angle (with regard to tlie position of the figure) the auriculation is somewhat 
indicated, and also the distribution of the veins agrees with that of an 
Otozamites. The leaflets arc closely set, touching at the base, alternate, 
oblongly ovate, with the apex rounded ; the veins are numerous, radiating 
hito the leaf, and forked. 
Amongst the species of Otozamites already described the closest ally 
to the Australian form is Kurr’s Otozamites Mandeslohi, the diagnosis of 
which is given above. I could find no difference between the two, except, 
perhaps, that in our specimen the leaflets are somewhat more symmetrical. 
Otozamites llandeslolii , Kurr, sp., was, it is true, described from the 
Lias of Ohmden in Wurtcmberg, but this could of course form no objection 
to a comparison of both specimens. 
Locality and Horizon . — In the Upper Mesozoic coal beds at Talgai

Ohs. — The above is the general diagnosis of the leaf. According to 
my investigations the chief character lies in the leaflets, which have the 
superior (or anterior) basal angle rounded, sub-auriculate and free, while the 
lower (or posterior) angle is fixed and decurrent behind the rounded and free 
angle of the next lower leaflet.
