that they were not obtained from the parent rock. It is most probable that they were found either in a boulder- or drift-deposit, or, like those of Mr. Shenton, in the bed of some dry creek or river. This opinion is strengthened by the fact that the surfaces of many of them must have been exposed, as they are still covered with recent lichens.

Queensland Mesozoic Fossils.
The next series of organic remains to which I shall refer are, from the variety they present, of considerable interest. They have all been forwarded to me by the Rev. W. B. Clarke, F.G.S., of St. Leonard's, New South Wales. They would have been described some time since but for the difficulty attending the determination of their precise geological age, and my desire to be furnished with additional specimens, and especially with samples of any clays or marls with which they might have been associated, for minute examination. Long droughts, however, and other unforeseen circumstances have prevented their reaching England before.
Although a few specimens have been added by the Rev. W. B. Clarke, the series I have to notice is the same that was placed in the hands of Professor M'Coy for determination by his Excellency Sir Henry Barkly, when Governor of Victoria. [They were included in a list (nos. 1-50) published in ' Recent Geological Discoveries in Australia,' by the Rev. W. B. Clarke, p. 50.]
