]!fOTES AND EXHIBITS. 329 



Wilkinsoni, ^hymatocaryon Machayi, P. angular e, Penteune 

 GlarJcei, Spondylostrohus Smithii, &c. Mr. Wilkinson explained 

 by a rough section the geological structure of the locality : An 

 old valley in the Silurian rocks, with its bottom of auriferous 

 drift, in which the specimens were found, had been filled up by a 

 flow of basalt from the neighbourhood of the Canobola Mountain, 

 through which the shaft above mentioned is sunk to the bed rock. 



Dr. Cox exhibited in addition, a stone hatchet, obtained from 

 Kane's Paddocks by Mr. Newton, jun. This hatchet differs 

 from those usually found in not being made from a smooth water- 

 worn pebble, but from a piece of metamorphic rock, which has 

 been split and chipped so as to resemble the ordinary waterworn 

 stone hatchets. 



Mr. T. Tenison-Woods exhibited a drawing of impressions 

 of the " red hands," made by the aborigines in a rocky recess in 

 the Mudgee district. This peculiar symbol, the exact meaning 

 of which was unknown, existed among all the tribes throughout 

 the whole of Australia. The speciality of this exhibit was that 

 the impression consisted of both hands, left and right, the right 

 hand impression being usually the only one made. Mr. Tenison- 

 Woods stated that he hoped to furnish the Society at a future 

 date with further observations on this practice of the aborigines. 

 Dr. Cox described the manner in which the impressions were 

 made. 



The Hon. W. Macleay, T.L.S., exhibited some grape vine 

 cuttings much eaten by the larva of a weevil. He said that he 

 had received these cuttings from Mr. A. T. Holroyd, whose 

 gardener had discovered, in pruning his vines, that a large 

 number of them had been attacked in this way. The larva is a 

 small white, fleshy, curved, apod grub, evidently of the weevil 

 tribe, which commences its ravages at or near the extremities of 

 the young shoots of the vine, and works its way towards and 

 even into the old timber and roots of the plant, eating away the
