This species was originally described from Porto Rico. It has also 

 been reported from Haiti, St. Kitts, Dominica and Mexico. The 

 Mexican specimens, supposed to be liliaceus, have been referred 

 to D. sulphureits by Dr. von Martens, in my opinion correctly. That 

 species is thinner than liliaceus, with the body whorl more tapering 

 below the base in liliaceus being decidedly convex, and the texture 

 solid and cretaceous in adult specimens. Numerous specimens are 

 before me from Porto Rico, but I have seen none from Haiti, St. 

 Kitts or Dominica.
