■ItKyiDENT S ADDRESS. 



vai'ious gaps require to be tilled, a task that will take many months, for, unlike 

 the seacoast wbere the sword gi-ass is fairly continuous, in the mountains it oc- 

 curs in small isolated patches more paa-ticularly at the higher elevations. 



In conclusion, other than those already mentioned, I have to thank Mr. C. 

 Hedley for many suggestions over a number of years and our Secretary Dr. 

 Walkom who has been of great assistancei to me all tlirough the last year. 



In illustration of his remarks Mr. Waterhouse exhibited a case of butterflies 

 showing all the subspecies of T. abeona with a map giving their distribution; a 

 case containing about 80 specimens of joanna from Port Macquarie showing all 

 the general types of variation so far caught; a case showing the parents and two 

 large families of hybrids of the first generation, one having abeona as the male 

 parent and the other morris! as the male parent, also all the second and third 

 generation hybrids obtained; a case showing the preliminary experiments with 

 abeona and rawnsleyi and all the hybrids obtained.
