Amphibians and Reptiles from Porto Rico and the Virgin Islands. 5 



irregularly spotted or blotched with whitish on the back, about the inter- 

 orbital region, and at each heel. A few spots may also occur elsewhere on the 

 upper surfaces of the tibial regions. The smaller examples have large obscure 

 blotches of slightly darker shade than the general color of the upper surface, 

 which tend to form obscure bars across the tibial and femoral regions. The 

 lower body-surface is similarly variable, from slightly soiled brownish to more 

 or less completely marbled with smutty, in which case there is also a median 

 obscure pale line from the chin to the sternum, with line given off each side 

 to the axillaries. 



Fio. 2. Eleutherodactylus auriculatus (Cope). A to D, variation in dorsal color pattern 

 of adult examples from Arecibo and Tanama River Junction.
