110 NOTES AND EXHIBITS. 



hybrid from Acacia Bailey ana $ and A. deeurrens var. mollis 9; 

 Mr. H. L. White, of Belltrees, Scone, found this form in his 

 garden, under a tree of the latter; the hybrid exhibits characters 

 almost strictly intermediate between the two species. 



Dr. D'Ombrain showed portion of a plank of Oregon Pine 

 showing the ravages caused by a molluscan marine Wood-borer 

 (Nausitoria saulii Wright) during immersion in the waters of 

 Sydney Harbour. 



Mr. McCulloch exhibited a freshwater turtle taken in the salt 

 water of the Parramatta River during dry weather, when the 

 ponds had dried up; on being restored to fresh water, the animal 

 seemed indifferent to the change. 



Mr. A. A. Hamilton showed specimens of two introduced 

 plants from the National Herbarium, which, he believed, had not 

 previously been recorded from New South Wales, nor the first 

 from Australia — Paronychia chilensis DC, (near Melbourne, H. 

 B. Williamson ; Randwick, Sydney, A. A. Hamilton) ; and 

 Caucalis nodosa Scop.,(Inverell, E. S. Thomas). Also a specimen 

 of Leucopogon appressus R.Br., a rare plant in New South Wales 

 (Cheltenham, Ryde-Hornsby; E. Cheel). 



Mr. E. Cheel exhibited an interesting series of specimens of 

 species of Eragrostis represented in the National Herbarium col- 

 lection, and invited special attention to the remarkable similarity 

 of the morphological characters, which causes considerable diffi- 

 culty in determining the various species, as will be seen from 

 observations offered in connection with the respective species. 

 Eragrostis pilosa Beauv. : Waterworks, Brisbane, Q. (J. L. 

 Boorman). These are the only Australian specimens represented 

 in the collection. There are, however, several sheets of speci- 

 mens from New Caledonia, India, and South Africa, which are 

 identical with the Queensland specimen quoted above, as will be 

 seen by comparing the specimens with E. pilosa from Natal, S. 

 Africa, distributed by J. Medley Wood, No. 6058. This seems 

 to be chiefly confined to the warmer regions, and is everywhere 

 regarded as a common weed, and of no value as a fodder-grass. 

 It is interesting to note, that the Queensland specimen shows the
