a superficial Post-Tertiary deposit, 18 feet thick, covering some thou- 

 sands of acres. The contiguous Lai Lai lignite-basin is a mile long by 

 three quarters of a mile broad ; and the chief bed of lignite is 128 feet 

 thick at one spot, and is followed by alternating beds of lignite and 

 clay. R. E., Jun.

Considers that the hollows separated by ridges in which auriferous 

 drift deposits have been accumulated in the gold-fields of the Lachlan 

 and Currajong, N. S. Wales, resemble on a much smaller scale basins 

 of the ocean-bottom of different depths, separated by ridges of various 

 widths and extent, which have been brought to light in the Indian 

 Ocean, through the ' Challenger' expedition. . R. E., Jun.

Recent soundings have brought to light a submarine valley north- 

 easterly from Moreton Bay. It is greater than that between the S. 

 coast-line of Australia and New Zealand. Considers the phenomena 

 exhibited by the opposite coasts of these countries to indicate that great 

 rents and denudation in the earliest periods of our geological history 

 were the result of depression and submergence. R. E., Jun.

 some observations as to the formation of the Canterbury Plains. 

 Trans. N. Zealand Inst. vol. viii. pp. 369-375. 

 Lakes must have been remarkably numerous in New Zealand during 

 Pleistocene and Recent times. The gravels of the Canterbury Plains 

 have been deposited in their present form through the agency of lake- 

 waters. R. E., Jun.

 Names places in which trap-dykes and other igneous rocks may be 

 met with. Criticises Mr. Purnell's paper " On the Wanganui Ter- 

 tiaries" (see Geological Recoed for 1875, p. 159), and does not agree 

 with him as to the presence of a submarine volcano in the Wanganui 

 district. R. E., Jun.
