Nephelites Berwickense, sp. nov. 
Plate YI., Fig. 9. 
Portions of a leaf ovate or ovate lanceolate, entire. Midrib straight and 
well marked, lateral or secondary veins conspicuous, curved; those on the 
right hand side proceed at a wider angle with the midrib than those on the 
left. In this it resembles the pinna of the leaves of Nephelium , Cupania 
and other genera. 
The lopsidedness of the leaf preserved in specimen No. 84 appears to 
indicate that it is a pinna of some large leaf, and I have included it under 
my genus Nephelites.

Tristanites, gen. nov. 
This name is adopted on account of the resemblance of certain leaves to 
those of the different species of the existing genus Tristania , R. Br. 
Tne characters are those of Tristania. The leaves are ovate to linear 
lanceolate, entire; midrib well marked and straight; lateral or secondary 
veins conspicuous, starting at an acute angle from the midrib, and curving 
round before reaching the margin, where they generally seem to lose them¬ 
selves in the substance of the leaf, but in reality pass upwards and join the 
next lateral vein. These outer portions of the lateral veins which produce 
the appearance of an intramarginal vein in Myrtacece are not generally con¬ 
spicuous in this genus. 
Tristanites angustifolia, sp. nov. 
Plate III., Fig. 1; Plate VI., Fig 7. 
Leaf about 2^ inches in length and § inch in width, lanceolate obtuse, 
base slightly oblique, entire. Midrib strongly marked ; lateral veins starting 
from the midrib at an angle of about 60°, curved and nearly reaching the 
margin ; smaller veins not visible. 
The leaf described is preserved in specimen No. 77, and it might at first 
sight be taken for Eucalyptus , but this similarity disappears on close exami¬ 
nation, There is an absence of the finer lateral and reticulated veins to be 
seen in those species which at all resemble the leaf in question. The leaf 
resembles the leaves of Tristania nereifolia , R. Br., and T. laurina , R. Br. 
That contained in specimen No. 115, and shown in Plate YI., Fig. 7, appears 
to belong to the same species. 
Tristanites Muelleri, sp. nov. 
Plate III., Fig. 2. 
Leaf about 4 inches in length, rather more than j inch wide, lanceolate, 
entire. Unfortunately, the apex is lost and the base not quite intact. Mid¬ 
rib strongly marked and straight. The lateral or secondary veins very 
distinct, distant from one another, curved, losing themselves on approaching 
the margin. Finer reticulated veins not visible. 
The leaf described is contained in specimen No. 79. Although somewhat 
narrower, it follows in the main the type of Tristania conferta , R. Br., and 
T. suaveoleus , Smith. There is an indication at one part of an intramarginal 
vein, which lends all the greater probability to the view that this leaf belongs 
to the Myrtacece. Specimen No. 231 contains a similar leaf.
