496 NOTES AND EXHIBITS. 



and islands are modelled to scale and surrounded by water. The 

 currents are produced by jets of air issuing from numerous little 

 brass tubes, and the motion of the water is made visible by 

 means of lycopodium sprinkled on its surface. The model was 

 constructed from the designs of Prof. A. W. Clayden, of Exeter, 

 England, and was purchased from the makers — Messrs. G. 

 Philip & Son — by Mr. S. Hordern. A similar model was acquired 

 some years ago by the Japanese Government. 



Mr. D. G. Stead exhibited examples of the following species of 

 fishes, which, he stated, were new to the fauna of .New South 

 Wales : — Dasyatis sephen (Forskal), from Clarence River; 

 Dasyatis uarnak (Forskal), from Clarence River; Epinephelus 

 tauvina (Forskal), from Macleay River; Geuyoroge sebce (Cuvier 

 and Valenciennes), from Broken Bay; Emmeliclubhys nitidus 

 Richardson, from Port Jackson; Auxis thazard (Lacepede), from 

 Port Jackson; Gasterochisma melampus Richardson, from Shoal- 

 haven; Bramichthys woodwardi Waite, from Port Jackson; and 

 Sphceroides pleurostictus (Giinther), from Clarence River. In 

 addition, he recorded for the hrst time the occurrence of the 

 well-known Albacore, Gernw germo (Lacepede) on the coast; an 

 adult specimen 43^ inches in length was taken during 1903 at 

 Port Macquarie, and portions of it had been handed to him for 

 determination. Mr. Stead also pointed out that Dasyatis sephen 

 above recorded is probably the most dangerous of all our sting- 

 rays, as it has a most powerful, muscular tail, and is able to 

 to strike further in any given direction with its long and sharp, 

 barbed spine, than any other species. 



Mr. Proggatt exhibited the larvae, pupse, cocoons and living 

 specimens of Axionicus insignis Pasc, taken from the stem of a 

 damaged Kurragong tree at Junee, N.S. W. Though the beetle is 

 very common upon the bark of this tree, this is the first that the 

 life-history had been recorded. The eggs appear to be laid in a 

 damaged spot on the bark; and the larvae burrow and feed in the 

 undersurface of the bark and the upper surface of the wood 

 beneath. This causes a great exudation of gum, and it is pro-
