half, and the throat spots sometimes are arranged beside a median 

 light stripe down the center of the throat. E. raniformis, on the other 

 hand, has an immaculate belly and throat, with perhaps some small 

 dusky spots around the edge of the lower jaw. 



Both conspicillatus and longirostris have unusually sharply outlined 

 dark triangular postanal patches, although these are paler in some 

 individuals. No distinct dark postanal patch occurs in raniformis, but 

 the area behind the anus is often darkened. Dark parallel diagonal 

 bars occur on the upper proximal surface of the femur and on the 

 knee in conspicillatus and raniformis, while the spots in that region in 

 longirostris are not usually so regularly placed. 



Two or three very dark circular spots surround the glands situated 

 behind the ear to well above the arm insertion in longirostris. In 

 conspicillatus and raniformis usually only the inner, uppermost gland 

 is dark, and often the glands are no darker than the rest of the dorsal 

 skin. 



All three forms have the disks on the first and second fingers much 

 smaller than those on the third and fourth fingers, unlike w-nigrum, 

 which has the disk of the second finger about as large as that of the 

 fourth finger and the disk of the first finger not unusually small. 



Two frogs (CNHM 54352-3) from La Selva, Pueblo Rico, Caldas, 

 have dorsal markings very similar to those of the figured type of 

 Boulenger's achatinus, but these specimens have the toes one-eighth 

 webbed, have the heel reaching beyond the snout, and show numerous 

 other differences in bodily structure from typical achatinus; hence, 

 they have been identified tentatively as conspicillatus.
