NOTES AND EXHIBITS. 505 



Notes and Exhibits. 



Dr. Ramsay exhibited the seed vessel of Adansonia digitata 

 (Sterculiacese), the Baobab of Africa, about 16 inches in length, 

 and of an elongate oval form, and he stated that he had been 

 successful in growing some plants from the seeds. 



Mr. Palmer exhibited a specimen of Mylitta sp., from Burwood, 

 known as Native Bread, but so hard as to be quite uneatable. 

 Also, the seed vessels of Martynia proboscidea. 



Mr. Haswell exhibited a living individual of the species Asta- 

 copsis serratus, the red variety from Mt. Wilson, which when 

 alarmed or angry emits a distinct " fuffing " sound produced by 

 friction of the joints of the abdomen on one another. Also, a 

 Cicada, showing the muscular apparatus and other arrangements 

 by which the "song," commonly but erroneously referred to the 

 vibrating " tympana," is produced. 



Mr. Trebeck exhibited a fragment of auriferous iron ore from 

 Mount Morgan. In this rock no gold is visible to the eye, but is 

 nevertheless present in the average proportion of 9 oz. to the ton. 



Mr. Wilkinson exhibited a series of bones, scutes, &c, of 

 Megalania, a gigantic Lizard from Lord Howe Island, fossilized in 

 a coral rock of loose structure. Dr. Batusay showed that the 

 species must be regarded as quite distinct from M. prisca, Owen, 

 found on the Upper Condamine. 



Mr. Wilkinson also exhibited the right ramus of the lower jaw 

 of Thylacoleo carnifex, in absolutely perfect condition, and pro- 

 bably, in other respects also, the finest specimen ever discovered. 



Mr. Macleay exhibited a specimen of Caranx ciliaris, a, rather 

 rare fish from Port Jackson, presented to him by J. B. Hill, Esq. 



Mr. Smithers exhibited fine specimens of native copper from the 

 Keelbottom Copper mine, near Townsville.
