Locality and Horizon . — In the bituminous matter of the shale of the

Sj). Char . — “ Strobilus or cone imperfect, oblong, narrow, cylindrical 
4| inches long and inch in diameter; the longitudinal, striated cylindrical 
core of specimen, about half an inch in diameter, indicates that the central 
longitudinal cavity, or core, occupied fully one-third of the total diameter ; 
bractese emerging from central axis at a slight descending angle, about 20 
in number, from 4 to G mm. thick at base, and tapering downwards to 
margin, where they arc from 2 to 3 mm. thick, and from which they sud- 
denly bend upwards, and form long, thin, leaf-like, imbricating bracts, 
enclosing sporangia cavities or cells, of similar appearance and size to the 
enclosing bractese.” 
Locality and Horizon. — This unique and interesting specimen was 
discovered by Mr. Johnston in the so-called auriferous sandstones of Cam- 
pania, which belong to the Mesozoic Coni Measures of Jerusalem, Tasmania. 
CYCADEACE2E. 
Ohs. — Remains of Cycadeacese are not very numerous amongst the 
Australian fossil plants, and, if we exclude the genus Noggerathiopsis, there 
are hardly any known from New South Wales. 
The fossil genera of Cycadeacece (leaves) are the following:— 
Cycadites, Brgt. Ranges from Carboniferous to Cretaceous. 
JPodozamitcs, Rr. Braun. Rluetic to Wealden. 
Zamites, Brgt. Lower Trias to Miocene. 
Glossozamites, Schimper. ? Permian (Karharbari beds in India) 
to Cretaceous, where it is chiefly developed. 
Otozamites , Rr. Braun. Rluetic to White Jura (Corallien). 
Ptilophyllim, Morris. Jurassic. 
Ctenophyllum , Schimper. Lias to Upper Jura. 
Hioonites, Bornem. Rluetic to Lower Cretaceous. 
Tterophyllum, Brgt. Upper Carboniferous to Wealden.
