Anotlier reason for referring the present specimen to the genus 

 or type of Araucarioxylon is the absence of resin cells in the 

 medullary rays and among the vertical tracheides. 



It differs from the Cedroxylon type of coniferous wood — to 

 which it otherwise bears most resemblance — not only in the 

 above feature, but also in having the medullary rays, as seen in 

 transverse section, more widely separated, and also in having the 

 bordered pits of the radial walls of the tracheides disposed in 

 several rows, instead of singly, as seems to be the general, though 

 not invariable, rule in Cedroxylon 



Enough has probably been said, having regard to the limited 

 material at present at our disposal, upon the claims of the 

 abo\e to be regarded as a typical Araucarioxylon. This has 

 been already done by Carruthers^ and Etheridge, Jun.," for 

 tlie fossil wood found in the Bowen River formation ; but these 

 authors liave unfortunately given no figures or description of 

 any definite specimen, so that the name by which the fossil wood 

 from Queensland was previously recorded must now lapse, as 

 Mr. Etheridge himself suggests when recording the fossil wood 

 occurrences.'^ 'I'he diagnosis now given will, it is hoped, 

 strengthen the claim of the Conifers to be considered as having 

 existed indubitably in Carboniferous times.
