Mr, Buckland on the Geology of 
rable flocks of small birds. Such rocks are also liable to contain the 
exuvise of modern land shells. 
NEW SOUTH WALES. 
The specimens from New South Wales were collected in the in- 
terior, i. e. on the west side of the Blue Mountains ; and as their 
localities are not specified, it can only be stated of them generally 
that they afford indications principally of primitive rocks and trap. 
The former present several varieties of granite, with some specimens 
of mica-slate, clay-slate, and serpentine. Of the trap rocks there are 
many kinds, and a considerable variety of coarse jaspers of differ- 
ent colours, with some imperfect agates apparently derivative from 
the trap. There is one specimen of dark grey limestone which re- 
sembles the transition lime of the English series. I have seen 
other specimens of this kind of limestone in a similar collection 
made on the same expedition, and transmitted to Mrs. Hare of 
Shrivenham, some of which afford varieties of compact marble, 
others are coarsely crystalline and slaty ; there are also a few varie- 
ties of quartzose sandstone interspersed with specks of decomposed 
felspar. 
There is nothing in any of the specimens indicative of valuable 
metals or precious stones, or any kind of animal or vegetable re- 
mains ; to the collecting of which latter it is of the highest impor- 
tance that the attention of travellers in all distant countries should 
be directed, and more especially in this, where the character of 
many of its present animal inhabitants is so singularly peculiar. 
It may be observed of these rocks, that they bear a general resem- 
blance to those which have been just described from the island of 
Madagascar. Both series announce the presence of primitive and
