nated in the oviparous species. — Professor Stephens exhibited a photo- 
graph and a sketch forwarded by Mr. C. Jenkins, representing a fossil 
from the Devonian formation of the Murrumbidgee Val!ey, near Yass. This 
very remarkable specimen is the head of some Ganoid fish, evidently belon- 
ging to the Devonian period, and characterised by strong bony scales, deeply 
sculptured, and united by close textures. Two of these are perforated by 
large sub-circular orbits for the eyes. Other portions of the same specimen 
had been forwarded, to the Australian Museum while Mr. Jenkins was en- 
gaged in the exploration of the Covan Caves; and some other fragments 
have since, it is believed, been recovered. Mr. Jenkins is inclined to refer 
it to Asterolepis (which is closely connected with Pterichthys), but chiefly on 
account of the character of sculpture of the scales. On the same ground, he 
doubts its relationship to Cacosteus or Cephalaspis. Prof. Stephens added, 
that without the actual specimen before them with all its collected fragments, 
it would be premature to determine even the genus of this ancient fish, but 
pointed out that it appeared to have some points of resemblance to Macro— 
petalichthys of the North American Devonians. — Mr. Macleay exhibited 
specimens of a small Moth (Tineidae), the larva of which was at present 
creating great havoc in the vegetable gardens in and about Sydney, comple- 
tely eating up the leaves of the cabbages and cauliflowers, and rendering the 
entire crop utterly useless. ‘The Caterpillar, a number of which were ex- 
hibited, is an active, slightly hairy, green worm, the pupa is also green and 
is fastened on the under side of the leaf on which it has fed, by a cocoon, of 
beautiful open lace work. The rapidity with which this insect seems to re- 
produce itself is most astounding, and accounts for the short work it makes. 
of a bed of cabbages. The insect was, it is said, first noticed last year, and 
then not in destructive numbers, so that it will probably be found to be an 
importation. — Mr. Macleay also exhibited the foetus of Halmaturus rufi- 
collis, taken from the pouch of the mother, with the umbilical cord attached, 
illustrating the extremely early age at which the young leave the uterus. — 
Mr. H. A. Gilliat exhibited a collection of cretaceous fossils from the 
Mount Brown diggings. With reference to this exhibit the Vice-President 
made a few remarks on its value and interest. He said that the cretaceous 
formation was known to extend throughout the whole eastern interior of the 
Continent, and probably through the centre, but not much was known of 
the fossils. The abundance of Avicula alata, Eth., in this collection showed 
such a wide-spread prevalence of this fossil, that he considered it the most 
characteristic species of the formation. ‘The rock was curiously like the 
Greensand of Europe. The collection contained valuable additions to our 
knowledge of the fauna. — Mr. J. J. Fletcher exhibited (1.) A specimen 
of a Giant Earthworm, 25 in. long, from Burrawang, N.S.W. It probably 
belongs to Prof. M’Coy’s genus Megascolides, and its existence in this colony 
is now recorded for the first time. (2.) The plates Dendrolagus inustus and 
D. ursinus from Profs. Schlegel and Müllers work on the Mammals of the 
Indian Archipelago, for comparison with the specimen of a new species of 
Dendrolagus exhibited by the Hon. Wm. Macleay at the last meeting, (3.) 
Specimens of the Lizard referred to in his paper. — Professor Stevens ex- 
hibited a Chrysalis of a Dana's, secured by a silk line to a leaf of an exotic 
Pelargonium.
