Abstract of Proceedings, November 28th, 1906. — Mr. D. G. Stead 

 stated that during the month a magnificent adult example of the "Government 

 Bream", Genijoroge scbac (Cuv. & Val.j had been forwarded to Sidney from 

 Cofi''s Harbour, thus making a second record of the occurrence of this hand- 

 some northern species in New South Wales waters. Mr. Stead also exhi-^ 

 bited a specimen of the rare Syngnathid Pipefish, Syngnathus altirosti'is Ogilhy, 

 captured in the estuary of the Bellinger River by Mr. R. S tace; and a young 

 example (the short-beaked form), measuring 170 mm, of the Skipper Garfish, 

 Scomhrcsox forsteri Cuv. & Val.; at the same time stating that, about the 

 middle of the month, these Scombresocids were present in the waters of Port 

 Jackson in immense numbers. — Mr. G. A. Waterhouse exhibited a pupa 

 and perfect insects of Troides j^namus }Joseidon. The pupae were found at 

 Cape York and sent to Sydney, being received during the first week in Sep- 

 tember. The first imago (Q) emerged on the 31st October, the second [Q,] 

 on 1st November, and the third [çf] on 6th November. Two pupae were 

 still alive. — Mr. H. S. Mort showed specimens of a freshwater mollusc, 

 Vivipara stelomphora Bgt. var. maUeata Rve., from Ibusuki, Satsuma, Japan. 

 This species inhabits the warm water near the hot springs, and is called 

 "Tabina" by the Japanese. — Mr. H. I. Jensen showed specimens of lava 

 from Samoa and Tonga; shells [Ostrea crista-galli, Spondylus sp., and Tridacna 

 elongata) from a raised beach at Lautoka, Fiji; and a series of lantern slides 

 showing various aspects of the intermittently active volcano in Savaii, the 

 character and extent of the lava-flows and the generation of clouds of steam on 

 their reaching the sea, the destruction of vegetation caused by the floAvs, and 

 the extension of the land-surface due to the steady pouring of lava into the 

 sea. — Professor Klaatsch, of Heidelberg, a visitor, on the invitation of 

 the President, exhibited a series of lantern views illustrating his recent 

 travels among the Aborigines of the North coast of Australia between Broome, 

 on the North-west, and the Gulf of Carpentaria, and at Melville Island, for 

 the purpose of ethnological and anthropological study. The Aborigines of the 

 northern half of the Continent were more numerous than was generally sup- 

 posed^ and their number might be estimated as between 100000 and 150000. 

 Professor Klaatsch concluded his very interesting observations with a fervent 

 appeal, on behalf of te Northern Blacks, for greater consideration in the way 

 of a more adequate provision of reserves and for more eff'ective protection 

 than the Southern Blacks had received in the past. Apart altogether from 

 humanitarian questions, the demand for their more enlightened treatment was 

 justifiable on scientific grounds alone. — Professor Wilson gave expression 

 to the pleasure and interest which Dr. Klaatsch's narrative and conclusions 

 evoked; and he expressed his cordial concurrence with the timely note of 

 warning which had been given, and emphasised its importance. — 2) New 

 Australian Species of the Family Aeschnidae [Neuroptera: Odonata]. By 

 R. J. Tilly ard, B. A. — The species herein added to the Australian list form 

 about as miscellaneous and remarkable a set of insects as it would be possible 

 to find, and serve to show the composite character of the Australian Odonate 

 fauna. They comprise an East Indian species, a Chilian species [Petalia Apollo 

 Selys [Q], of the subfamily Cordulegasterinae , determined by Dr. Ris, of 

 Belgium), and three species described as new, of which one is referable to an
