578 NOTES AND EXHIBITS. 



21st inst. It is of the usual cup-shaped form and is constructed 

 almost entirely of white fowl feathers and white cow-hair, 

 matted and held together with fine strips of bark-fibre and a few 

 pieces of string. The nest, which measures exteriorly 21 inches 

 in diameter by 31 inches, was found close to a poultry farm, and 

 contained two young birds just able to fly. 



Mr. Musson contributed a Note on the trimorphic character of 

 AnguiUaria clioica, R.Br. One thousand specimens of this vari- 

 able plant (all those growing on six square yards) were pulled up 

 a,nd sorted. Of these, 26 (or 2-6 per cent.) were polygamous ; 

 510(51 percent.) had potentially male flowers only, the pistils 

 being rudimentary; and 464 (46-4 per cent) had female flowers 

 only without indication of even rudimentary stamens. Other 

 peculiarities furnished by these specimens were also noted. As 

 the species occurs in all the Australian Colonies -it would be of 

 interest if observers elsewhere would tabulate their experiences. 

 Sufficient data might thus be accumulated for satisfactory 

 generalisation, as AnguiUaria. like Fittosporum nndiiJatum, 

 seems to be in an advanced stage of transition towards complete 

 separation of the sexes. 



Dr. Cox exhibited, in illustration of Lieutenant Beddome's 

 paper, specimens of GijprcBa subcarnea, Ancey, and var., C. 

 declivis, Sowb., C. angustata, Gray, and vars., C. comjitoni, Gray, 

 and vars., and Trivia australis. 



Mr. Fletcher exhibited some hymenopterous insects (Fam. 

 Thynnidce) forwarded last week by Mr. C. F. Bolton of 

 IVIoorong, Wagga, as a sample of myriads closely clustered on the 

 wires of his vineyai'd fence. They were thickest in one spot 

 where the clustering swarms extended over a distance of about 

 five feet on each of three wires — one above another. The insects 

 evidently had recently emerged from their underground cocoons. 

 Possibly on account of the mild winter they had made an 

 appearance earlier than usual and in advance of the flowers. A 

 week later some swarms were still to be seen on the wires.
