_» Recherche and South Cape Coal Measures.—The shales and 
sandstones occupying the low lying country east of South 
Cape, and south of Southport, have been so graphically 
described nearly 40 years ago by Dr. Milligan that little 
more can be added save as to organic contents. * 
It is evident that these beds, containing several coal seams, 
attain a maximum thickness of about 400 feet in the coast 
line between South and South-East Cape. These beds 
evidently succeed the Ida Bay coal measures, and belong to 
the upper mesozoic group. Thus we have in their shales no 
longer any representations of Vertebraria Australis (M‘Coy), or 
Pecopteris Lunensis (mihi), but instead we have abundant 
remains of upper mesozoic forms, viz.: — 
Alethopteris Australis... sae a NECoy: 
Thinnfeldia obtusifolia ... Tat 
Sphenepteris lobifolia _... ... Morris 
Baiera tenuifolia ... “ae eo) Saale 
Zeugophyllites elongatus ... a) Morris 
Phyllotheca Australis... ... M‘Coy 
and abundant remains of the trunks of silicified conifers. 
Localities where beds are best exemplified:—Pedro-Bancho 
‘Hill, Black Swan Lagoon, Pigsties, Catamaran Creek, Cockle 
Creek, Coast between South and South-East Cape. 
The whole of the members are everywhere disturbed or 
overlaid by intrusive greenstones, as in the Jerusalem and 
other basins. 
PECOPTERIS ODONTOPTEROIDES (Morris). 
Pl. vi., fig. 2, 38, 4. 
As there is still much doubt as regards the character and 
identification of the original forms described under the above 
name by Professor Morris from specimens obtained from the 
mesozoic rocks of Tasmania, and probably from sandstones 
of the Jerusalem Basin near Spring Hill, I have considered 
it advisable to review the whole matter at the present time 
with the view of helping to clear up some of the difficulties 
which, in my opinion, have been caused by confounding the 
original types of Professor Morris with at least two other 
distinct forms. 
Professor Morris describes the original type P. odontop- 
teroides as follows :— 
Pecopteris odontopteroides (Pl. vi., fig. 2, 3, 4). f 
“ Frond pinnatifidly bipinnate or flabellate ; pinnz linear, 
elongate, accuminate; pinnule opposite approximate, adnate, 
ovate obtuse, entire; veins nearly obliterated.
