rich white blossoms, and an arborescent species of Cassia 
with very long narrow seed-vessels, was observed between 
lat. 27° 30' and 19°. . Careya arborea, Roxb, was first met 
with at the Suttor, the clustered fig-tree first at the Burdekin ; 
Grevillea mimosoides. R. Br. and Hakea lorea R. Br. appeared 
first in lat. 26° 42’, Grevillea lanceolata, a new species showed 
iself first at the Suttor, where it was growing on a light 
sandy soil with Pandanus spiralis R. Br.; Grevillea cerato- 
phylla, R. Br. and Acacia equisetifolia were first met with in 
lat. 19°19 The poplar-gum, a species of Eucalyptus with a 
bright green foliage, formed patches of forest along the 
Isaacks, and grew on the stiff hollows along the Burdekin. 
An arborescent Zamia was growing on the heads of Zamia 
Creek, and on Expedition Range in lat. 24° 43/; a 
Cycas about four to five feet high, with pinnate leaves of a 
glaucous colour, on the Burdekin in lat. 18° 45’, and a Scia- 
dophyllum in the valley of lagoons, in almost the same lati- 
tude. A Nymphea was first observed on Brown’s lagoons 
m lat. 24° 45’, and a species of Nelumbium near the Macken- 
Ze river in lat. 230 21°. ; :

. Gulf of Carpentaria, between 18?—16? S. latitude. The fall 
towards the level country which forms a broad belt round — — 
the Gulf of Carpentaria, is much more rapid than the ascent 
from the east coast; and the course of the Upper Lynd is — — 
Much more mountainous and wild than that of the Upper | 
= Burdekin. It is extremely interesting to the geologist to —— 
po observe the same succession of rocks, granite, talchiste, por- — — 
_ Phyry, and sandstone, in descending to the Gulf, which were — 
.. found at the east coast in ascending to the table land. But 
. . limestone was not met with on the west side of the York 
" Peninsula, though it appeared extensively developed on the 
‘Burdekin. Basalt has broken through the various rocks, | 
the level country itself is formed of a clayey ironstone 
Brains of quartz, which extended all round the Gulf 
Essington, and may be considered of a newer for: 
The Lynd was joined by several running creeks, an
