The llcv. W. B. Clarke, in his paper on the “ Sedimentary Formations 
of Now South Wales” (1875, p. 102), says that he lias found this Cyclostigma 
together with Lepidodendron notlium, TJng. (Carr.), and thus probably in 
Devonian rocks. I had also a fragment of this form from the Goonoo 
Goouoo beds, and others from another horizon.

Obs. — Amongst the specimens from Goonoo Goonoo, in New South 
Wales, from where Lepidodendron nolhum was already described, there was 
also a small fragment of a stem, which undoubtedly belongs to the genus 
Cyclostigma ; it is in the same rock as the above Lepidodendron. The 
surface shows small, oblongly-rounded impressions, which arc pretty closely 
set, spirally arranged, and have in their upper part a similarly rounded 
tubercle. These impressions are of about the same size as those of Cyclo- 
stigma JdltorJcense , light., but they arc much more closely set; at the same 
time they are larger than in Cyclostigma minutum , light. 
From the fragmentary condition of this specimen I did not assign to 
it a specific name, because, if more fragments were known, it might happen 
that it yet would have to be placed with Cyclostigma kiltorlcense, light. 
On the other hand, it also shows some relation with the next species, except 
that the scars arc more closely set. It is, however, not without interest, as, 
occurring together with Lepidodendron nothum, ling., in beds which are 
lower than the strata at Smith’s Creek, it would help to corroborate the view 
that L. nothum is really different from L. australe, M £ Coy.
