similar to that in Retinosporites, Holden, and should anatomical details become 
available, it may be found necessary to transfer this species to the genus 
Retinosporites. 
These plants form a large proportion of the Talbragar collections, and 
comprise some quite large fronds more than 12 cm. long and 8 cm. across.

The specimen figured (F3166) is portion of a branch about 10 cm. long 
with spirally arranged, fleshy, pointed leaves, about l -2 cm. long, and it may 
with little doubt be referred to the genus Pagiophyllum. It does not appear 
to differ in any essential feature from the common Jurassic form, P. peregrinum, 
but a single specimen, not too well preserved, is perhaps hardly sufficient to 
establish specific identity. 
Seward’s definition of the species is as follows : “ Vegetative shoots 
monopodially branched, bearing crowded, spirally disposed, fleshy leaves. 
The leaves vary in shape and position ; they are usually broadly triangular, 
sometime reaching a length of 5 mm., imbricate and fairly closely appressed 
to the stem ; in some shoots they are more open in arrangement, and more 
distinctly falcate. The back of the leaves bears a broad median keel, and the 
lamina is frequently characterised by numerous longitudinal striations or 
wrinklings; the apex of the leaf may be obtuse or acuminate.” 
Pagiophyllum does not appear to have been previously recorded from 
Jurassic rocks in Eastern Australia; it is known from the Maryborough Series 
(Marine), and from the Burrum Series of coal measures in Queensland. The
