broad character of the cone is a point in favour of a comparison with 

 such small, presumably female, cones as those of the Wealden 

 Splienolcpidium sternhcrgianuvi (Schenk),''' Ceratostrobus echinatus 

 Vel.,f of Lower Cretaceous age, and some small cones described by 

 Fontaine from the Potomac formation:!: as " aments of conifers." 

 The cone-scales as shown in fig. 2a are imperfectly preserved, but 

 there aref indications of a central keel or projection on their 

 ■expanded distal ends. 



CONITES Sp. /3. 



Plate VI., figs. 1, la, 3. 



These cones may be specifically identical with the slightly broader 

 form represented in fig. 2, but their relatively longer and narrow 

 form suggests that they are male flowers. 



Plate VI., figs. 1, la (253c). 



The cone represented natural size in fig. 1 shows numerous 

 spirally disposed, distally expanded scales with traces of a small 

 central umbo (fig. la), which may well be sporophylls bearing 

 pollen-sacs. 



Plate VI., fig. 3 (298c). 



A cone seen in longitudinal section, showing the sporophylls 

 attached at right angles to the axis of the flower.

CONIFEEOUS WOOD. 



In addition to the stem casts referred to the genus Benstcdtia, the 

 collection includes a few specimens of what is probably true coni- 

 ferous wood ; but without petrified examples it is impossible to 

 attempt an accurate determination. 



Specimen x. Tliis specimen represents a sandstone cast, 19 cm. 

 long, and at least 8 cm. in diameter. The contour of the surface is 

 the chief point of interest ; the wood of the stem or root was con-
