I've encountered this problem a few times in the beginnings of my herp keeping. I had quite a few tanks already but without lids and finding the right ones was a pain. In aquariums there is generally 2 standard lid sizes, ones for "Hagen" tanks and ones for "Miracles" tanks. Both manufacturers produce same gallon size tanks so you have to try with both lids to find out which one you have. Obviously if you see a Hagen logo on the black rim, you have one question answered there.
What I did to make sure I had the right lids for all my tanks was I went to local shops that carried both types of lids, explained my situation and asked if it was ok to exchange the lid I had just purchased should it not fit. I never had a problem with this, brought it home and tried it, went to change it if it wasn't the right one.
Now I have so many tanks that if I need an extra lid I can try out the ones I already have to see what kind I need!
If the lids you have already purchased haven't been used, you can probably still exchange them for appropriate sized ones.
