from eye by an interval equal to one-half its own diameter. Fingers 

 rather long, with lateral ridges, free, first finger much shorter than 

 second, fourth longer than either and reaching to base of disk of 

 third, which is a little larger than the tympanum; a distinct oval 

 thumb pad present; a larger, bilobed palmar callus; metacarpal 

 tubercles well developed. Toes moderately long, not webbed (or with 

 barely a trace of web), third toe much shorter than fifth, the disk of 

 which reaches base of antepenultimate phalanx of fourth; disk of 

 fourth toe a little larger than tympanum and equal to that of third 

 finger; a rather small oval inner metatarsal tubercle and a minute, 

 scarcely distinguishable outer one; a tarsal ridge ending midway to 

 heel; a distinct skinfold on heel and knee. Body rather stout, in post- 

 axillary region nearly equal to greatest width of head. When hind leg 

 is adpressed, heel reaches a point between eye and nostril; when limbs 

 are laid along the sides, knee and elbow overlap; when hind legs are 

 bent at right angles to body, heels overlap. Skin of upper parts finely 

 granular, with some coarser granules on sides and sacrum; venter 

 coarsely granular except for throat and chin, which are nearly smooth; 

 a low glandular ridge from posterior corner of eye above tympanum, 

 ending above corner of mouth; a distinct skinfold across chest; a 

 faint ventral disk; apparently external lateral vocal sacs in the male. 



Dimensions. — Head and body, 28 mm.; head length, 10 mm.; 

 head width, 11 mm.; femur, 12.5 mm.; tibia, 14 mm.; foot, 12 mm.; 

 hand, 8.5 mm. 



Color in alcohol. — Dorsum smoke gray, with a wide sepia )-(-shaped 

 band across the shoulders, its anterior prolongations extending to 

 posterior border of eye and its posterior ones continued as a diagonal 

 lateral stripe across the side, fading out there; an indistinct drab 

 crossbar between the eyes, and a drab stripe along can thus; upper 

 lip smoke gray with two sepia spots from lower eyelid to upper lip; 

 a narrow sepia line following ridge above and behind tympanum; 

 lumbar and sacral regions indistinctly mottled with drab; three wide 

 sepia crossbars on tibia, continued less distinctly over femur and foot; 

 an indistinct dark triangular postanal patch; posterior femur drab- 

 gray with a few darker spots; venter hair brown, immaculate except 

 for some small sepia spots around edges of lower jaw and on chest; 

 soles of feet and palms of hands immaculate hair brown. 



Remarks. — Dr. P. Kuenzer very kindly loaned to us Werner's 

 syntypes of Hylodes affinis, which are still in good condition. The 

 smaller syntype, from the Paramo de Bogota, was taken on the road 

 to Choachi on January 27, 1897, by Dr. Otto Burger; actually, it is an 

 immature frog of the species E. bogotensis, as Dr. Dunn has stated 

 (1944a, p. 72). Its adpressed heel reaches only to the center of the eye, 

 and its critical measurements lie well within those of numerous other
