This species should be regarded as the type of Bolten's genus Astram.,* since (as 

 i'/H/ix, Gmelin) it heads the species he quoted.

The type of L. mnm-itinnii, figured by Delessert, was an inch long, but the New 

 Zealand form of the species, according to Suter, does not exceed half that length. 

 However, beyond this difference in size, there do not appear to exist any features 

 by which they can lie separated. L. unifasciata, Gray ; L. diemenensis, Quoy and 

 Gaimard ; /,. /n-iifn, Menke ; and L. antipodum, Philippi, are synonyms.

The name vittata, Huttou, has been discarded by Murdoch and Suterf on the 

 ground that Lamarck had already used that term for another species. Since, however, 

 1 have failed to find any reference to such a species, either in Lamarck's or any other 

 author's writings, I here adopt Button's name, which has eight years' priority over 

 Watson's carlottoe. 



Mr. Hedley's observations J upon the " Challenger " specimens are altogether 

 incorrect with regard to two out of the four specimens probably being from Bass 

 Straits. The two shells referred to are examples of T. xi/iiinn'tri<-<t, Huttou, and 

 doubtless were dredged with the two other specimens on the same tablet in Queen 

 Charlotte Sound. The shell from East Moncoeur Island, Bass Strait, quoted by
