corner of eye; when limbs are laid along the sides, knee and elbow touch; when

 6.5 mm.; femur, 9 mm.; tibia, 10 mm.; foot, 9 mm.; hand, 6 mm. 



Color in alcohol: Dorsum pinkish buff, powdered everywhere with minute dark 

 dots; a drab crossband between the eyes; a pair of short, dark ) (-shaped lines from

lip below anterior corner of eye; a white Y-shaped mark on front of snout, the 

 upper branches extending along canthus to eye; 2 or 3 faint diagonal crossbars on 

 forearm, a larger dark patch on elbow and a short mark on anterior part of upper 

 arm; femur, tarsus and foot with minute dark dots above; posterior femur im- 

 maculate; a dark knee patch; tibia with 3 faint crossbars. Venter pale buff,

Remarks: The largest male has a total length of 21.5 mm.; the single female 

 measures 23 mm. The silvery spot on the upper lip which characterizes this 

 subspecies is very distinct in all except one frog, where only a trace of the marking 

 appears. A similar white spot in the same place appears in another member of 

 the group of minute frogs, a subspecies which I named Hyla bipunctata hranneri, 

 from Pernambuco (Journ. Washington Acad. Sci. v. 38, No. 9, 1948, p. 316).
