616 Edwards. — Fossil Coniferous Wood from Kerguelen Island. 
These, however, are probably not constant specific characters. Another 
Tertiary species, Dadoxylon Doeringii (Conwentz), from the Oligocene of 
Patagonia (Conwentz, 1884 , p. 448), is not so closely related, for it has much 
higher and occasionally biseriate rays. 
Summary. 
An examination of fossil wood from Kerguelen Island in the British 
Museum (Natural History) has revealed the presence of only two species 
(apart from some rather doubtful dicotyledonous wood), the anatomy of 
which is described in detail. In the case of Cupressinoxylon antarcticum , 
Beust, the preservation of the minuter features does not permit of an exact 
comparison with recent genera. 
The other species, Dadoxylon kerguelense , Seward, closely resembles 
the wood of living araucarians, and has well -developed resin spools or plates 
in the tracheides. 
These fossils do not give sufficient indication of the precise age of the 
basalts beneath which they were found, and which are generally regarded 
as being of Tertiary, and perhaps early Tertiary, date.
