NO. 3.] DESCRIPTION OF SPECIES. 21 



Carpolithes sp. b. 

 PI. II. figs. 40 and 40a (magnified). 



This may be the seed of Taxites or Ginkgo, but may even be a wingless 

 Pityospermuni, or one where the wing has fallen off. 



Carpolithes sp. c. 

 PI. II. figs. 41 and 41a (magnified). 



An oval seed, striated, (fig. 41a). It is possible that it may be a Pityo- 

 spermum without wings. 



Carpolithes sp. d. 

 PI. II. fig. 42 (twice magnified). 



Two seeds, not unlike the preceding though more acute, are here fixed 

 at the side of each other. It may be considered that they are impressions 

 of two Pinus seeds affixed to the scale of cone. 



Carpolithes sp. e. 



The cast of a seed represented in the accompanying letterpress-figure (fig. 5) 



has on the whole a heart-like form though with a truncate base. In the centre 



there is a deep impression or cavity, and the apex ap- 



m\ (^ pears cleft. Thus it bears a faint resemblance to certain 



Samaropsis-iorms from Eastern Siberia described by 



^'S- ^- Heer, without, however, any complete agreement with 



Carpolithes sp. e. 



natural size and any of them, 

 magnified. 



INGERTAE SEDIS. 

 Fig. 6. 

 The object here represented (fig. 6) is probably an inflorescence of some 

 conifer. As, however, it may be also compared with twigs, I have thought 

 it wiser to enter the fossil as incertae sedis. The cylin- 

 drical objects lying beside and above one another, on 

 ^0g the surface, present a sculpture (badly represented in the 

 figure) which seems to indicate that they have been 

 constructed of small, closely packed scales. If, on the 

 Incertae sedis. other hand, the objects be considered twigs, the sculp- 

 tuie would be derived from leaf-scars.
