308 DESCRIPTIVE CATALOGUE 



V. 9383. Figured, text-fig. 97. A specimen showing the ex- 

 ternal appearance of the leaf-bases very well, as is 

 illustrated in the photograph (text-fig. 97). 



A similar piece, still in the Botanical Dept., appears 

 to belong to the same trunk. 



"Potton Sands," Lower Greensand ; near Leighton Buzzard. 

 Transferred from the Botanical Dept., 1903. 



V. 6602. A block, 20 cm. long and 8 cm. in diameter, con- 

 sisting principally of pith-cast, but with a portion of 

 two wood-rings and a few fragments of leaf-bases on 

 one side of it. It shows 110 features not better pre- 

 served in other examples of the species. 



V. 5266. A small fragment showing three or four leaf-bases, 

 and part of the two wood-rings. 



" Potton Sands," Lower Greensand ; near Leighton Buzzard. 

 Transferred f i om the Botanical Dept., 1898. 



V. 221. Two fragments (9x4 cm. and 7x4 cm.) showing some 

 rather irregular leaf-bases and portions of the two 

 wood-rings clearly weathered out. " Potton Sands," 

 Lower Greenland ; near Leighton Buzzard. 



JUon-is Coll, 1883. 



V. 5267. Probably to be included in the species Cycadcoldea 

 Tatesii is a small fragment with much smaller leaf- 

 bases than in the rest of the specimens. Save for the 

 smaller-sized leaf-bases, there seems to be no other 

 difference between this specimen and the others de- 

 scribed above; two wood-rings can be clearly seen and 

 the pith-cast is similar to the others. " Potton Sands," 

 Lower Greensand ; near Leighton Buzzard. 



Transferred from the Botanical Dept., 1898. 



47049. Figured, text-fig. 94. The surface-view shows rather 

 irregular leaf-bases, within which the two rings of 

 wood are clearly seen weathered out at one end of the 

 broken surface. Within this is the large hollow of 

 the pith, the surface cast of which (equivalent to Ihe
