hollows under the feet and the spaces between the toes. Dogs 

 are often lamed by the irritation caused by the presence of seeds 

 in the situations named. As these animals often travel great 

 distances with shepherds and drovers, there is at any rate the 

 possibility that they play some part in carrying seeds, even 

 though it may be granted they do but little. 



The spores of Nitella^ Spirogyra, &c., may be transported by 

 wind, but more likely adhering to the legs and noses of animals, 

 or on the feet and feathers of aquatic birds, as wild ducks, 

 grebes, cranes, &c. 



III. The Plants from Adelaide District, &c. 



It may be contended, and with much force, that these species 

 were introduced among seeds brought here by settlers, as vege- 

 table seeds, flower seeds, wheat, oats, &c. In many cases this is 

 almost a certainty, and may be taken as such in species like 

 Bm-'harea, Kennedy a prostrata, Urtica incisa, &c., but I do not 

 think the above explanation can apply to Callitris cupressi/ormis, 

 Choretrurn spicatum, Casuarina quadrivalvis, Pterostylis pedunau- 

 lata, Xanthorrhcea quadrangulata, Lindscea linearis, Arundo, 

 (fee. Does not the presence of these plants point to the proba- 

 bility of a period when the Euronotian region ran well up the 

 Flinders Range, when climatic conditions were different and 

 better — perhaps in the early or middle tertiary periods ? 



In conclusion, I would again repeat that this paper consists of 

 Notes, and must not be taken as more than the briefest statement 

 of the points touched upon. I feel and know that much remains 

 to be done in this locality, not only as regards its botany, but on 

 other lines also ; and I venture to express the hope that while 

 tracts of untouched land remain — and that apparently will not 

 be for many years longer — this Society will find workers willing 

 to complete what is thus begun.
