and partly imbricated, convex, broadly elliptical to subrhombic, and 

 slightly prolonged at their summits into acute tips. 



Locality: Entrance to Trent's Reach ; rare. 



These cones are found associated with the branches of Bracliyphyllum 

 crassicaule. They may belong to this species, or to some other conifer. 

 They agree pretty well in shape with the macerated cone given in PI. 

 CIX, Fig. 6. It is obviously a cone of the same type with those described 

 by Saporta as associated with the French specimens of BracliyphyUum. It 

 agrees best with the cones of B. gracUe^ Brongniart, but does not seem to 

 be identical with them. 



Brachyphyllum, sp. ? (Cone.) 



Plate CXXXV, Fig. 9. 



Cone small, broadly oblong ? , length not made out, as the basal por- 

 tion is wanting, width 10"""; scales numerous, closely appressed, partly 

 imbricated, spirally arranged, thick and convex, in shape broadly elliptical 

 to subrhombic, acute at the tips. 



Locality : Entrance to Trent's Reach. 



These cones occur with those of the preceding species and are more 

 common than the latter. They seem to belong to a distinct species. In 

 the rounded shape and in the size they come nearer than any of the pre- 

 viously described ones to what Saporta thought was the male ament of B. 

 (jracile Brong. It resembles in some points tliat shown in Pal. Franqaise, 

 V(ig(;taux, vol. 3, PI. CLXXI, Fig. 9. It may be the male ament of B. cras- 

 sicaule, although apparently rather large for that. 



Brachyphyllum, sp.? (Cone.) 



Plate CLXVIII, Fig. 2. 



This is a small fragment of a cone found at the entrance to Trent's 

 Reach with the two last-described species. It is too imperfect to admit of 

 description, the margins being in no place preserved, and the surface show- 

 ing only subrhombic scars with depressed points in the center. These 

 scars seem to be those left by the scales of the cones.
