character to those of tNpical forms of Charonia. Eeyond a few words 

 descriptive of the raduhi by the same autliors nothing is known of 

 it, and consequently one cannot compare it with the radulae of 

 ' Tritonium nodiferum ' and ' T. variegatum ' as described and 

 figured by Troscbel.' It is therefore simply on conchological 

 characters that I now place this species in the genus Charo7iia. 

 In a specific point of view this species has been nioi'e fortunate, 

 having only twice receiver! a trivial name. 



Perry in 1811 was the first to describe it under the name Biplex 

 ausfralasia, and then Lamarck in 1822 designated it Eanella leucostoma, 

 under which name it was commonly referred to until attention was 

 directed to Perry's work by Mr. Hedley* in 1901, and since that date, 

 with one or two exceptions, the name australasia has been accepted. 

 In following tliis general practice I suggest emending the word by 

 adding a terminal na, and thus making it a proper qualifying term, 

 uustralasiana.
