  1. These both look like Anolis cristatellus to me. Without having them in hand, it is difficult to definitively exclude A. gundlachi, but my money is with A. cristatellus. Any more information on locality?

    The color pattern of the first animal is pretty & it is one that we have seen on A. cristatellus.

  2. Thanks for your help with this i.d. Our hosts asked me for copies of these photos, and we hoped to include the species name as a caption. We were in a guesthouse on Rt. 149 a few miles north of its intersection with 533.
