Papers. — "Two New South Australian Nephilae," by H. R. 

 Hogg, M.A., F.Z.S., communicated by Prof. Stirling, M.D., 

 F.R.S. ; "Brachipods of South Australia," by J. C. Verco, 

 M.D., F.R.C.S., with exhibits of specimens and diagrams.

 each species in its growth repeating its genealogical history, so 

 that the same species in different stages of development may 

 be referred to different species or genera."
