MONTHLY MEETING. 
C. 8S. Wilkinson, F.G.S., &c., President, in the chair. 
New member—Capt. G. R. Stevens, F.R.G.S., F.R.A.S. 
Papers—1. ‘‘ Supplement to the Descriptive Catalogue of the 
Fishes of Australia,” by William Macleay, F.L.S., &c. This paper 
contains references to, or descriptions of, 157 species of Fishes not 
mentioned as Australian in the previously printed catalogue. The 
species here described tor the first time are from the pens ot Dr. 
Klunzinger, Dr. Gunther, Messrs. De Vis, Ramsay, Macleay, and 
R. M. Johnston. The total number of Australian Fishes now 
amounts to 1251 species. 
2. ‘On some new Batrachians from Queensland,” by Charles W. 
De Vis, M.A. This paper contains descriptions of three new 
species of Frogs, collected at Mackay, by Mr. H. Ling Roth, and 
named by the author as follows :—Lumnodynastes lineatus, approach- 
ing L. Peronw, but distinguished by shorter hind limbs, and con- 
tinuity of dorsal stripes; L. olivaceus ; and Hyla Rothat, 
3. ‘On Plants indigenous in the immediate neighbourhood of 
Sydney,” by Mr. Haviland. This, the sixth of the series, gives an 
account of some species of the genus Darwima, showing the sup- 
posed manner of fertilisation, and explaining, to some extent, the 
prevalence of the species D. fascicularis, notwithstanding the great 
disproportion between the fertilised and the fertilising flowers. 
4. ‘Studies on the Elasmobranch Skeleton,” by William A. 
Haswell, M.A., B.Sc. The species chiefly described are—Curcharo- 
don Rondeleti, Cvrossorhinus barbatus, Heptanchus indicus, Pristiophorus 
civvatus, Trygonorhina fasciata, Trygon pastinaca, and Hypnos submger. 
The separation of Cvossorhinus from the Scyllide is regarded as 
fully justified. The existence of a mesial ventral cartilage in rela- 
tion to the pectoral arch of Heptanchus is pointed out, and some 
hitherto unnoticed modifications in the arrangement of the 
branchial arches in Tvygonorhina, Tvygon, and Hypnos are described. 
Mr. Macleay exhibited for Mr. James Macdonald, who was 
unable to be present, a specimen of a very curious little fish, which 
his nephew, Master John D. Wilson, had captured at the North 
Shore in an empty shell. Mr. Macleay said that it was a species 
of Salanas, and as far as he had been able to examine it, thought 
it was new. 
Mr. Pedley exhibited three specimens ot Centriscus gvacilis, an 
extremely rare fish in Port Jackson. 3

Papers—(1.) ‘‘ Monograph of the Australian Sponges,” by R. 
! von Lendenfeld, Ph. D. Part 1. 
This paper is introductory to a monograph upon the Australian 
sponges, large materials for which have already been accumulated 
by the author, partly from his own collections, and partly from 
those in the Museums of Christchurch and Dunedin, New Zealand, 
and of Adelaide, South Australia. The real investigation of this 
branch of the Ccelenterata may be said to begin with the work ot 
Grant, 1826; to have risen to a new and much higher level under 
Schulze, 1875-1881, and to have been continued by Lollas, Keller,
