A. Howitti, M‘Coj, Prodr. Pal. Victoria, loc. cit., 1S7G, p. 2i, PL XXXVI, figs. 1, 2, 2a. 
„ Teuison Woods, loc. cit., 1883, p. OG. 
Sp. Char. — “ Pinnae upwards of 4 inches long and about 1^ inches 
wide ; pinnules sub-opposite, imbricate, obliquely ovato-rhomboidal, narrowed 
to the base, which articulates to the petiole so as to appear slightly decurrent 
on one face and obliquely inserted on the other ; terminal pinnules nearly 
the size and shape of the lateral ones, but equilateral ; average length of 
each pinnule, 1 inch 1 line ; width, 6 lines ; nerves slightly radiating, slender 
(about 14 inches 3 linos across the middle), with two or three dichotomous 
branches from base to upper margin; edges only slightly lacerated.” 
Ohs.- — Allied to A. Jaclcsoni (Upper Devonian beds of Gaspe) and to 
the A. hibernica (Upper Devonian of Kilkenny and Berwickshire). 
Locality and Horizon. — Abundant in the olive flags of Iguana Creek, 
Victoria (Upper Devonian).

Arclncoptcris Wilkinsoni , Feistmantel, loc. cit., 1870, p. 148, Pl. VI, figs. 3, 4 ; PL VII, f. 1. 
Sp. Char . — Uoliis pinnatis ; rhachi stricta, striatula, quondam furcata; 
segmentis (pinnulis) subalternis, oblonge, ovatis, pinnatifldis ; laciniis sub- 
altcrnis, cuneiformibus, basi angusta dccurrentihus, incisis ; lobis denticulatis, 
tenninalibus bi-trilobatis, inciso-dcntatis ; nervis crebris, flabellato-dicliotomis. 
“ Proud pinnate ; racliis straight, somewhat striate, sometimes forked ; 
segments of the pinnules subalternate, oblong, ovate, pinnatifid ; segments 
or slits subalternate, cuneiform, narrowed at the base, decurrent, incised ; 
lobes denticulate, the terminal ones bi-trilobed with incised dentations ; veins 
very close, flabellately dichotomous.” 
Obs. — Amongst the known forms of Archceopteris, the nearest allies 
to this Australian species are A. lyra, Stur,* and A. dissecta, Gopp., sp. ; but 
the pinnules are longer, the lobes are wider apart, longer and more slender, 
and themselves again incised. 
Locality and Horizon. — At Smith’s Creek, Stroud (Lower Carboni- 
ferous).
