The Australian region comprehends for him three principal 

 sub-regions — 



1. The Austro-Malaysian, comprising the group of the 



Moluccas and that of New- Guinea. 



2. The Australian, properly so-called, comprising Australia 



and Tasmania. 



3. The Polynesian, extending to the east as far as the 



Gambier Isles and the Marquesas, to the west to the 

 Solomon Isles and to the Mariannes, to the exclusion of 

 the Sandwich Isles. New Zealand should form an inde- 

 pendent group. 

 The Polynesian fauna numbers 60 species, and that of Aus- 

 tralia 310, whilst there are nine species only common to the 

 two sub-regions. 



The number of genera in Australia is 76, of which 10 are 

 peculiar. The geographical distribution of the species is as 

 follows : — S.W. Australia, 47 ; N. Australia, 17 ; Queensland, 

 112 ; S.E. Australia (New South Wales), 82 ; S. Australia 

 (Victoria, Tasmania, and S. Australia), 122. Five species from 

 Port Augusta are included in S.W. Australia ; and the neces- 

 sary correction will reduce the number of Western Australian 

 species to 42, and raise that of Southern Australia to 127. 

 The number of species determined from South Australian 

 specimens is 24, belonging to 14 genera. Mr. Tepper, in his 

 census published by the Society last year, gives 26 species of 

 5 or 6 genera. 



One of the new genera instituted by M. Fauvel, uniquely 

 represented by a South Australian species, is named Correct — 

 a denomination already occupied for a well-established group 

 of B,utaceous plants, a familiar example of which is Correct, 

 speciosa. As under these circumstances a dual employment of 

 the cognomen will prove of inconvenience, I have been bold to 

 suggest that of Fauvelia for the genus of beetles. 



The plan of the work is excellent. Under each natural 

 group is a synoptical table of the characters of the genera, and 

 under each genus that of the species. Each genus and species 

 is fully described ; the diagnoses are in Latin, but the remainder 

 of the text is in French. The work is not illustrated.
