of the pinnre ; on one side there are nine pinnae, and on the 

 other seven. These show the broad, obtusely terminated form of 

 the segments very clearly ; they are attached to the upper surface 

 of the rachis by the central portion of the distinctly auriculate 

 base. Most of the pinnae overlap, the upper edge of each pro- 

 jecting over the lower margin of the pinna next above it ; very 

 similar in habit to some of the larger specimens of 0. Beanii in 

 the Leckenby Collection. On the under side of the same slab 

 there occur portions of pinnae of another frond, and a section of 

 a rachis mould, about 6 mm. broad and 8 mm. in depth ; also 

 a specimen of Cycadites Saportce, sp. nov. Ecclesbourne.

V. 2122^. PL VII. Fig. 2. Rachis imperfectly preserved ; 

 portions of six pinnae, the uppermost having the same form as 

 the largest of V. 2745 (PL I. Fig. 4), the lowest and largest, 

 6-4 X 3 cm. (PL VII. Fig. 2), showing a slight lobe in the middle 

 of the upper margin. In some of the segments the point of 

 attachment is well shown, and the numerous fine spreading 

 veins are well marked in the carbonaceous surface layer. 



V. 2126fl. PL VII. Figs. 4 and 8. Frond 28cm. long.; 11 

 pinnae on one side. Hollow round mould of rachis, about 4-5 mm. 

 in diameter. Short and broad overlapping pinnae, 4'8 X 2'5 cm., 

 and very like those of V. 2740tf, V. 2740, etc. The upper and 

 smaller pinna?, as shown in the figure, are narrower and longer 

 and not overlapping ; these agree exactly with the segments in 

 V. 27450 (PL I. Fig. 4). Uppermost pinnae about 3 cm. x 1*8 cm. ; 

 a segment separated from this by 1 1 cm. and attached to about the 

 middle of the specimen, measures 4 - 5 X 2'5 cm. The two larger 

 pinnae (PL VII. Fig. 8) agree very closely with those of V. 2170 

 (PL VII. Fig. 9) ; they have a strongly convex upper surface, 

 and show a sharp bending down of the lamina near the point 

 of insertion to the rachis. This bending of the pinna base is 

 exactly similar to the appearance frequently presented by the 

 stiff leathery pinnae of recent species of Encephalartos, to which 

 allusion has been made in the introductory remarks on fossil 

 Cycadacea. 



V. 2126. 32 em. long. Rachis about 4mm. broad, in the form 

 of a round hollow mould. Compare the largest pinna of this 

 specimen with the smallest of V. 2122.
