128 THE PROCEEDINGS OF THE LINNEAN SOCIETY upheaval in New Guinea, especially as there has never been any similar evidence found on the east side of the Australian conti-nent. It remains to be seen whether, in this case as in the Southern Australian tertiaries, we have the sign of volcanic activity accompanying the upheaval. Mr. Macleay showed me specimens of true amygdaloidal and vesicular dolerites, taken from the coast of Darnley Island, opposite Yule Island, a distance however of 150 miles. They were in all respects similar to the Victorian pliocene dolerites. The bathymetrical evidence of these fossils show that at least there has been upheaval to the extent of 400 or 500 feet.
