FROGS OF COLOMBIA — COCHRAN AND GOIN 141 



head. When arm is adpressed, tip of second finger reaches to end of 

 body; when hind leg is adpressed, heel reaches posterior corner of 

 eye; when limbs are laid along the sides, knee and elbow touch; 

 when hind legs are bent at right angles to body, heels slightly overlap. 

 Skin of upper parts smooth, except for some small transverse glands 

 on sacrum; venter smooth, except for weak granules below anus; a 

 bony ridge from posterior corner of eye ending above shoulder, and 

 followed by a large squarish gland just above arm insertion; a slight 

 skinfold across chest; a faint ventral disk; no external vocal sacs, but 

 forearm of male developed for clasping. 



Dimensions. — Head and body, 44 mm.; head length, 12.5 mm.; 

 head width, 11.5 mm.; femur, 18.5 mm.; tibia 19.5 mm.; foot, 17 mm.; 

 hand, 13.5 mm. 



Color in alcohol. — Dorsum cinnamon, uniform except for some small 

 scattered guanine spots; venter light ochre yellow, immaculate; 

 a few indistinct olive crossbars and spots on legs; upper lip, canthal 

 region, upper eyelids and gland above shoulder pale ochre. 



Remarks. — Some of the paratypes that are smaller and younger than 

 the type have rather elaborate patterns. In USNM 54191, from 

 Cerro Azul, Dari6n Province, Panama, the ground color of dull sage 

 green is nearly obscured by three very wide clove brown chevrons, the 

 point of the anterior one produced into a wide, dark interorbital 

 patch; similar dark crossbands nearly encircle the legs, being broken 

 for only a short distance on the lower femoral surface; venter olive 

 buff with a double row of small brown spots along its midline from 

 chin to posterior abdomen; canthal and loreal regions dark brown, 

 the rest of the upper lip olive buff. The Colombian specimens, none 

 of which seem to be very old, resemble USNM 54191 very closely, 

 except that the small brown dots on the belly are more scattered 

 ANSP 25626 lacks ventral spots. 



Usually the toes are about one-half webbed, but the webbing 

 appears to be more deeply incised in some individuals.
