Shell Identification

[jonicat]

I was recently left a shell collection but am clueless about these shells.  Alot of the shells have slips of paper from a seashell museum showing a name and source.  When I search for the names on the internet to find out about them, part of the name comes up but I can never find the full name.  Below are 3 examples.  What I need to know is if the name on the paper is the "Real" name or should I go by the one name that comes up when I search.  I was going to send pictures but I don't see anything that tells me how to insert a picture here.
1.  Lambis Arthriatica  Source: Red Sea
2.  Strombus Pinuatus? (Not sure if spelling is correct) Source:  Cibu (These are written in handwriting Not sure on spelling)
3.  Lambis Scorpio  Source:  Albay Gulf
Thank you for any help you can give.
