Bed h^ lies 17 the pillow-lava, from which it is separated by beds g, consisting of thin-beddeddark bluish-grey drab-brown tuffs that exhibit well-preserved ripple-marks. In thesetuffs there was found a single example of a large Terebratula that closely resemblesLiolhyrella hoehmi Thomson, which is abundant in the tuffs immediately underlyingthe Kakanui limestone. Limestone-bed h- lies from 100 ft. to 150 ft. below bed /*. The tuffs between h^and h^ show conspicuous evidence of current-bedding. The angle of dip of bed h^is 18°, and of bed h- 34°. The result of this difference in the angle of dip is thatas they rise upward in
