Plate VI., fig. 11 (342c). 



A curved piece of rachis slightly enlarged, the actual length being 

 4-5 cm. In the lower part a portion of a longitudinally striated 

 woody axis is exposed ; the stout woody character of the rachis is 

 shown in the outline of a transverse section to the left of the figure. 

 The two lowest pinnse rest obliquely on the axis. Against the base- 

 of the third pinna the surface of the woody axis is covered with 

 a thin piece of rock which represents the remains of a cushion ; 

 a larger and more distinct portion of cushion is seen at c, and at d 

 the outline of a partially preserved cushion is more distinctly seen. 

 The position of the pinna to the left of the axis at d shows that the 

 pinnae abutted on to the side of the cushions. A more clearly 

 defined cushion is seen at c, but at h the surface-features are 

 still better preserved. From the upper end of the specimen the 

 cushions are absent, but the transversely elongated depression is 

 seen at a. 



Plate VI., fig. 12 (286c). 



Flattened rachis showing on one side the attachment of a row 

 of pinnae and on the other the oblique oval scars to which the 

 pinnae were articulated. 



OtJier Sjyecimcns : 255c, portions of two fronds approximately 

 parallel to one another, with fragments of others A piece of a 

 rachis or petiole, 7 mm. broad, occurs on this slab of rock which 

 no doubt belongs to Zamites recta. The longest piece of frond is 

 18 cm. long, and shows that the whole leaf was probably at least 

 40-50 cm. in length; 259c, 260c, 264c, a piece of a frond about 

 30 cm. long, with other fragments. The small amount of difference 

 in the position and size of the pinnae at the two ends points to a 

 frond of considerable length. On the under surface of the rock 

 there is a cast of a stem with surface features similar to Benstedtia. 

 302c, 303c, 345c, 352c. 279c, similar to some examples of Zamites 

 buchianus (Ett.),* but differing from that species in the form 

 of the base of the pinnae. Segments of Araucaritcs scales occur 

 on the reverse side. 323c, with the impression of a stem (?) 

 giving off" several narrow roots. 334c, with Araucaritcs scales,, 

 346c, 372c.
