June 27th, 1894. (Schluß.) Mr. Pedley showed an interesting collection 

 of ornately carved Aboriginal weapons comprising boomerangs, nullah nullahs 

 and a hielaman, from the neighbourhood of Angledool and Collarenebri in 

 the north-western part of the colony. — Mr. Froggatt exhibited speci- 

 mens of the moths mentioned in his paper ; a section of the stem of an Aca- 

 cia attacked by Eudoxyla eucalypti; the felted bags formed by the larger 

 variety of this species, and tlie wads formed by Leto Stacyi. — Dr. Cox 

 showed a beautiful specimen of a lamellibranch [Mactra] , obtained by Mr. 

 Massie at the White Cliffs, near Wilcannia, the calcareous matter of the 

 valves of which had been partly replaced by precious opal. He also exhi- 

 bited an elaborately ornamented specimen of a form of boomerang club, one 

 of several he had recently seen , procured from the Pitchery country, to the 

 north or north-east of Bourke, in Queensland. Associated with this weapon, 

 received by Mr. Rankin from a squatter, were some dozen or more fine 

 boomerangs, all of them elaborately ornamented with carvings, and three 

 wooden spears, about 18 feet or more long, each made from a single piece 

 of wood , evidently for use without a womerah ; these likewise are orna- 

 mented from end to end with longitudinal carving as if in imitation of a 

 climbing plant. There were also three fine shields. The collection was of 

 so much interest. Dr. Cox said, that he hoped to be able to exhibit it in its 

 entirety at the next Meeting. — Professor David exhibited some specimens 

 of the Silurian coral Mticop/tyllum from the Yass District, with numerous 

 small siliceous fossils , probably siliceous sponges , attached chiefly to the 

 under-surface of the coral. The siliceous skeleton as seen under the micro- 

 scope is minutely spicular. In most of the specimens the original organic 

 structure of the silica has been obliterated through the alteration of the silica 

 into the chalcedonic variety of quartz, beekite.
