744 PROCEEDINGS OF SECTION J. 



16. Birds— 



16^. The public parks of the city; native or introduced; 

 162. The River Yarra. 



17. Birds of— 



171. Ocean — e.g., Diving Petrel, Wilson's Petrel, Albatross; 



17-. Bay— e.^., Silver Gull, Pacific Gull; 



173. River and Swamp — e.g.. Darter (Plotus), Duck, Reed 

 Warbler (Acrocephalus) ; 



17^. Mountain — e.g., Black Cockatoo (Pycnoptilus), Lyre 

 Bird ; 



175. Plains — Wattled and Southern Stone Plovers, Song Larks 

 (Ginclorhamphus) ; 



17^. Lightly timbered country — e.g.. Tree Swallow (Petro- 

 chelidon). Tree Runner (Sittella). 



B. In a second room there should be — 



B^. A general zoological series and the principal types of 

 minerals and fossils from all parts of the world. 



In the general collection of fossils, each specimen should be 

 mounted on a board of a standard size, and coloured pale^green, blue, 

 or pink, to indicate the Primary, Secondary, or Tertiary Divisions. 

 On the adjacent wall, a large chai-t should be placed, showing the 

 classification in detail, with the three divisions in corresponding 

 colours. 



B2. Collections to illustrate Evolution or the History of Races, 

 Geographical Distribution, and Migration. 



This subsection should illustrate (by means of specimens in wall 

 cases) the history of animals. 



Such examples as uiagpies, crows, magpie larks, hawks, g'ulls, 

 frogs, and bandicoots, with descriptive matter to each label, would 

 illustrate what is meant by— Species, Genus, Family, Order, Class, and 

 Sub-kingdom (Phylum). Variation of species could be shown in the 

 comparison of Tasmanian magpies with those of Victoria; specimens 

 with reference to the struggle for existence (herring and flesh fly) and 

 natural selection (parrot) should be near at hand. 



Examples to show the different ways of getting a living — e.g., 

 cockchafer — grub and beetle — with others showing structures for 

 offence and defence — e.g., plover (Spur-wing), scorpion; others, again, 

 to show instincts for defence — e.g., sepia, certain crabs; concealment 

 by colour— flatheads (PlatycephuJa) ; protection by warning colour 

 — katipo spider, lady-bird beetle (Lets) ; mimicry — bees and wasps, 

 mimicked by harmless insects ; and, in the case of birds, drongo shrike 

 and cuckoo. 



Similar parts of different animals, showing modification from a 

 common tj'pe-T-Sea squirt and frog, sea urchin and star-fish. 



Life history of individuals— Barnacle (Lepas), white-throated 

 thickhead (Pachycephala).
