is usually considérée! its most characteristic organ. For example it will 

 be Seen that the operculum of var. sqiiamosa is conical and even hemi- 

 splierical, a similar tendency is shown in vai-. dealhata and esj)ecia]ly in 

 those forms which extend into the far interior and which, I think, 

 cannot be differentiated from E. rosirata growing in those régions. The 

 variety has a peculiar glaucous appearance unique among the Eucalypts 

 in the districts in which it grows; this appearance is also to be observed 

 in interior tbrms of E. iereticornis. 



The timber of var. squainosa does not appear to difter in any rospect 

 from that of other sw^amp loving forms of E. tereticornis. 



RANGE 



The ibllowiug localities where E. tereticornis is found range from 

 Gippsland (eastern Victoria) in the South, along New South Wales 

 (extending several hundreds of miles into the interior), and Queensland, 

 into New Guinea, being one of the few species of the genus which occurs 

 beyond Australia and Tasmauia. These localities are of course not 

 exhaustive, but they give a good idea of the distribution. Other loca- 

 lities have been given under the respective varieties. Under some of the 

 localities notes are given in regard to particular trees. 



VICTORIA 



Metung, Gippsland (A, W. Howitt). The Victorian form of the species 

 is quite normal. M"" Howitt states that E. tereticornis is coufined almost 

 entirely to that part of Victoria; he has only observed it elsewhere in 

 the extreme north-eastern district. He also observes that the forests of 

 this species in Gippsland have suffered for thirty years from the attacks 

 of larvœ of a moth which devour the Upper and under surfaces of the 

 leaves and thus ultimately kill the tree. 



« Whole forests for instance at Nimbin and Lindenow have within 

 my knowledge been thus killed ». 



Similar attacks on this species have been observed in coastal New^ 

 South Wales.
