- ↑ Ten specimens from southwestern Costa Rica.
- ↑ Seven specimens.
- ↑ Among specimens from Boruca are some that I can not distinguish from typical D. sancti-thomæ; in fact, while the difference of coloration in the two forms is quite obvious when extreme examples are compared, the absence of strict corellation between the color-differences and geographic distribution is difficult to understand.
