Ohs. Both Mr. Eobert Kidston and tlie W riter are quite in accord with Prof. 
McCoy in considering the plant described by Mr. Carruthers under the name of 
Lepidodcndron notlmm, Unger, as identical with L. australe, McCoy.* Mr. Kidston 
remarks in his notes on the Queensland plants : — “ The type of Lepidodendron notlnm, 
Unger, t on account of its imperfect preservation does not appear to afford any specific 
character from external markings, by which other specimens can be satisfactorily identified 
with it ; therefore the identification of the Queensland or Tasmanian specimens with 
Unger’s plant does not appear admissible.” Prof. McCoy remarks that “ The scars are 
so much larger and fewer on approximately the same sized branches (i.e., of L- 
australe), “that it is not desirable to make such a reference” {i.e., to L. nothum, 
Unger). Lepidodendron nothum, Carruthers {non Unger), is believed by Mr. Kidston to 
include two species, belonging in part to L. australe, McCoy, and in part to LeptopMeeum 
rhomlieum, Da\vson.+ According to this view, Mr. Carruthers’ figures (PI. 26, loc. cit-, 
figs, ll-ldi), must be referred to L. australe, and the remainder given on his plate 
(figs. 1-4, G-9) to LeptophloBum rhomlieum. The differences in the form of the leaf-scar, 
the position of the vascular eicatricnle, and mode of growth of these specimens,, seems to 
prohibit their being included in one species.’ ’ The latter figures have a great resemblance 
to Lepiophlasum rhomlieum in the form of the scar and position of the cicatricule.

Ohs. This Lycopod was recorded as a Queensland species hy the late 
J. E. Tonison Woods. It occurs as compressed branches, with impressions of distal 
narrow-pointed leaf-like scales. -
