The proximal end is not clearly preserved, but there is some 
indication of a scar of attachment. 
The secondary veins on the narrow wings at the base are well 
preserved, and appear to be wider apart than on the broader or 
upper portions. The furcation is also very distinct, and takes 
place at a slightly more distant point than on the latter. A 
subdivision of the secondary veins on the broader portions of the 
frond is not common, but one is shown at about the centre in 
fig. 3; this is, therefore, a second subdivison. A peculiar ter- 
tiary subdivision occasionally although rarely, takes place near 
the margin (fig. 3), and when so several veins in this condition 
are clustered together. The primary furcation is also peculiar in 
that it occurs in immediate contiguity to the mid-rib, almost 
assuming the appearance of two parallel veins issuing from the 
same initial point. That this is not the case, however, is shown 
by the secondary veins in the narrow basal portion of the frond. 
Oleandridium vittatum, Feistm., differs from the South Aus- 
tralian fossil by its irregular furcation, and the secondary veins 
are often more than once furcate. 
A gentle fluctuation of the margin is shown in Nathorst’s 
figure* of O. tenwinerve, Brauns ; indeed, this irregularity of the 
frond edges is quoted by Schimper as one of the specific charac- 
ters. The secondary nerves are said to be furcate at the base 
only. On the whole O. tenwinerve is the nearest approach to our 
form that I have been able to find, although probably distinct. 
As regards size, an Australian described species, 7. Carruthersz, 
Ten. Woods, may be compared to 7’. (Oleandridium ?) fluctuans, 
the name I purpose applying to the present frond, judging by the 
large fragments of it that have been published by Feistmantel 
from South Africa. + 
Teeniopteris, sp. ind. PI. iv., fig. 1. 
Sp. Char.—Frond linear spathulate, four to five inches long and 
five-eighths of an inch wide, probably petiolate; margins entire, 
not fluctuating; surface plain, not crumpled. Mid-rib very 
strong, one-sixteenth of an inch wide; secondary veins briefly 
issuing from the mid-rib at an acute angle, then diverging at a 
much more obtuse one, and proceeding to the margins more or 
less horizontally, one in the space of half a millimetre, and appar- 
ently all simple. 
Obs.—This frond is so like many Teniopterids that it is 
rendered difficult of determination. Thesubstance of the frond, 
except here and there, has been converted into coaly matter, so 
that the entire venation has not been preserved for inspection,
