Melvill did not know the habitat of his species, as moreover the colour of two of the 

 specimens is not quite typical, I was in doubt about the identity, which has now been settled 

 by the author.

The only specimen is a dead shell, which has been agglutinated by a XcnopJwra, as 

 may be seen by a fragment of shell affixed at the canal. As Melvill (1. c.) had his specimens 

 from a depth of 1 5 fathoms, it is not probable that the Siboga-specimen has lived at so great 

 a depth, but that it has been washed clown, before the Xenophora employed it. Originally 

 described as a Fusies, Melvill located it in the genus Latirus, in the quoted volume of the 

 Proc. Zool. Soc. Lond. as "the columellar plaits (were) more distinct in subsequent examples 

 than in the type". The Siboga-specimen has 2 strong columellar plaits and one fainter one, so 

 I had easily recognized its generic position, without knowing its specific name.
