NOTES AND EXHIBITS. 



Mr. Froggatt exhibited some remarkable Lepidopterous galls

 percentage that reach the moth-stage must be very small. How 

 the moth is ever able finally to emerge from a gall of the type

 the chalcid parasites hatched out, but died in the gall cavitv 

 being apparently unable to find a means of exit. 



Mr. Fred Turner exhibited — (1) Fruits of the Red Quandong 

 IFusaniis acuminatus R.Br.), with a basal elongation of the 

 pericarp, such as is sometimes seen in the Yellow Quandong 

 (var. chrysocarpus), but which he had not seen before in the 

 former; the specimens shown were forwarded by Mr, K. M. 

 Niall, Buckiinguy Station, Nyngan district.— (2) A specimen of 

 Trileleia tiuiflora Lindl., (syn. Milla iLuijlora Grab.), a Lilia- 

 ceous plant, a native of Buenos Ayres, sent to him by Mr. R. 

 Gowland, Pine Grove, Tooyal, Coolamon district, where it is 

 reported to be spreading, principally on rocky ground; it is a
