I'm just learning herp identification as a side-hobby to my birding, and am hoping for help. I was recently in Victoria Falls, Zimbabwe and saw a very small frog inside the main park that I could not identify. It was about the size of a fingernail, with a thin yellow stripe, and several were hopping in the areas close to the edge where the mist was falling. (I also saw what I believe was a striped skink, Mabuya striata; I had a reptile book but it does not include amphibians). Thanks for any guesses, links to pictures, etc.
