NOTES AND EXHIBITS. 
Dr. Cox stated that he wished to place on record the regularity 
with which the large green Cicada makes its appearance each year in 
the neighbourhood of Sydney. For the last 17 years he had noted 
the dates, which he found to range from October 14th to 30th. 
Mr. Fletcher read a letter from Hon. Dr. Creed, M.L.C., to the 
President, calling the attention of the Society to the sudden 
appearance of myriads of mice in various country districts of this 
colony, and suggesting that the subject was one worthy of investi- 
gation, as, owing to the destruction of crops and food for stock, 
the matter was becoming one of economic importance. Mr. 
Fletcher pointed out that the subject was one which had not been 
entirely overlooked, since in the Society’s Proceedings for 1887, 
p. 447, would be found a paper by Mr. K. H. Bennett, giving 
particulars of an invasion of rats in the western portion of N. S. 
Wales during February, 1887. 
Mr. Fletcher exhibited some young specimens of Peripatus 
Leucharti, Sang., the progeny of one of the three living specimens 
exhibited at the Society’s meeting in June last. The mother, for 
a period of four months, lived in a tin with damp moss and 
decayed leaves, but died a few days ago after giving birth to four 
young ones. These, when discovered (they were then a few days 
old) last Wednesday, were about 7 mm. long when extended, and 
nearly colourless, though with a lens the dark median nodose 
dorsal line, and the dark broad lateral band on each side were 
distinctly sketched out, the antennae also dark ; during the last 
few days the pattern and colour (dull slaty-blue or grey) have 
become still more pronounced, and a little diffused ferruginous red 
has made its appearance. 
Also a number of botanical specimens, recent acquisitions to 
the herbarium collected at various excursions, all from the county 
of Cumberland or contiguous counties, including Zieria involu- 
crata, B.Br. ; Z. granulata, C.M. ; Bossicm Stephensoni, F.v.M. ; 
Pultenoia hrunioides, Meiss. ; P. polifolia, A. Gunn. ; Acacia 
pruinosa^ A. Cunn. ; A. glaucescens, Willd. ; Samolus V alerandi, 
Linn. ; Persoonia oblongata, A. Cunn.; Grevillea trinervis, R.Br.; 
G. sericea, B. Br., var.
