thank you so much for the identification. Is there any published literature with you describing its characteristics? would be grateful if you can help!
I just checked with WoRMS Database and found that Metula santoensis does not exist as a valid name and the work carried out by Ladd in 1976 is from fossil shells. gastropods.com also shares the same information with and addition of Guido. S. Popes work of the shells of Philippine islands. So there is not much of a clarity. Metula mitrella is also close (accepted now as Metula metula). Please clarify.
