3) New species of Land and Freshwater Mollusca from Maclay-Coast and 

 Triton Bay, New Guinea. By John Brazier, C.M.Z.S., etc. Five species 

 are described as new under the names of Helix [GeotrocJms] Gorenduensis and 

 Maclayana , Helix [Rhysota] Achilles , Melania Wallariensis and Paludina 

 Kowiayiensis. The names are given of some other shells found on the Maclay- 

 Coast. — 4) Addendum to the Monograph of the Australian Sponges. By 

 R. von Lendenfeld, Ph.D. Two new species of Halme are described as 

 representing five varieties, which, however, appear to run into one another 

 so closely that these species may not in reality be distinct. — 5) Description 

 of a new species of Com. By E. P. Ramsay, F.R.S.E., and J. Douglas- 

 Ogilby. The name of Coris rex is given to this fish. It was taken near 

 Bondi Heads a few days ago and presented to the Australian Museum by 

 Mr. G. Billington. — Mr. Prince exhibited a large number of Volutes, 

 difi'ering very considerably in general appearance, but all belonging to V. 

 piperita, though including the supposed species V. Ruckeri, V. Macgillivrayi, 

 V. Cathcarti, and V. Rutilla. — Dr. Cox exhibited specimens sent from the 

 Hunter by Mr. J. S. Skeat, including teeth and bones of horses from deep 

 alluvium ; and from the upper carboniferous near Maitland, representatives 

 of the following genera : — Spirifer , Pleurotomaria , Productus , Aviculo- 

 pecten, Bellerophon, Sanguinolites . The beds from which these fossils were 

 obtained overlie the West Maitland Coal Seams. Also excellent casts of 

 fishes taken in gelatine, and coloured after life. Also a very splendid 

 example of the flower and fruit of Eucalyptus ßcifolia, of West Australia. — 

 Mr. Masters exhibited some Moths, apparently Pyralidae, bred from Cater- 

 pillars found feeding on a Coccus which infested the common Zamia. The 

 Caterpillars in the course of a few days, completely cleared the plant of the 

 scale, devouring the Coccus and forming with the scales or empty skins, a. 

 complete covering for themselves, which they carried about on their backs. 

 They fed at night, and during the day fixed themselves securely to the mid- 

 rib of the frond. — Mr. Whitelegge exhibited living specimens of Cor- 

 dylophora, a fresh water Hydroid Zoophyte, from Parramatta. Also, some 

 very beautifully mounted specimens of the same under the microscope. 

 Dr. Lendenfeld expressed his belief that this exhibit was probably a new 

 form. — Mr. Macleay exhibited a remarkably fine specimen of Eunice sp.? 

 taken in Sydney Harbour by James Hill, of Vaucluse.
