NOTES AND EXHIBITS. 



Mr. W. S. Dun exhibited a well preserved specimen of the 

 coalesced basal plates of Phialocriiius Konincki, collected at Mt. 

 Vincent, in the Upper Marine Stage of the Permo-Carboniferous. 

 The specimen is interesting from the fact that on the inner sur- 

 face it shows the well-marked junction of the five basal plates, a 

 structure that is not visible on the outer aspect. This is a point 

 that has not been observed before. The specimen was collected 

 b}^ Mr. Eustace Wilkinson. 



Mr. Gurney shov/ed 'three living specimens (9) of Extatosoma 

 tlaratum, W. S. Macleay, one of the "Leaf Insects" (Phasmidce), 

 with newly laid eggs, and larval forms in various stages of growth 

 one of them just hatched from the egg. The insects are not 

 uncommon in certain parts of Northern New South Wales on 

 the native scrub; but the specimens exhibited were forwarded 

 from the Brunswick River, with the information that they were 

 attacking the foliage of fruit trees, particularly that of the Plum, 

 a change of food-plant not previously recorded. As the insects 

 reposed on a pot-plant, attention was called to the protective 

 mimicry afforded, more especially, by the flat leaf -like expansions 

 along: the sides of the abdomen and the lesfs. 



Mr. Fred. Turner exhibited a very fine series of Austra- 

 lian grasses, collected on Glenariff Station, via Byrock, a little 

 east of the Darling River, comprising the following twenty-eight 

 species: — Atnj^hihromus neesii, Steud.; Amphipogo7i strictus, R.Bi'.; 

 Andropogon hombycimis, R.Br.; A. sericeus, R.Br.; Anthistiria 

 avenacea, P.v.M.; A. ciliata, Linn.; Aristida behriaita, F.v.M.; 

 A. stipoides, R.Br.; Chloris trnncata, R.Br.; Cynodon dactylon^ 

 Pers. ; Danthonia bipartita, F.v.M.; Diplachue Jusca, Beauv. ; 

 Eleushie f(igyptiaca,^evi.', Eragrostis eriopoda,l^enth.; E.lanijlora, 

 Benth.; E. pilosa, Beauv.; Eriachne obtusa, R.Br.; JVeurachne
