The Austrian fossil has also its pith preserved containing 

 stone-cells, which strengthen the attribution to Podocarpus. 

 There is little doubt that these fossils are early members of 

 the Podocarpaceie. 



V. 5456. Type-specimen. A small block of silieified wood, now 

 measuring C'5 x 2*8 x 2 cm., and a piece cut from it. 

 The specimen consists of a straight splint of secondary 

 Avood only, without any matrix, and it shows the 

 wood-texture very clearly in all directions. The 

 petrifying medium is very close and hard, partly 

 white and partly very dark brown, cutting to a rich 

 golden colour in the sections. 



V. 5456 a. Transverse section of the above. This shows several 

 well-marked annual rings with the largish tracheids 

 and resin-containing xylem-parenchyma, but the 

 transverse section in the type is not nearly so well 

 preserved as in the co-type, which is the one figured. 



V. 5456 b. Figured, text-fig. 62. Tangential longitudinal sec- 

 tion of the above, partly very well preserved. It 

 shows the height of the medullary rays, the numerous 

 resin-containing xylem-parenchyma and their cross- 

 walls, and the pitting of the tangential walls of the 

 tracheids in some places. 



V. 5456 C. Figured, text-fig. 61. Longitudinal radial section, 

 locally very well preserved and showing the pitting 

 on the tracheids, the resin-containing xylem-paren- 

 chyma, and the resin-containing ray-cells. In some 

 places the large pits on the radial walls of the ray- 

 cells can be well seen.

V. 5151. Co-type. A wedge-shaped and weathered splint of 

 secondary wood, now 8'5x3'5xl'5 cm. The end 

 is rounded and evidently waterworn before it was 

 petrified. There is also a small second piece from 

 which the sections have been cut. The whole is free
