of head very smooth; posterior part of eyelid with tubercles; 

 loreal region with very slight tuberculation ; a dim fold con- 

 necting posterior corners of eyes; a distinct dorsolateral glan- 

 dular fold from eye, continuing two-thirds the length of body; 

 a stronger supratympanic fold, separated from the dorsolateral 

 fold, goes from eye to insertion of arm, forming an obtuse angle 

 above tympanum ; a slight ridge on posterior part of lower jaw 

 continuing in a straight line to arm as a glandular fold, sepa- 

 rated from supratympanic fold posteriorly by a narrow groove; 

 skin on anterior part of body nearly smooth; skin on posterior 

 part of back and upper surface of tibia covered with numerous 

 minute tubercles with occasional larger ones; certain of those 

 in middle part of back arranged in two longitudinal rows ; chin, 

 throat, breast, belly, and underside of limbs entirely smooth; 

 fingers terminating in small rounded knobs, first finger dis- 

 tinctly longer than second but scarcely reaching penultimate 

 tubercle on third; subarticular tubercles moderate, carpal 

 tubercles rather indistinct; toes about four-fifths webbed, the 

 web reaching a short distance below tip of third, and slightly 

 beyond penultimate tubercle on fourth; subarticular tubercles 

 strong; inner metatarsal tubercle elongate, little more than one- 

 third the length of first toe; toes with small knobs at tips; no 

 outer metatarsal tubercle; a distinct skinfold on outer side of 

 fifth toe; a slight fold from metatarsal tubercle to near keel; 

 hind limb brought forward tibiotarsal articulation reaches to 

 nostril. 



Color in life. — Above gray-lavender with very dim darker 

 markings; a dark loreal streak and a large dark spot from eye 

 to arm involving tympanum; three large spots on upper and 

 lower lips; a dark spot above insertion of arm; limbs barred 

 full length; posterior aspect of femur dark purplish with a 

 longitudinal yellow streak ; a yellow streak on the glandular fold 

 behind angle of jaws; underside of forearm very dark with a 

 row of very small yellow dots; chin and breast dusky, mottled 

 with purple; underside of hands and feet purplish; a small 

 yellow spot between and slightly anterior to eyes. 



Variation. — The chief variation noted is in color. Certain 

 specimens have the body brownish lavender with islandlike spots 

 over the entire back; some have a V-shaped mark on the 

 shoulders. The strong tympanic spot is invariably present and 

 is usually very sharply defined, especially in young specimens. 

 There are usually some deep black spots in the groin. The loreal 

 streak is constant.
