ABSTEACT OF PEOCEE DINGS 
OF THK 
Royal Society of South Australia 
(Incorporated) 
FOR 1904-5. 
Ordinary Meeting, November 1, 1904. 
The President (J. C. Verco, M.D., F.R.C.S.) in the 
chair. 
Exhibits.— A. H. C. Zietz, F.L.S., C.M.Z.S., a large 
number of the preserved skins of the Australian honey-eaters. 
The President exhibited three volutes from the lobster pots, 
Victor Harbour, the markings beautifully preserved, named 
respectively Valuta exopfanda, T. jjapiUosa, V. fulgetrum. 
These shells had been taken into the pots by the later occu- 
piers — hermit crabs — in search of food. 
Papers. — "New Species of South Australian Marine 
Mollusca," by J. C. Verco, M.i)., F.R.C.S. Dr. Verco, m 
introducing his paper, called the attention of the meeting to 
some interesting features in some of the molluscs therein 
described, the Glycimeris sordidus, the snell of which shows 
periods of rest, which are not found in its very near ally, G. 
pectenoides. In this latter shell, in the older stages, growth 
ceases, and the mantle contracts. Modiola pcenetecta, almost 
covered with epidermis, whilst M . australis is much less so. 
In these species a very marked difference exists in the fila- 
ments of the epidermis. Trigonia hednalli, probably a variety 
of margaritacea, a genus now found only in Australian seas, 
but remarkable as found fossil from very early geological 
ages. Dr. Verco also drew attention to very marked differ- 
ences between Ovula, of which a very tine specimen was shown, 
and Cyprcea.
