136 RECORDS OF THE AUSTRALIAN MUSBTTM. 



In the third specimen there are certainly eight fronds visible, 

 and possibly portion of a ninth, but this example is otherwise 

 particularly valuable for it shows evidence of the minute struc- 

 ture of the caudex; the venation is also remarkably well preserved. 

 (PI. xxiv., fig. 2.) 



The fourth individual is a similar specimen to fig. 2, in that 

 there are the remains of caudex structure, with five or perhaps 

 six radiating fronds, being, in the present instance, impressions of 

 the upper surface (PI. xxiv., fig. 4). Attention is specially directed 

 to tlie frond on the upper left hand protruding from below the 

 two fronds immediately above it, and the two on the right hand 

 projecting from a still lower level. 



The fifth specimen displays a small caudex surrounded by 

 seven fronds, one of them a young frond, and all again impressions 

 of the upper surface. 



The sixth example consists of two small individuals contiguous 

 to one another on the same piece of matrix, one of which is shown 

 in PI. xxiv., fig. 3. Each possesses three fronds, or portions of 

 three, much shorter and wider than in any of the preceding 

 specimens, and to all intents and purposes pyriform in outline. 



The remaining specimens are preserved in profile. The first 

 (PI. XXV., fig. 5) is a portion of a caudex, with at one end a set 

 of attached fronds, four or perhaps five, forming a kind of corona; 

 and a second series, six or seven in all, at the opposite end, 

 detached and bent backwards out of position, but guided by the 

 evidence of other specimens, there is reason to believe that, 

 although detached, they are practically in siiu. Immediately 

 above the latter, on one side of the caudex, is a round depression, 

 and half way up it on the other is a small protuberance. Amongst 

 the fronds at the end first described is a small somewhat pyriform 

 scale-like body. 



The second specimen seen in profile (PI. xxvi., fig. 6) is a highly 

 important one, in fact one of the most important of the series, 

 consisting of a short portion of caudex, surmounted by a crown 

 comprising six or seven fronds, and a couple of the scale-like bodies, 

 already noticed in connection with PI. xxiv., fig. f). On the face 

 of the crown are what I take to be leaf-scars. On the left of the 

 figure one of the frond petioles is definitely attached to this scar- 

 bearing face, and on the right is a petiole disappearing beneath 

 the matrix, and reappearing beyond in frond form. 



The third fossil (PI. xxiv., fig. 7) is part of a caudex seen partly 

 in a transverse view and partly in profile, in the former case dis- 

 playing portions of three fronds, radiating therefrom. On the 

 right hand side of the caudex is one of the wart-like protuber- 

 ances described in PI. xxv., fig. 5.
