than first but considerably shorter than fourth; the swollen basal part 

 of first finger mergmg with the indistinct metacarpal tubercle; small 

 but distinct subarticular tubercles; toes fully webbed, the tips very 

 slightly dilated, third and fifth subequal, reaching halfway on pen- 

 ultimate phalanx of fourth; a small spurlike inner metatarsal tubercle 

 but no outer one; subarticular tubercles of toes small but distinct; a 

 strong inner tarsal fold reaching almost to heel, and a similar ridge 

 along margins of outer toes. Body fairly stout. When hind limb is 

 adpressed, heel reaches well beyond tip of snout ; when limbs are laid 

 along the sides, knee and elbow greatly overlap; when hind legs are 

 bent at right angles to body, heels are widely separated. Skin of head 

 smooth, of back and sides coarsely granular, of upper limb surfaces 

 nearly smooth with a few scattered pustules on tibia and some gran- 

 ules on upper femur; a slight supratympanic ridge; belly slightly 

 granular anteriorly, nearly smooth posteriorly; lower limb surfaces 

 smooth. Chin of male much wrinkled due to the presence of the large 

 median vocal sac extending across the throat. 



Dimensions. — Head and body 45.5 mm.; head length 14.5 nam., 

 width 17.5 mm,; femur 28 mm.; tibia 25.5 mm.; foot 24.5 mm.; 

 hand 14 mm. 



Mathematical analysis (in percentage of the total length) : 



Color in alcohol. — This specimen has faded to russet above, buff 

 below, with only slight traces of the dark leg stripes found in fresh 

 specimens. Other freshly preserved examples from Lassance show 

 the dorsal groimd color to be olive-gray, Hghtening on the limbs; a 

 narrow black line runs along canthus from nostril to eye ; three or four 

 elongate dark spots occur on either side of the midline of the back, the 

 anterior being partly on the upper eyelid, the second the largest, the 

 last two often broken up. Small black spots are scattered over the 

 throat and sometimes on the belly. Heavy dark stripes occur not 

 only on the posterior femur but also inferiorly and anteriorly, with 

 slighter continuations on the tibia. The subarticular tubercles of the 

 toes are often gray or black. 



Variations. — In a fine series of 28 examples from Lassance, a rela- 

 tively slight degree of variation is found. The femur is very long in
