(1) I have various shells with the only data as "tangle net," and we know that does not give us an exact location; Mactan, Cebu is only a clearing house, as I understand it. Howewver, I have some different listings as to depth. Can anyone give me the RANGE of the depth? (2) Funny someone would mention Iluminado Iway. I too got shells from him twenty or so years ago. I had some cones (and I may still have a few; I may have sold or traded them since cones are not my thing, except for a dozen or so that are so incredibly beautiful no one could resist them). At the time, the most knowledgable cone person in our club said he thought they were a form of magus. I wish I had a scanner and could post the image of one, if I can still find it.
