210 NOTES AND EXUIBIT.S. 



pears as a weed iu other parts of the world. It has the general appearance of A. 

 macrocarpufi Henth., a native species, from which it differs in the mostly terminal, 

 slender paniculate inflorescence, and in the relatively smooth pericarp. Professor 

 Ewart (Proc. Roy. Soc. Vic, xx.xii., 1920, 19(1) records it for Victoria. (2). 

 Xanthium commune Britt., the "Common Cockleburi-" of America, which wa.s 

 recently forwarded for identification by Mr. C. A. Horning, of Ebenezer. (_)n 

 mvestigation two other specimens were found under X. strumarium the "Noogoora 

 Burr'", namely from Cattai near Windsor (V. C. Giles. 1915), and near Dunedoo 

 (M. Beahan, 1918), thus indicating that this obnoxious plant is spreading un- 

 noticed. The new burr is similar in habit to the "Noogoora," but is readily dis- 

 tinguished from it by the more ovate, densely uncinate pubescent burrs. As far 

 as can be ascertained, it is new for the Commonwealth. 



Mr. Blakely also exhibited fresh specimens of Euphorbia Drummo)idii Boiss., 

 from Barellan (T. A. Field), with the leaves, flowers, and fruits infested with 

 bright pink galls, which gave the idant a striking lloral appearance. It is not 

 known what physiological change tlie galls would impart to the plant, or whether 

 they would be injurious to gi'azing animals. 



Mr. A. S. Le Souef exhibited a live s])ecimen of Moloch horridus from Ooldea, 

 where it is numerous on the sandhills on which it lays its eggs. A clutch of 

 eight eggs wa.s found in Dec«niVjer last. These lizards feed on small black ants. 



Dr. E. W. F'ergiison exhibited a series of ten species of Tabaiiidae forwarded 

 from the British Museum as exchanges. 



Dr. A. B. Walkom exhibited a specimen, probably the flower of a Mesozoic 

 Cycadeoid, from the Triassic Kocks of Ipswich. (Queensland. 



The President asked members to hand notice of their intention to exhibit to 

 the Secretary before the commencement ol' each meeting, in order to facilitate 

 the business.
