock, of the Madras Artillery, and Dr. Leith and Mr. Carter, of Bombay, for assisting me in obtaining access to books (or extracts from them), cf which I should otherwise have been deprived. The map of the district described is coloured geologically from an excellent political map given in Rushton’s Bengal and Agra Gazetteer for 1842. The formations between Chindwada and the Mahadewa Hills are laid down from a sketch obligingly furnished to me by Mr. Sankey. jDescription of the Cranium of a Lahyrinthodont Reptile, Brachyops Laticeps, from Mdngali, Central India. By Professor Owen, F.R.S., F.G.S. [With a Plate.]* [Read JuDe 21, 1854.] The fossil obtained by the Rev. Messrs. Hislop and Hunter from the sandstone series of Mangali, about sixty miles to the south of Nagpur, and transmitted for my examination, is a considerable portion of a skull, wanting chiefly the tympanic pedicles and the lower jaw; it is imbed- ded in a block of bright brick-red compact stone, with its upper surface exposed. The skull (PI. XII.) is broad, depressed, of an almost equilateral triangular form ; the occipital border or plain rather exceeding in ex- tent each lateral border, which borders converge with a slight convex curve to the rounded obtuse muzzle. The breadth of the occiput is 4 inches 9 lines, and the extent of each lateral border of the skull in a right line is 4 inches 6 lines. Most of the cranial bones are impressed by rather coarse grooves, radiating in each from a prominence which indi- cates the primitive centre of ossification ; the intervening ridges being in some parts broken up by communicating grooves into tubercles. The orbits (o, o) are entire, of a moderate size, of a full oval form, and situated in the anterior half of the skull. The middle line of the upper surface ot the skull is slightly depressed ; at the upper and fore part of the skull on * Reprinted from the Quarterly Journal of the Geological Society of London, vol. part i. p. 37.—February, 1855.—Ed.
