to the rachis, it is probable that this large example may 

 represent a frond not quite fully developed. The stout rachis, 

 about l - 4 cm. in breadth, and especially that of the smaller 

 frond, shows numerous obliquely running longitudinal lines. 

 The contiguous and slightly broadened bases of the pinnae are 

 very distinct on portions of the larger frond. In some places 

 the segments, adhering together by their contiguous bases, have 

 been torn en masse from the axis of the leaf. 



The stout and distinct median vein is well marked throughout.

V. 2797. PL VI. Pigs 5 and 5a. 



Frond 13'5 cm. in length; rachis I cm. broad. The long and 

 contiguous pinnae are attached at right angles to one edge of 

 the flattened axes. Midrib distinctly preserved, as in Fig. 5a ; 

 also the sharply acuminate tips of the segments. Longest pinna 

 11 cm. The general appearance of this specimen is indicative 

 of an older frond than V. 2777. Ecclesbourne. Rufford Coll.

24 cm. long. At the two extreme ends only one row of 

 pinnae has been preserved, and the impression of the broad rachis 

 is shown on the surface of the rock. In other places the two 

 rows of pinnae are almost in contact, as in the portion repre- 

 sented in PL IV. Fig. 5, and there is very little of the rachis 

 visible between the bases of the two sets of pinnae. The 

 arrangement and general appearance of the segments bear a 

 marked resemblance to Dioonites D linker ianus (Gb'pp.). Eccles- 

 bourne. Rufford Coll. 



V. 1069. A more terminal portion of a frond. Pinnae smaller 

 and more obliquely inclined to the rachis than in most of the 

 other specimens. Cf. the terminal portion with the specimen 

 of Dioonites Dunkerianus (V. 2823) figured in PL II. Fig. 3. 

 Ecclesbourne. Presented by P. Ritffvrd, Esq., 1885. 



V. 2124. Narrow pinnae attached to one side of the flat rachis. 



V. 21245. Several portions of fronds. In one there appears 

 to be the broad and thick basal termination of the petiole fairly
