398 THE PROCEEDINGS OF THE LINNEAN SOCIETY 



The Reptiles offer considerable practical difficulties in the way 

 of demonstration ; so that lessons should perhaps be confined to 

 the Fresh-water Tortoise, the Black Snake, Carpet or Diamond 

 Snake, and the so-called Iguana or Gohanner. 



The metamorphosis of the Batrachians can be illustrated by- 

 examples of any species. 



As almost all our larger Fishes are popularly known by 

 most erroneous names, and the same fish may have as many 

 aliases as it has habitats, while the same name is applied to 

 different fish in different waters, there is urgent need for an 

 attempt, at least, to overcome this enormous confusion. In the 

 meantime we may select two well-known species for illustration 

 — the Snapper for the coast districts, and the Murray Cod for the 

 interior. Examples may also be obtained to illustrate the Mul- 

 lets, Eels, Scombers, Herrings, Sharks, and Rays. But the 

 careful study of some few forms must suffice for the present. In 

 the Annulose sub-kingdom, the Crustaceans would be illustrated 

 by the (so called) Lobster of the coast, and the Miami of the 

 interior. But any good-sized Crab might be used in the object 

 lesson. The Barnacles, Entomostraca, &c, would have to be 

 passed over, as creatures whose true structure and relationship 

 are outside the sphere of common observation. 



The Insecta furnish an abundant store of specimens in all 

 parts of Australia, and of all families. They are readily preserved, 

 and are, in all respects, except that of size, especially suitable for 

 our purpose. Among the Coleoptera, I should propose as objects 

 any large examples of the Carabidse, Lamellicorns, Buprestids, 

 and Curculios. Distinctions of family alone should be observed, 

 but the general coleopterous conformation precisely and carefully 

 studied, so far as is possible without adventitious aid. The 

 common Bee, the Blowfly, any large Moth or Butterfly, any large 

 Cicada, the common Cockroach, any Grasshopper or Dragonfly 

 will afford the means of identification of their respective orders. 

 The Myriapoda and Spiders seem beyond the grasp of our method, 

 as also the Echinodermata and Hydrozoa. 



The Mollusca must only be represented by any available Cepha- 

 lopod, any Helix, any marine Gasteropod, and any Conchifer, the
