MEETINGS OF SOCIETIES. 329 
mentioned by Mr. Curran had not been observed by any of those 
present. 
Mr. Masters exhibited a specimen of Ibacus antarcticus which 
had been taken lately at Newcastle, and presented by Dr. Cox to 
the Macleay Museum. He stated that it was, he believed, the 
largest specimen of that very rare crustacean that had been found 
in Australian seas. 
Mr. Trebeck exhibited two samples of wool grown on the same 
sheep. The first, grown in Victoria in 1879, was fully four inches 
long, and showed every good quality of the highest type of comb- 
ing wool. The second, grown this year on the east side of the 
Liverpool Range, was scarcely 14 inches long, and approached in 
character the early Mudgee wools of Silesian type. In the first 
specimen, the normal black tip of the old Merino had disappeared 
under the influence of Victorian cultivation; but after a period of 
growth in New South Wales, the wool of the sam ram reverted to 
the original type of the pure Merino. The contrast between the 
two samples was due simply to the effects produced by the differ- 
ences in the climate, soil, and culture. 
Dr. von Lendenfeld exhibited a specimen of Haliphysema 
suberites nov. spec., obtained from Macrocystis in Port Jackson. 
This Haliphysema is in appearance somewhat similar to H. vamu- 
losa. The skeleton of the hollow stem consists of truncate longi- 
tudinally disposed spicules. Similar spicules with bulbous cen- 
tripetal ends are found in the spherical body; these are situated 
radially. In the stem sand-particles are found, and protrude two- 
thirds of their lengths. Dr. Lendenfeld was inclined to consider 
the spicules to be produced, and not collected by the Haliphysema.

by Chas, W. de Vis, M.A. Over 30 new species are described in 
this paper, belonging to the families Athevinide, Mugilide, Pomacen-

2. ** Observations on the Temperature of the Sea on the East 
Coast of Australia,” by N. de Miklouho-Maclay. The paper gives 
in a tabular form the result of the Baron’s own observations on 
various parts of the coast in the month of July of the years 1878 
and 1883 
. On two new species of Macropus trom New Guinea,” by N. 
de Miklouho-Maclay. These species, named respectively Macropus 
jukestt and Macropus gracilis, are from the neighbourhood of the 
Mount Owen Stanley Range. 
4. “A Monograph of the Australian Sponges, Part III.,’ by 
R. von Lendenfeld, Ph.D. In this paper the Calcareous Sponges 
belonging to Polejaeff’s Group Homoccela are described. A new 
Species, a representative of a new family, which connects the 
Homoccela with the Heteroccelia is described in detail by the 
author. From the tact that the entoderm cells are all alike, and 
that nevertheless a complication occursas in the Sycanidea, in the
