Figs. 5,7; 8 (2). Glossopteris indica (Brongn.) Schimyp. 
5, 7. Fragments from cuneate bases of leaves. 
S. Very narrow form with oblique nerves, possibly representing another 
species. 
Fig. 9. Clossogtoris wmpla Dana. 
Fig. 10. Siyillaria sp. 
Brown, coaly rock composed of layers of matted megaspores, probably of 
Sigilluria. 
10 a. Portion of the same rock enlarged four diametors tu show the indivi- 
dual megaspores, which are represented by the collapsed exospores. The tri- 
radiate vent is seen in some of the sporos. 
Fig. Ll. Sigillaria oustratis n. sp. 
Fragment of cortex on which the leaf scars are seen, though the Jeaf-cushions 
are very obseurely defined. 
lla. Leaf scar enlarged, with part of its indistinct leaf cushion. From the 
left of the specimen. 
11 b. Similar enlargement of a sear with more prominent cicatricules. 
Ile, ll d, Sears in which the marked subcutaneous enlargement of the 
parichnoi is shown. 
PLATE VI 
Figs. 1-4. Glossopleris occidentalis n. sp. 
1. Apex of the leaf. The fine parallel uervation is seen to be nearly at a 
right angle to the border. 
2. Sessile and cordate base, showing vory wide {lat midril, and nervation as 
in Figure 1. 
3. Frayment of middle of leaf, showing very broad midrib, and the nervation 
coarsely meshed near the midrib, fine, parallel and very distantly anastomosing 
after turning outward to pass to the border. 
The obliquity of the nerves, due to contraction alone the abraded midrib. 
is the greatest seen in the specimen. 
4, Fragment with typical nervation. 
4a. Portion of the same enlarged to four diameters to show the nerves elon- 
gately meshed near tho broad midrib, and parallel, very close, and rarely anasto- 
mosing near the border. 
Figs. 5, 6. Glossopteris sp. 
Petiolate, concavo-convex, thick coaly seale leaf.
