Unknown bufonid from Pearl Lagoon, Nicaragua.

I have been trying to figure this toad out for quite a bit. I looks similar to Bufo coniferus but also Bufo valliceps. I don't think it's either. B. coniferus that I have seen tend to be smaller (this was a large toad) and more lanky, and while I have no experience with B. valliceps, my friend does and has photos of it that doesn't look quite right to me.
