194 NOTES AND EXHIBITS. 



this is probably to be found in its more or less complete adoption 

 of a diurnal habit necessitated by the coldness of the nights, in a 

 region where trees (and consequently fallen leaves, chips and logs) 

 are absent, and grass, herbaceous plants and dwarf shrubs make 

 up the vegetation, cover being afforded by boulders, crevices, &c. 



Mr. Fletcher exhibited also specimens of Heleioporus pictus, 

 Ptrs., from West Australia, part of a collection made by Mr. A. 

 M. Lea, "within 100 miles of Perth." This species is an addition 

 to the Batrachian fauna of West Australia, and is evidently a 

 widely dispersed and characteristic member of the fauna of the 

 Eyrean Sub-i'egion. 



Mr. Musson exhibited a clump of the woody galls of the 

 Brachyscelid G ijlindrococcus spiniferits, Mask., on Casuarina 

 saberosa, gathered at Richmond, which had been forcibly broken 

 open, presumably by predaceous birds for the purpose of extract- 

 ing the enclosed coccid. Also specimens of four indigenous 

 grasses affected with parasitic fungi, gathered at Richmond, not 

 included in the list of affected species given by Mr. Fred. Turner 

 (Proceedings, 1897, p. 6S6), namely, Anthistira ciiiata, L., 

 Andropogon refractns, R.Br., Panicum pygnueum, R.Br., and 

 Soryhum. phimosrttn, Beauv.
