genera which are identical with some previously known, and cor- 
rects some doubtful synonyms. 
7. “Note on the Flight of Insects,” by R. von Lendenfeld, 
Ph.D. Dr. Lendenfeld contests the views of the French physio- 
logists that the position and movements of the wings of insects are 
merely the results of the mechanical influence of the resisting air, 
and gives instances where muscular contraction had been clearly 
roved. 
8. ‘* List of Recent Shells found in layers of clay on the Maclay 
Coast, New Guinea,” by John Brazier, C.M.Z.S., &c. The names 
of 38 species of recent shells are here given, all belonging to the 
surrounding seas, but collected at an elevation ot nearly a thousand 
feet. 
g. “A Revision of the Australian Lzemodipoda,” by William 
A. Haswell, M.A., B.Sc. Ten species are described as known, two 
of which inkabit Australian coasts, including three species of Proto, 
to. ‘“*A Revision of the Australian Isopoda,” by William A. 
Haswell, M.A., B.Sc. A revised list of all the known Australian 
species, with observations on the genus Stenetyviwm, and descriptions 
of new species of Anceus, Tanais, and Pavathuva, and of a remark- 
able new Spheromid, having the head ornamented with three pro- 
minent horn-like processes. 
E. P. Ramsay, F.L.S., exhibited a Throwing Stone, used in 
warfare by the natives of Futuna, New Hebrides, which had been 
presented to the Australian Museum by Capt. Geo. Braithwaite, 
of the Dayspring. The stone was a cylindrical weapon, about 
two feet and a-half long, and two inchesin diameter, and had been 
cut out of a solid block of coral. Mr. Ramsay pointed out that the 
natives of Futuna were compelled to resort to coral tor their 
weapons, as there was no suitable wood on that island. 
Mr. Trebeck exhibited two samples of wool grown from the 
same ram in Victoria and Mudgee. The longer sample, grown 
under high culture at Ercildoune, is nearly five inches long, and 
has every good quality for which the Victorian combing wool is 
celebrated ; the shorter sample is of the same time of growth on the 
natural pastures of Mudgee, and is only about 14 inches long. 
Irrespective of the marked difference in length, the quality ot that 
grown on the natural pastures of Mudgee appears to be very much 
inferior in many points. This is unaccountable, as the Mudgee 
district is wel] known to produce merino wools of the highest 
quality. 
Professor Stephens exhibited the magnificent donation which 
the Society had lately received from the Rev. Dr. Woolls, consist- 
ing of a very large collection of New Zealand Lichens, all well 
preserved, mounted, and accurately named by Dr. Knight, of Wel- 
lington, New Zealand. For this donation a most cordial vote of 
thanks was accorded by the meeting. 
Dr. von Lendenfeld exhibited the Ctenophora of Port Jackson, 
described by him as Bolina Chuni, in different stages of development, 
alive in an aquarium. A live specimen of Nets cordigera, measuring 
a foot in length, was also exhibited by him.
