'" Until new material is discovered in Mexico, the Mexican reports of Sphaerodactylus fantasfkus, an- 

 thracinus, punctatissimus (cinereus), and sputator, are to be regarded as uncertain. The type locality of 

 anthracinus is "Mexico," but possibly in error (see p. 213) . It would not be impossible for a part of these forms 

 to occur, as recent introductions in Mexico. Banana fruits serve as a ready means of transportation.
