1 1 . Rhipicephahis annulatus, Say, var. australis, Neum., a 

 Queensland Cattle Tick. Hob —The Island of Neui, off New 

 Britain (upon cattle said to have been shipped original 1}' from 

 Cook town to New Caledonia, and thence to Neui, according to 

 information supplied by the sender of the specimens.) 



12. Argas americanus, Packard, the Fowl Tick. Hab. — 

 Various localities (upon fowls). 



Of the above, Nos. 8, 10, and 11 were previously undescribed; and with the 

 exception of No. 11 all the specimens were collected in New South Wales. 



Mr. C. W. Darley exhibited a portion of the timbers of a punt, 

 showing the depredations of an Isopod which had been deter- 

 mined by the authorities of the Australian Museum to be the 

 destructive " Gribble," Limnoria lignorum, Rathke ( = L. tere- 

 brans, Leach), not previously recorded from Australian waters, 

 and therefore presumably introduced from Europe or America. 



Mr. Stead exhibited an ant (Iridomyrmex purpureus), and a 

 piece of quartz, relatively much bulkier than the animal, which it 

 been observed to lift bodily. 



Mr. Palmer exhibited a very perfect cast skin of a snake from 

 the Blue Mountains. 



Mr. Trebeck showed a good specimen of the rattle of Crotalus 

 sp., from British Columbia. 



Mr. Fred. Turner sent for exhibition a specimen of the grass 

 Eragrostis nigra, Nees, var. trachycarpa, from near Armidale, 

 N.S.W., with the inflorescence infested with a parasitic fungus — 

 the first instance of this valuable pasture grass in this condition 

 known to him. (For records of twenty other species similarly 

 affected, see Proceedings, 1897, p. 68G, and 1899, p. 19-1.) Also 

 a variegated form of Kennedya rubicunda, Vent., collected at 

 Pennant Hills, near Sydney, in January last, which had not pre- 

 viously come under his notice, though the species is common and 

 widely distributed.
