2. The Australian Hydvomeduse, by R. von Lendenfeld, Ph.D., 
Part I. It is proposed in this paper to describe a series of new 
species of Hydvomeduse of our shores. As most essays on the Hy- 
dvomeduse dwell exclusively either on the Hydvoid Zoophytes or on the 
Meduse, and as this course is not in accordance with our present 
view of zoological classification, a new classification of the Hydro- 
meduse is proposed. The classification is marked out in the pre- 
sent paper. The present paper forms a Pvodvomus of a system of 
the Hydroid Zoophytes and Craspedote Meduse, which will be used and 
marked out in detail in subsequent papers, 
The order of the Hydvomeduse is here divided into five Sub- 
orders and twenty-one tamilies. 
3. “The Scyphomeduse of the Southern Sea,” by R. von Len- 
denfeld, Ph.D., Part II. This paper is a continuation of the paper 
read at the last meeting of the Society, and contains a description. 
of all the species of the third order of the Scyphomedusa, the Cubome- 
duse, which have been described from the South Sea. 
4. “On some Fossil Plants from Dubbo, N. 8. Wales,” by the 
Rey. J. Milne Curran, F.G.S. This paper, which was illustrated 
by specimens in an extraordinary state of preservation, and 
mounted for the microscope, is a very careful essay towards the 
determination of the (so-called) Hawkesbury beds at Dubbo, and 
names or describes as belonging to that formation the following 
forms, viz.:—Sphenopteris crebva, S. glossophylla, Neuropteris australis, 
Thinfeldia odontopteroides, T. media, Alethopteris Curvam, A. concinna, 
Merianopteris major; and a Conifer, Walchia milneana. Of new 
species Mr. Curran names Odontopteris macrophylla (Alethopteris), (Pe- 
copteris) australis, Hymenophyllipes dubia, Podozamites sp., and one 
conifer set down doubtfully as Walchia piniformis. 
The President remarked that this paper was an important con- 
tribution to the Geology of N. S. Wales. Several of the fossils 
described from the Dubbo formation were indistinguishable from 
some which he had collected from the shale beds interstratified 
with the Hawkesbury Sandstone at Sydney and near Mount Vic- 
toria; they also exhibited the same remarkable state of preserva- 
tion. He had no.doubt the Dubbo beds, from which Mr. Curran 
had obtained his specimens, belonged to the Hawkesbury forma- 
tion. 
Mr. Ramsay exhibited a fine collection of Marine animals in 
illustration of the new and perfect methods of mounting and pre- 
serving specimens in use by Senor Lo Bianco, at Dr. Dohrn’s Zoo- 
logical Station, Naples. Among the exhibits were Tvachypterus 
tenia, Torpedo ocellata, Pennana Carolinu, Endendrium vamosum, Zoobo- 
bryan pellucidum, Pennatula phosphora, A utidon rosacea, Chromodoris elegans, 
Pleuvophyllidea lineata, Pyvosoma elegans, Cestus veneris, Rhysostoma 
pulmo, and many other beautiful preparations. 
The President exhibited a portion of the lower jaw of a Dipro- 
todon 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 “4 
Range, as well as on the low-lying plains of the Darling District,
