52 MR ROBERT KIDSTON ON 



PI. I. fig. 4. 



The bracts have almost entirely been shed from this example, only a few at the base 

 of the cone remaining attached to the axis, which in this naked condition shows well by 

 the scars of the fallen bracts their spiral arrangement. At a on fig. 4 is one of the 

 lanceolate bract-like structures (shown enlarged at fig. 4a), which congregate round the 

 base of the cone. The pedicel is covered with the small apiculi, which are also indicated 

 on fig. 4". 



The slab on which this cone occurs has many isolated bracts scattered over its 

 surface, some of which, as well as a fragment of another cone and pedicel, are shown in 

 the figure. 



PL I. fig. 5. 



Here two cones are seen to spring from the top of the same pedicel. This is 

 probably an abnormal condition. The cone to the right is complete, and shows well its 

 narrow cylindrical form. Its size, however, is probably less than it would have been 

 under more normal circumstances. The cone to the left seems to have its upper part 

 broken over. 



PL I. figs. 6, 6«, and 7,7a. 



Tlnse figures show two isolated bracts, with portions enlarged to illustrate the 

 delicate cilia which occur on the margins. These cilia are generally simple and more 

 numerous and longer on the expanded portion of the bract than on its upper region. 

 The bracts occasionally exhibit a slight keel, and are single nerved. 



PL I. fig. 8. 



This exhibits very beautifully the small thorn-like apiculi on the pedicel, not only 

 when seen from above, but also in profile at the margin of the pedicel. An enlarged 

 drawing is given at fig. 8a. These minute thorn-like structures are extremely numerous, 

 and occur on all the specimens which show the pedicel. In form and structure they 

 have tin- appearance of very minute thorns. On fig. 8 at b a fragment of one of the 

 bract-like leaves occurs. 



PL II. fig. 10. 



Here there is a tolerably complete cone, with portion of its pedicel. This has a faint 

 indication of ribs, but this may be due to a slight collapsing of the pedicel during 

 mineralisation, as it is absent from the other specimens. One of the bract-like leaves is 

 Been on the pedicel a short distance below the base of the cone.
