32 
in the lower and middle portion of the frond. Fertile fronds, similar in form to the 
sterile ; the segments of the same shape, but somewhat straighter, and with an 
irregularly serrate margin ; the sori are oblong in shape and parallel to the secondary 
veins.” 
As has already been pointed out (p. 30), C. denticulata differs from C. australis 
only in the pinnules having a denticulate margin. 
Description of the Specimens. —A single example occurs in the Malvern Hills 
collection, in which the margins of the pinnules are clearly denticulate. Similar 
leaflets from Mataura Falls are figured on Plate IV, fig. 6. This is an enlargement 
of three pinnules seen in a specimen in the British Museum collection (V. 11700). 
They are falcate, and the margins denticulate. The lateral veins are, as a rule, 
twice forked. 
Remarks. —This species is incidentally mentioned by Kidston and Gwynne-Vaughan(l) 
as occurring with Osmundites Dunlopi in Jurassic rocks near “ Gore ” (? Waikawa). It 
is more probable, however, that the species in question was Cladophlehis australis. The 
only other record from the Southern Hemisphere, so far as I am aware, is the 
undoubted one from Grahamland, which was made quite recently by Halle(2). 
Occurrence. —Malvern Hills (? Lower Jurassic); Mataura Falls (Lower Jurassic). 
4. Cladophlebis sp. Plate IV, fig. 7. 
Description of the Specimen. —A small fragment of a pinna, in which the nervation 
of the leaflets is clearly marked, is figured twice enlarged on Plate IV, fig. 7. The 
pinnules are short and fairly broad. Unfortunately this specimen is too imperfect 
to permit of specific determination. 
Occurrence. —Waikato Heads, Auckland (Neocomian).
