of these larger pinnules resembles that of some of the longer fertile 

 segments of Todites Williamsoni. 



39,230. Text-fig. 22. 



A large specimen, but not very clearly preserved. The figured 

 portion is from the apical region of a pinna, and illustrates the 

 gradual decrease in size of the pinnules towards the apex of one 

 of the long pinnse. The specimen shows clearly the characteristic 

 open habit of the frond; long and narrow pinnee, 13cm. long, are 

 attached at right angles to a slender rachis ; the pinnse have an 

 average breadth of about 1 cm., and bear fairly closely set pinnules 

 of the form shown in Fig. 21 (39,257). Those pionse in which 

 the preservation is best, show the broad basal pinnule on the lower

side of the pinna where it is attached to the rachis. Cf. this- 

 specimen with the figures of Lindley & Hutton (pi. clxxix.) and 

 Eaciborski (pi. xi. fig. 1). The form of the pinnae and pinnules- 

 is in close agreement also with that of Nev/ropteris undulata, 

 L. & H. (pi. Ixxxiii.).

V. 3653. PL XV. Fig. 6. 



A similar specimen to 39,230 (Fig. 22) and to the type of 

 Lindley & Hutton. The portion of the specimen represented in 

 the figure illustrates the long, naiTow, and spreading pinnae, and 

 the elongated deltoid form of the pinnules. The lower pinna in 

 Fig. 6, PI. XV. shows the large basal pinnule immediately below 

 the point of attachment of the pinna to the rachis.
