BKACHTPHYILTJM. 149 



V. 4688. Similar to 11,130 (PI. IX. Fig. 5), but larger and 

 more obscurely preserved. The leaf-areas are rather broader 

 and the apices of the leaves less prominent than in typical examples 

 of Thuifes expansus. Egerton Coll. 



Other specimens: — V. 3458 (Sevenhampton, Buchman Coll.); 

 V. 6586. 



Brachyphyllum, sp. j3. 



(PI. XII. Figs. 9, 9a.) 



In a paper On some Undescribed Coniferous Fruits from the 

 Secondary Rocks, Mr. Carruthers refers in an appendix ' to some 

 branches from the Oxford Clay of Chippenham, Cambridgeshire, and 

 Christian Malford, Wiltshire, and gives drawings of the specimens, 

 but he wisely refrains from appending names to the fossils. A small 

 piece of one of the specimens is shown in PI. XII. Fig. 9. Without 

 venturing to refer these coniferous fragments to a specific type, 

 they may be briefly described as possibly twigs of a Brachyphyllum. 

 The form of the polygonal leaf-areas agrees also with those on 

 branches of Cretaceous conifers placed in the genus Geinitzia ; but 

 the question of a generic name is unimportant, as we are unable 

 to refer the fossils with any degree of certainty to their family 

 position among the Coniterae. The vegetative twigs figured by 

 Saporta^ as Brachyphyllum nepos from the Kimeridgian and 

 Corallian bear a close resemblance to the English Oxford Clay 

 species.

Figured also by Carruthers (Gteol. Mag. vol. vi. pi. ii. fig. 12) 

 and by Schimper [Trait, pal. veg. pi. Ixxv. fig. 8 (copy of 

 Carruthers' figure)]. A carbonised stem 20-5 cm. long and 1'5 cm. 

 broad : the upper part is covered with carbonaceous polygonal 

 areas, in the centre of each of which is a prominent rounded 

 umbo ; a fairly well-marked median keel or ridge and a similar 

 transverse ridge extend across each polygonal area. In the lower
