with the lower jaw rimmed with black; a large black spot occurs on 

 center of throat, and there are some fine scattered short black lines on 

 the belly. The femur and tibia are black below, the black area having 

 an irregular margin. The feet and hands are black above and below 

 except for the disks and tubercles, which are smoke-gray. A narrow 

 black ring extends around base of arm and leg, widening in axilla and 

 groin, and merging on the femur with the black of the lower surface. 

 An irregular black crescentic mark occurs just above the arm and some 

 distance behind the tympanum. The upper lip has a spot of bright 

 geranium pink below the eye, preceded by a vertical black spot. 

 The tip of the snout, canthus, and nostrils are irregularly black- 

 spotted. Several other frogs from the same place show some pink color. 

 Those spots that have faded to gray have the appearance of lichens, 

 as the small irregular black marks occur at random over the upper 

 surface. 



Remarks. — Specimens in the series ANSP 25349-52, from La 

 Guayacana, Narifio, are said by Funkhouser (1956, p. 75) to be 

 intermediate between confluens and sylvaticus (from nine kilometers 

 west of Santo Domingo de los Coloradas, Pichincha Province, in 

 northwestern Ecuador) but to be closer to the former. In addition to 

 these specimens mentioned by Funkhouser, three others (CNHM 

 61772-3, 61775) from La Guayacana have been similarly identified by 

 the present authors. 



The most noticeable structural difference between D. t. confluens and 

 D. t. tinctorius is the significantly longer foot of the former, whose head 

 width and tibial length also appear to be slightly greater.
