Tracy, here's a picture of West Indian gherkins and the Mexican Sour Gherkins.

If you have these, they look pretty cool! Maybe even more useful than the Mexican Sour Gherkin.
Some articles seem to interchange the names, so yours may still be the Mexican Sour. Either way, they should be a lot of fun!
