The genus has not yet been recorded from the New Hebrides. 

 Some have been ascribed to *' Lord Howe's island, New Hebrides," 

 but this particular island is the one lying between the coast of New 

 South Wales and Norfolk island, although another islet in the New 

 Hebrides bears the name of " Lord Howe." The present species is 

 allied to Palaina Montrouzieri, of New Caledonia, but of different 

 sculpture.

Hab. Espiritu Santo island. 



Only one specimen was obtained. This little shell is shaped like 

 Sykes' 0. conella, of which it may perhaps be considered a variety 

 or a fresh example; however it comes from a very distinct locality 

 and it may prove to be specifically distinct. 



18. Helicina Layardi Hartm. 



Hab. Espiritu Santo. All the specimens have a reddish band. It 

 is the form recorded by Mr. Mabille as H. Bairdi, and I am dis- 

 posed to share Mr. Sykes' opinion that it is simply a form v( II. sub- 

 Itzvigata Pfr. The sculpture is precisely the same, as described by
