Help Identifying Nautilus Shell

Hello.

I went to an auction and bid on a lot. Turns out there were three shells in the lot with a bunch of other miscellaneous items. A nautilus, and abalone and a MOP. I am trying to get more information on the nautilus because I know zero about them, not that I know that much more about the other two. Anyway, can somebody help me identify what I have in the photos? Most I have seen have black on them. I haven't found any without the black. I don't know if that means anything.

Thank you,

Vicki

Small FYI, the all white along the newest section (toward the opening where the animal was living) of the shell shows that it was an adult. Here is a link to an image showing the umbilicus difference between N. pompilius and N. macromphalus (scroll down the page and look to the right. Click on the image to get a larger display and more info. If you place your cursor on the names at the top, there is a popup that describes the umbilicus.
