the middle genus Podocarpiuin. In the temporary assumption 

 that the Chalk species must be separated from the recent 

 species, I name the former Dacrydininm, while I designate a 

 Tertiary plant of New Zealand, which corresponds with the 

 living Dacrydium cupressinnm, as D. prcecupressinum . 



Gen. Ginl-gocladus. 



Bamnli secundarii plujllodinci ; plnjUodia loiuje pctiolata, 

 flahellato-innnatim nervosa, ncrvi omnes tenuissimi. 



As regards the pinnate-nerved lobate phyllodia, this genus 

 shows the habit of Pliyllodadus : as regards the very delicate 

 traversing nerves and the long petiole of the phyllodium, it 

 reminds one very much of Ginkgo.

 Plate XXX., fig. 19. 



G. pliyllodiis subcoriaceis, ovato-rJionibeis, lohatis, in 

 petiolmn longum decurrentibiis, lobis truncatis dentatis ; 

 nervo primario vix prominentc, nervis secuudariis et tertiariis 

 angulis acutissimis insertis, siniplicibns, craspedodromis.

The fossil leaf shown in fig. 19 might under superficial 

 inspection be mistaken for a frond of Asplcniuvi or Adiantum ; 

 however, under closer observation and comparison we must 

 come to the conclusion that this fossil could only belong to 

 the Taxinece, which carry phyllodia, and midway between 

 Phyllocladns and Ginkgo. 



The existence of a carbonized substance on the impression 

 indicates plainly a leathery texture ; but the charred deposit 

 is So thin that we may infer a delicate and yet leathery 

 nature such as belongs to the phyllodia -leaves of Ginkgo. 

 As regards the more pronounced rhomboidal shape, which 

 runs down the stem, the fossil is similar to the phyllodia of 

 Phyllocladns rliomboidalis, but there is a lobate formation 

 perceptible, which is similar to Ph. trichomanoides ; the 

 truncate lobes are at the front edge minutely, obtusely, and 

 unequally serrate. The comparatively long petiole is most 

 remarkable, as thereby the fossil approaches to the petiolate 

 phyllodia of Ph. rliomboidalis, but it comes even closer to the 

 long petiolate leaves of Ginkgo. 



We recognise in the nervation of the fossil described a 

 kind of combination of the nervation of Ginkgo biloba and of 

 Ph. trichomanoides. From the petiole, which is winged from 

 the descending lamina, starts a primary nerve, which is faint 

 at the base, and scarcely pronounced in its further course ; 

 from this primary nerve start already in the wiugs of the
