ammiralis archithalassus or pseudocedonulli?

[ennss]

Any opinions on this shell?  Is it archithalassus or pseudocedonulli?    Picture could be better - there is coronation on the shoulder (white bumps), and it's 33mm.

Referring to these pages, I can't tell what the defining difference would be:

Do you know where it is from ?
I have Conus blainvillii (Vignard 1823) that looks like it in a book.

It's from Racha Island, Thailand.

If the shell is found in Thailand it is pseudocedonulli
