V. 13208 b. Two further sections, similar to the above, in which 

 the annual rings are seen a little more clearly, as the 

 sections are slightly thicker and the contrast more 

 marked. 



V. 13208 C. Figured, PL XVII, figs. 1 & 2 ; text-fig. 54. Median 

 radial longitudinal section through the pith, in which 

 the pith-cells are largely marked by black mineral 

 granules. The protoxylems show very well in several 

 places. The exit of a leaf-truce through the wood, 

 which runs horizontally through a medullary ray, can 

 also be seen. The medullary my-cells are clearly seen 

 in outline, but only show their pits in a small area 

 towards the middle of the section. The bordered pits 

 on the tracheids are to be seen in many places. 



V. 13208 d. Oblique tangential section, showing the exit of a 

 small branch. In this, though they are not satis- 

 factorily preserved, the low medullary rays can be well 

 seen. 



V. 13208 e. Another rather similar section to the above, 

 showing the rays partly radially and partly t;m- 

 gentially. Several small leaf-traces cut in tangential 

 section can be seen. 



Kentish Hag ; Iguanodon Quarry, near Maidstone. 



Presented by tlie Committee of the Maidstone Museum, 1912. 



Included in the above species should probably be a second 

 small twig from the same locality, in which, however, the 

 structure is less well preserved and there are no remains of the 

 cortex. The twig is about 1 cm. in diameter. From the small 

 piece given by the Maidstone Museum sections were cut, which 

 show that the phli is the best-preserved feature of the twig. 

 In the pith are large, very much thickened stone-cells (text- 

 fig. 55, c.). This makes it difficult to compare with the type, 

 because the pith is there the least well-preserved part, and I am 

 doubtful whether stone-cells are present in it. The other 

 features of the present specimen, however, all agree with those 

 of Cuprcssinoxulon cryptomcrioid.es, so far as they are observable.
