NOTES AND EXHIBITS. 



Mr. Carter exhibited his collection of representatives of the 

 genus Adelium, comprising a majority of the known species, in 

 illustration of his paper. 



Mr. Kesteven exhibited a dissected specimen of Hyla aurea 

 which contained in its stomach a somewhat smaller specimen of 

 apparently the same species. 



Mr. A. A. Hamilton exhibited a two-flowered specimen of the 

 rare orchid Adenochilus Nortoni from Lawson on the Blue Moun- 

 tains, whereas the type-specimens described by Fitzgerald had 

 the flowers solitary; specimens of Persoonia angulata R.Br., from 

 Wentworth Falls, Leura and Katoomba, an extension of the 

 range of a somewhat rare plant; and an example of the Waratah 

 (Telopea speciosissima R.Br.) from Waterfall, with pinnatisect 

 foliage of an uncommon character 



Dr. Greig-Smith showed a Schizosaccharomyces, isolated from 

 molasses; and he pointed out the relations which the genus has 

 with the Saccharomycetes and with the Bacteria. 



Mr. A. Basset Hull exhibited a series of eggs of the 

 Silver Gull (Larus novce-hollandice Stephens) from the gull 

 rookery at Montague Island, displaying two striking muta-

 were (A.) uniform pale blue, without any trace of markings: 

 (B.l) glossy white, faintly blotched with pale red and purplish- 

 red suffused markings and a few dull red spots, distributed over 

 the whole shell; (B.2) creamy-white, blotched with purplish-red
