Lepidopterous insect of which this can be said. It swarms in 
many parts of Australia, especially at Adelaide. It has probably 
been imported with the cabbage, but will eat almost any Crucifere. 
Its numbers are, | think, principally kept down in the larval 
state by small birds. The moth, though small and inconspicuous, 
may be readily recognised by unpractised persons from its habit ot 
projecting its antenne forward when at rest, as the Trichoptera do.

Papers, (1.) ‘*‘ Descriptions of new genera and species of 
Fishes,” by Charles W. De Vis, B.A. 
Two genera are described, Dactylophova of the family Cirrhitide, 
and Leme of the Family Amblyopinn. The new species described 
are—Gzivella carbonaria, Givella neuvalis, Dactylophova semimaculata, 
Platycephalus semermis, Polynemus speculavis, Leme mordax, Sphyreena 
stvenua, TIvochocopus sanguinolentus, Labrichthys dux, Plagusia notata, 
Synaptura cinerea, and Crossorhinus oynatus, 
(2) “Plants indigenous in the immediate neighbourhood of 
Sydney,” Paper IV., by Mr. E. Haviland. This referred chiefly 
to the reproductive organs of the genus Leptospeymum, and its mode 
of fertilisation. The author regards cross-fertilization as being 
probably the rule of this genus, this being brought about by two 
means :—First by the difference in the times of maturing of the 
anthers and stigma, and secondly by changes in their relative 
positions. 
(3.) ‘‘ Localities of some species of Polynesian recent Mollusca.” 
by John Brazier, C.M.Z.S.,&c. This paper gives with some de- 
tail all the synonyms of Pzvenopsis costata, of Quoy and Gaimard, 
and of Melania acanthica, Sea. Also the various localities in which 
they have been found. , 
Baron Maclay exhibited some beautifully preserved specimens 
of very delicate forms of marine life, such as Oceanza pileata, Salpa 
democratica, Alcyonium palmatum, &c., & These were prepared at 
the Naples Biological Sfation, under the direction of Dr Dohrn 
and may be obtained there at a reasonable cost, for study or ilus- 
tration. Even large specimens of Rhizostoma are perfectly and 
permanently preserved by this process. Baron Maclay also gave 
an account of various large animal preparations which had been 
preserved in the Berlin Museum by the Wickersheimer fluid, 
pointing out that the failures which had attended its use here, 
were due to too protracted immersion in the fluid. The objects 
when once well penetrated by the solution, should be withdrawn 
and kept in a dry state. 
Mr. Whitelegge exhibited a decayed leaf of some acquatic plant 
covered with a thick growth of Plumatella vepens. Also a specimen 
of fresh water sponge, undetermined, Both from a water hole in 
Moore Park.
