Leptothrix, exhibited by Mr. Pedley, should have been reported as 
a fungoid growth, and not a bacterium, found in decayed teeth.

Papers— (1) “‘ Notes on a collection of Fishes from the Bur- 
dekin and Mary Rivers, Queensland,” by William Macleay, F.L.S., 
&c. Fifty-two species of fishes are here recorded as having been 
taken by Mr. Morton, of the Australian Museum, within the 
mouths of the above-named rivers. Of these, Mr. Macleay classes 
18 as sea fishes; 11 as salt water fishes occasionally entering 
rivers ; 7 as fresh water fishes occasionally visiting the sea; and 15 
entirely fresh water fishes. The new species described are Ser- 
vanus estuavius, Thevapon fuliginosus and parviceps, Diagramma labiosum, 
Corvina argentea, Cavanx compressus, Cybium semifasciatum, Platycephalus 
movtont, Eleotris planiceps, Atherinichthys maculatus, Mugil vamsayi, 
Chatoéssus elongatus, Anguilla marginipinnis, and Teniura mortoni. 
(2.) ‘‘ Notes on a vivaparous Lizard,” by J. J. Fletcher, M.A.. 
B.Sc. The author’s attention had been drawn to the subject during 
last January, when he obtained at Burrawang several examples of 
female lizards in an advanced state of pregnancy. The embryos 
were from 2 to 3 inches long, enveloped in a thin and transparent 
chorion, quite devoid of the calcareous matter with which it is more 
or less impregnated in the oviparous species. 
(3.) “ Notes on a method of obtaining water from Eucalyptus 
roots, as practised by the natives of the country between the 
Lachlan and Darling Rivers,” by K. H. Bennett, Esq. The 
author describes the method by which, during times of drought, 
when cut off from the rivers by fear of the hostile tribes on the 
banks, the back-country natives used to extract their entire supply 
of water from the roots of certain trees—3 species ot Hucalyptus, 
a species of Hakea, anda Kurrajong. The roots are dug out, cut 
iuto lengths, and the pieces set on end in a water-bag until the 
water drains out. The water is described as perfectly clear and 
free fro. any unpleasant taste or smell. 
Professor Stephens exhibited a photograph and a sketch for- 
warded by Mr. C. Jenkins, representing a fossil from the Devonian 
formation of the Murrumbidgee Valley, near Yass. This very re- 
markable specimen is the head of some Ganoid fish, evidently 
belonging to ;the Devonian period, and characterised by strong 
bony scales, deeply sculptured, and united by closetextures. Two 
of these are perforated by iarge sub-circular orbits for the eyes. 
Other portions of the same specimen had been forwarded to the 
Australian Museum while Mr. Jenkins was engaged in the explora- 
tion of the Covan Caves; and some other fragments have since, 
it is believed, been recovered. Mr. Jenkins is inclined to refer it to 
Astevolepis (which is closely connected with Prerichthys), but chiefly 
on account of the character of sculpture of the scales. On the 
same ground, he doubts its relationship to Cacostews or Cephalaspis. 
Prof. Stephens added that without the actual specimen before 
them with all its collected fragments, it would be premature to
