254 NOTES AND EXHIBITS. 



Ten.- Woods, in having its leaves linear to lanceolate and curved 

 inwards at the apex. A few of the specimens show that the stems 

 were flexible, reminding one of some of the Lycopodiaceas. One 

 species can hardly be distinguished from one figured by Mr. 

 Twelvetrees, from the Upper Permian of Eastern Russia. (Qt. 

 J. Geol. Soc, Lond., Vol. 38, p. 498, pi. 21, fig. 4.) 



In conclusion I may remark that there are some forms which 

 we should expect, which are not as yet recorded from Dubbo, 

 notably Tmtiopteris. 



With the foi-egoing list, imperfect as it is, it would be an easy 

 matter to make some attempt to correlate the Dubbo and 

 Ballimore beds with other well-known formations ; this I propose 

 to attempt in another paper.

NOTES AND EXHIBITS. 



Mr. Ramsay exhibited a fine collection of Marine animals in 

 illustration of the new and excellent methods of mounting and 

 preserving specimens in use by Senor Lo Bianco, at Dr. Dohrn's 

 Zoological Station, Naples. Among the exhibits were Trachypterus 

 Uenia, Torpedo ocellata, Pennaria Carolinii, Eudendrium 

 ramosum, Zoobotryon pellucidum, Pennatula phosphora, Autidon 

 rosacea, Ghromodoris elegans, Pleurophyllidea lineata, Pyrosoma 

 elegans, Cestus Veneris, Rhizostoma pulmo, and many other 

 beautiful preparations. 



The President exhibited a portion of the lower jaw of a 

 Diprotodon which had been found near Armidale by Mr. W. M. 

 Harris. It was interesting to note the occurrence of the remains 

 of this gigantic extinct marsupial on the summit of the Great 

 Dividing Range as well as on the low-lying plains of the Darling 

 District.
