1. Zoological Society of London. 
16th May, 1893. — Extracts were read from a letter addressed to Prof. 
Newton, F.R.S., by Prof. E. C. Stirling, of Adelaide, respecting the recent 
discovery of a large series of remains of Diprotodon, Phascolomys, and other 
Mammals at Lake Mulligan, in South Australia, about 600 miles north of 
Adelaide. It was anticipated that when these remains were received and 
examined very important additions to our knowledge of the extinet Mammal- 
fauna of Australia would follow. — Mr. Beddard, F.R.S., read a paper 
upon the structures termed »atrium« and »prostate« in the Oligochaetous 
worms, in which reasons were given for believing that all these structures 
were reducible to one common plan. — Mr. G. B. Sowerby, F.Z.S., read 
the descriptions of fifteen new species of shells of the family Pleurotomidae 
from different localities. — A communication was read from Mr. A. H. 
Everett, C.M.Z.S., containing a revised list of the Mammals inhabiting 
the Bornean group of Islands, that is, Borneo, and Palawan, which, as Mr. 
Everett had shown in a previous paper, belongs zoologically to Borneo. — 
Mr. O. Thomas, F.Z.S., read a paper containing an account of a second 
collection of Mammals sent by Mr. H. H. Johnston, C.B., F.Z.S., from 
Nyasaland. The present series (collected, like the former by Mr. Alexander 
Whyte, F.Z.S.) consisted of about 75 specimens, referable to 30 species, of 
which a large proportion were additional to the Fauna of Nyasaland. — Dr. 
P. Sonsino, of Pisa, read some notes on specimens of parasitic worms of 
the genus Distomum, of which he had lately examined specimens. — P. L. 
Sclater, Secretary.
