Head long as broad. Snout triangular, little longer than eye. 

 Canthus rostralis distinct. Loreal region level, oblique. Tongue 

 ovoid, last third free, hind edge slightly emarginate. Vomerine 

 teeth in two small slightly oblique groups, well separated, and close 

 behind choanae. Interorbital little wider than upper eyelid. Tym- 

 panum obscure, apparently slightly less than half of eye. Skin 

 smooth above, also on throat. Belly and lower femoral region 

 granular. Fingers entirely free. Inner toes slightly webbed basally. 

 Disks about half of eye. Several metatarsal tubercles and one at

Great variation in color is noticeable in the seven examples from 

 this locality. The largest brownish down middle of back, streaked 

 irregularly on tubercles with dusky. Head brown above, upper 

 lip with short dark streaks. Limbs brownish above, front pair 

 paler, and hind pair each with three or four dusky cross-bars on 

 femur, tibia, tarsus and metatarsus. Lower surface of body and 

 sides whitish, latter formed in contrast as brown streak continues 

 back from eye including tympanum and fades out on front side of 

 belly. Several of the larger examples show a ruddy tinge on the 

 femoral surface closing against the groin and inner surfaces of femur 

 and tibia. Smaller examples all present less striking color-pattern, 

 especially on sides, which only slightly paler. In all dark cross-bars 

 on hind limbs conspicuous. One small example shows narrow pale
