at an acute angle, linear or cuncate, bifurcating with one simple free vein to 
each lobe.” 
Locality and Horizon. — At Mosewood Scrub, Ipswich, not common 
(Carbonaceous beds, Mesozoic, ? Jurassic). 
Trichomanides Ettingsiiauseni, Johnston. 
Trichomanides Ettingsiiauseni, Johnston, loc. cit., 1885, p. 26. 
Sp. Char. — “ Erond pinnate (or bipinnate ?) ; pinme delicate, mem- 
branous, narrow, with closely adpressed, simple, distant, alternate pinnules, 
similar in character to winged rachis ; pinnules simple, linear, sub-decurrent 
towards winged base, slightly diverging towards bluntly pointed apices. A 
simple nerve traverses branches and simple pinnule, as in the existing 
Hymenopliyllv/m rarum , Br. Length of pinna, 3 inches ; length of pinnules 
from junction of median nerve to apex, 15 mm. ; breadth of pinnules, 1} 
mm.” 
Locality and Horizon . — In the Spring Hill beds, Tasmania (Upper 
Mesozoic, Jurassic?). 
Trichomanides spinieolium, Ten. Woods. 
Trichomanides spinifolium, Tenison Woods, loc. cit., 1883, p. 65, Tab. 3, f. 7. 
Sp. Char. — “ Erond evidently somewhat stiff, spreading, dichotomously 
dividing, bipinnate ; pinme opposite, or nearly so, long, linear, and, together 
with the rachis, membranaceously winged ; pinnules nearly opposite or 
alternate, very short, and quite acute, the apical one long and linear ; veins 
thick, simple, free.” 
Locality and Horizon . — At Hose wood, near Ipswich, Queensland 
(Carbonaceous beds, Mesozoic, ? Jurassic). 
Genus — AIlCIIiEOPTEBIS, Dawson. 
This genus was named by Schimper Dalccopteris. Dawson erected the 
above name. D. Stu-r, in his “ Culmflora des Mahriscli-Schlesisclien Dacli- 
schiefers,” lias added new observations and given a list of the various species 
of Archceopteris known up to that time ; amongst them is also an Archceoptcris 
dissecta, previously known as Cyclopteris dissecta, from various places in the 
Lower Carboniferous strata of Europe. Amongst the Australian fossils there 
are also several species which, I think, may be rightly placed with this genus.
