The specimen is hardly sufficiently complete to decide its nature and 
systematical position Avitli absolute certainty ; but supposing it to be, what it 
most probably is, a fragment of a fern trunk, and, taking the disposition of 
the scars to be quincuncial, I thought it would bo more correct to place this 
specimen with the genus Caulopteris , as there are not sufficient characters 
for placing it anywhere else, or for making it the type of a new genus. I 
have given the following diagnosis : — 
Sp. Char . — Trunco arboreo, mediocri, superficie cicatricibus ramorum 
(foliorum) notato ; cicatricibus in quincunce (spiraliter) dispositis, transverse 
oblonge-ovalibus, paulum prominentibus, lateril>us linea decurrente notatis ; 
superficie interna cicatriculis parvulis vasalibus, 7 ad 8, repleta. 
The species is named in honor of Mr. P. P. Adams, Surveyor- General 
of New South Wales, to whose eminent exertions is due the inauguration of 
the present Geological Survey of New South Wales. 
Locality and Horizon . — In the Newcastle beds, at Newcastle, New 
South Wales (? Permian). 
C.— LYCGPODIACE®. 
Ohs . — The various forms of this class of plants are largely represented 
in the true Coal Measures in Europe and America. In Australia they do 
not, however, occur within the coal seams, but in New South Wales in certain 
beds, even below the Lower Coal Measures, and in similar beds in Queens- 
land, and partly also in Victoria. 
Schimper, in ZitteTs “Handbuch der Paleeontologie” (1880, II 13d. , 2 
Lief.), divided the Lycopodiaceac into two groups : — 
1. Group — Isosporeac ; Pamily, Lycopodiese. 
2. Group — Heterosporese ; Pamilies — Selaginelleae, Lepidodendreae, 
Isoeteae, Sigillarieae. 
All the Lycopodiaceae to be described from Australia belong to the 
family Lepidodendreae. 
Genus— LEPIDODENDllON, Sternberg. 
Lepidodendiion australe, Coy.
