PROCEEDINGS OF BIOLOGY SECTION. 



Proceedings of Biology Section. 



Meeting, .September 8th, 1914. 



Dr. J. Shirley in the chair. 



Six members present. 



Dr. Shirley exhibited specimens of the '• Grey Gum " of 

 Queensland, and pointed out that the Queensland Grey 

 Gum, though usually set down as E. saligna does not agree 

 with the description of the species given in Miiller's Eucalypts 

 of Australia. It is probable that the tree referred to by 

 Queensland botanists as E. botryoides. Smith, is the true 

 E. saligna. Among the specimens supplied to Dr. Shirley 

 as examples of Grey Gum, from various parts of Queens- 

 land were : — E. melliodora, E. baueriana, and E. propinqua . 



Most of those present took part in a discussion of 

 the fruits, leaves, etc., Mr. Smith pointing out the relation 

 existing between the type of venation and the kind of 

 products obtained from Eucalyptus leaves. 



Meeting, October 13th, 1914. 



Dr. J. Shirley in the chair. 



Three members and one visitor present. 



Dr. Shirley exhibited specimens of several different 

 species of Chitons, a group belonging to the class Amphi- 

 neura of the MoUusca. He then gave a short description 

 of their distribution and general anatomy, illustrated by 

 reference to the specimens. 



The chairman pointed out that the group is not a typical 

 Molluscan one, especially in regard to its nervous system, 

 which is simple. Some discussion ensued as to whether 

 this signified a primitive or a degenerate form, Dr. Shirle}' 

 inclining to the former view.
