head width, 7.2 mm.; femur, 11.3 mm.; tibia, 12 mm.; heel-to-toe, 15.4 

 mm.; hand, 6 mm. 



Color in alcohol. — Lavender above, pale below. The dorsal lavender 

 color fades gradually along the side with no sharp line of demarcation. 

 The dorsal ground color is absent from the margin of the upper lip. 

 On the limbs the dorsal color is developed as follows: on the forelimb 

 it is present on the upper surfaces of the upper and lower arms, the 

 hand, and fingers three and four, including the tip of the disk of 

 finger four; on the hind limbs the pigment is present in the upper 

 surface of the thigh and shank, the foot, and fingers four and five, 

 out to and including the top of the disks, and there is a trace of 

 pigment on top of third toe. The ventral surfaces of the body and 

 limbs are immaculate. 



Remarks. — This form is certainly closely related to Centrolenella 

 buckleyi. After examination of 16 specimens of buckleyi ranging from 

 Venezuela to Ecuador, the only characters that seem to maintain 

 antioquiensis are the more extensively developed webs between the 

 fingers and the more heavily developed spine on the humerus.

Diagnosis. — A centrolenid without vomerine teeth; with a web from 

 the middle of antepenultimate phalanx of third finger to base of 

 penultimate phalanx of fourth; tympanum present but somewhat 

 indistinct; dorsal ground color purple with a sharp line of demarcation 

 between the dorsal and ventral ground colors. 



Centrolenella buckleyi can be distinguished from all Colombian 

 centrolenids except antioquiensis, fleischmanni, and johnelsi by the 

 absence of vomerine teeth. The absence (usually) of well-developed 

 humeral spines, the lack of a sharp line of demarcation between the
