@Ten specimens from southwestern Costa Rica . 
’ Seven specimens. 
¢ Among specimens from Boruca are some that I can not distinguish from typical 
D. sancti-thomex; 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.
