the CHELIFERA and Scorpions abound; the Spiders are ex- 
tremely numerous, and of many families, and the AcaRIDZz, 
Ixopip#, TromBip#, GAMASID&, &c. abound throughout the 
country. The Class MYRIOPODA comprises in Australia 
numbers of JuLIDm, and an amazing number of species of 
ScoLOPENDID&. 
The CRUSTACEA, the last Class of the Anthropoda, 
are, as far as the Malacostracea are concerned, well known. 
Mr. Haswell, M.A.,B.Sc., having lately completed an excellent 
catalogue of them. The number of species by that catalogue 
is 5388, which, with others described since, will probably bring 
the total to 600. Mr. Haswell has also lately published a 
paper on the Pycnoconipz of Australia, about eight in 
number. 
The other Sub-classes of the Crustacea, the EnTomos- 
TRACA, Eprzoa, and CiRREPEPIA, are undoubtedly numerous, 
but they have been very little studied. 
The VERMES, the fourth Sub-kingdom of Animals, are 
in all their heterogeneous Classes well represented in Australia, 
but with the exception of some groups of the ANNELID# and 
Potyzoa, are very little known. Mr. Haswell has lately 
described a number of the Australian forms of the Order 
CumtTorpopa. The OLricocumTa are few in number, but 
comprise one at least giant species. H1IRUDINID# are numerous. 
The ScoLEcipA are probably as numerous in Australia as in 
any part of the world, but no one has paid much attention to 
them. All the Mammals, Birds, and Fishes seem to be well 
stocked with them, all probably distinct species; but the genera 
seem to be the same as in other places. All, or nearly all, the 
Entozoa of man and the domestic animals are found in 
Australia, but they probably came with the European. 
The ROTIFERA are believed to abound. Sagitta is 
found. : 
The Fifth Sub-kingdom of Animalia, the EC HIN O- 
DERMATA, are exclusively Marine Animals, and in a 
country with an extensive seaboard and a favourable climate 
like Australia, might be expected to hold a predominating 
position, and they do so. 
The vast mass of coral reefs and islands known as the 
Barrier Reef, extending from the latitude of about 25° 
to 8° south, or until it reaches New Guinea, skirting the 
East Coast of Australia for over 1000 miles at a distance 
varying from three to ten miles from the coast, enclosing 
a smooth and warm sea, and receiving through numerous 
passages the clear waters of the ocean without, offers for all 
Marine Animals a haven of the most tempting character, and
