FROGS OF COLOMBIA — COCHRAN AND GOIN 397 



femur with smaller black spots, the upper ones more or less alternating 

 with the black femoral bars; tibia dusky russet above, with black 

 bars which are smaller than those on femur; inside of tibia fawn color 

 with small alternating dark spots; knee dull russet, the dark bars 

 narrowed near it but emphasizing its outlines; venter tawny ochrace- 

 ous, with some small gray dots on throat, chest, and lower limb sur- 

 faces; a series of dark crescentic marks around rim of lower jaw; side 

 of head dull russet, with a black line just below can thus widening over 

 nostril and reaching upper lip near tip of snout; two wide black bars 

 from loreal region or eye to upper lip; soles of feet and palms of hands 

 clove brown, the tubercles and disks dull russet. 



Remarks. — The rounded black spots along the side of the body, 

 becoming larger in the groin, occurring on the anterior and posterior 

 surfaces of the femur and on the inside of the tibia, permit ready 

 recognition of w-nigrum. The black W from which the specific name 

 was derived is noticeable between the shoulders in some young indi- 

 viduals. Apparently this fades considerably, as it is scarcely visible 

 in the older specimens at hand. The venter is sometimes immaculate, 

 or some dusky dots may appear all over, or may be limited to the 

 chin and throat. A series of small dark semicircular spots sometimes 

 surrounds the rim of the lower jaw. While possessing the same glands 

 across the back behind the head as in nearly all eleutherodactyli, 

 these glands are not emphasized by a very dark color patch as they 

 are in ranijormis and longirostris; however, whenever the dark W- 

 mark is strong it includes these glands.
