Type, No. 19,593, A. N. S. P. Guapilis, Costa Rica. July, 1915. 

 D. E. Harrower. 



This species appears closely related to E. bocourti (Brocchi), 2 but 

 differs in several respects. E. bocourti has the partly circular tongue 

 entire, the tympanum one-third the eye, first and second fingers of 

 nearly equal length, toes with a rudimentary web, and arms and 

 legs marbled with brown above. 



(Humeralis, with reference to the dark blotches on the humerus 

 near the knee.) 



Dendrobates tinctorum (Keferstein). 



One example dull crimson-purple above, variegated with darker 

 markings. A small one beautiful dark crimson, marked with blackish 

 dots on the back and head above. Its lower surface is blotched with 

 blackish. Another larger example buff in general tint, marked or 

 speckled with blackish above, and upper surface of hind limbs, and 

 lower surface of same, blackish. Throat and belly pale buff, with 

 few scattered dusky specks. Altogether four, 13 to 22 mm., measured 

 from snout to vent. 



Rana caeruleopunctata Steindachner. 



Color in alcohol dark olive on back, with obscure small rounded 

 dull dark bluish spots down middle from between eyes to vent. 

 Blackish band begins on each side of snout near tip, extends back 

 below eye, broadens, includes tympanum and continues to groin, 

 edged very narrowly above its whole extent with whitish line. From
