I am interested in buying shells from the Gulf of California region,
depending upon what is available.  I am not limited to Class, Family,
Species etc.  Are there any reputable dealers that may have a reasonable
inventory from this area?  From what I have seen on-line, most have a
only a smattering from the region, usually O. porphyria and not much
else.  Any guidance in this area will be greatly appreciated.
