MONTHLY MEETING. 
Professor W. F. Stephens, M.4., F.G.S., President, in the chair. 
New members.—Messrs. E. G. W. Palmer, J. Mills, A. Hamilton, 
and J. Smithurst. 
Papers.—(1) ‘‘ A monograph of the Australian Sponges. Part IV. 
The Myxospongie,” by R. von. Lendenfeld, Ph.D. In this paper the 
Australian species are described. (The author partly adopts the view of 
Sollas regarding the separation of the Halisarcide and Gummine.) The 
structure of Bajalus,a new genus of Halisarcide, is described. The 
subdermal cavities are remarkably developed. _Ameeboid wandering 
cells were found in a dense layer beneath the outer skin. Gland cells 
are described. Sexual products mature only in the innermost part. 
The gastral cavity serves as a marsupium. The anatomy of Chondrosia 
ramsayi, n.sp., Chondrilla papillata, n.sp., and C. corticata, n.sp., shows 
some points of interest. Peculiar subdermal cavities are described in 
the former. The two latter possess a special cortical skeleton. 
The classification used is the following :— 
Il. ORDO. MYXOSPONGLA. Haeckel. 
SPONGES WITHOUT SKELETON OR WITH POLYACTINELLID FLESH 
SPICULES. 
I. Susorpo Myxina. Von Lendenfeld. 
Myxospongiz, with structureless mesodermal ground-sub- 
stance. Exceptionally few and distant fibrills. Identical 
with Halisarcine, O. Schmidt. 
8. Famitia OscaRELLIDZ. Von Lendenfeld. 
Myxine, with spherical ciliated chambers, for Haliscarca 
lobularis, O. Schmidt, Oscarella Vosmer. No Australian 
species. 
9. Famitia Hauisarcip£. Von Lendenfeld. 
Myxinz with sac-shaped elongated ciliated chamber. New 
genus Bajalus. 1 species.
