PREFACE. 
Although the manuscript of this Guide to the Fossil 
Galleries was prepared some years ago, various circum- 
stances prevented its publication at an earlier date. 
Its preparation has been carried out by Mr. Frederick 
Chapman, who has occupied the position of Palaeontologist 
to the National Museum since 1902, and whose excellent 
work in advancing the knowledge of the Australian hossil 
Fauna is so well known. 
With few exceptions, all the figures have been especially 
prepared for this work by Mr. Chapman from photographs 
taken from the actual specimens shown in the cases. 
This Guide is so arranged that the Australian fossils 
shown in the Eastern Gallery nearest the Russell-street 
entrance may be examined first. The exhibits in the Floor 
Cases and then those in the Wall Cases are described and 
noted, and lastly the Table Cases. The Table Cases are 
numbered 1 to 45, and contain a representative collection of 
the Australian Fossil Fauna and Flora, although by no 
means complete, on account of the limited space. To 
display an adequate Australian Fossil collection would 
occupy at least four times the space now allotted to it, and 
this could be drawn from material already stored in the 
Museum. 
The arrangement of the Table Cases is in numerical 
order, and from Sub-recent to Cambrian. This series 
contains many described and figured types, the former 
being indicated by a red disc (holotypes) and the latter by a 
green one (plesiotypes, paratypes, and lectotypes).
