White coloured Conus glans

[diocrisseashells1000]

Hello collectors,
I have here a species of C.glans. This are all found in just one small island in the Philippines (1984-86). I just want to know if anyone have this kind of coloration, or encountered a same specie in other collectors cabinet, and i was wandering if there is such an albino form of C.glans?
Any opinion, info, comments, resource reference you can give will be a great help.
