32 U.S. NATIONAL MUSEUM BULLETIN 288 



Dimensions. — Head and body, 35.5 mm.; head length, 11.5 mm.; 

 head width, 10.5 mm.; femur, 13 mm.; tibia, 15 mm.; foot, 12 mm.; 

 hand, 10 mm. 



Color in alcohol. — Dorsum olive-buff, with several irregular sepia 

 spots on the back; top and sides of head and snout immaculate; 

 upper limb surfaces olive-buff, with an irregular sepia crossband on 

 femur, another on distal part of tibia, and two or three fainter ones 

 on outer part of foot and across upper arm and forearm. Venter clove 

 brown, the borders of the lower lip fading to drab; an indistinct sepia 

 band across the chest; lower limb surfaces clove brown to sepia, with 

 a pale drab spot covering outer and lower part of knee; palms of hands 

 and soles of feet dark sepia, their disks and tubercles fading to wood 

 brown. 



A note with specimen BM 1915.10.21.52, from Andagoya, states 

 that in life the color was "above merging shades of orange and yellow; 

 below dark to black brown." 



Remarks. — The varied dorsal pattern of D.t. chocoensis suggests a 

 "clown suit" of very irregular dark spots on a light ground. Usually 

 the sides and sometimes the chest are light, while the belly is black. 

 The dark dorsal spots are different in size and arrangement in all 

 specimens. Usually the snout is light, although it may have a dark 

 spot in the center or on one side of it. The arms and legs often are 

 light above, but most of the Pen a Lisa and Rio Condoto examples 

 have dark spots or bands on the limbs. 



This subspecies tends to have a proportionately shorter tibia and 

 hand than the other Colombian forms in the tinctorius group. D.t. 

 vrittei also has a fairly short tibia, but it can be easily distinguished 

 from D. t. chocoensis because of its dark dorsum with small evenly 

 scattered light spots.
