The following species are based upon specimens which form part 

 of a very valuable donation of shells from various localities, pre- 

 sented to the British Museum by Mr. John Brazier of Sydney, by 

 whom the National Collection has over and over again been enriched 

 with very many new and interesting forms of Mollusca and other 

 branches of Zoology. 



Most of the specimens have been collected by Mr. Brazier 

 himself, and consequently are accompanied by precise information 

 respecting their localities.
