to lie between 2 mg and 5,5 mg per kilogram of body-weight. For Hyla 

 aurea the minimal lethal dose is 0,1 mg per gram of body-weight, and is 

 somewhat higher in frogs collected in winter than in those collected in 

 summer; but is unaffected by differences in sex. The receptive substance of 

 the muscles of Hyla aurea is sensitive' to strychnine, so that the frogs show, 

 with appropriate doses, typical curare paralysis. The prominence of this 

 action produces a characteristic type of poisoning in Hyla. — (3) A Contri- 

 bution to our Knowledge of Australian H ir u din e a. Part I. By E. J. Goddard, 

 13. A., B.Sc, Junior Demonstrator in Biology, University of Sydney. — Two 

 species of freshwaterleeches referable to the genus Glossiphotiia[syn. Clepsme : 

 Farn. Glossiphonida e] from New South Wales are described as new — the 

 first record of the genus in Australasia, it is believed; and a new genus is 

 proposed for a remarkable species, also a freshwater form, obtained by Dr. J. 

 P. Hill near Oberon, N.S.W.

 Medical School), or by such specialists as they may choose. The Association 

 reserves the right to withhold the award of the prize, if the theses presented
