FROGS OF COLOMBIA — COCHRAN AND GOIN 21 



specimens at hand, its position in the genus Dendrobates is accepted 

 here. 



Three tadpoles (USNM 144985) that possibly are of this species 

 were collected at Volcanes, Caparrapi, Cundinamarca, by E. R. Dunn 

 on October 20, 1943. The largest one measures 7 centimeters in head 

 and body length and 11 centimeters in tail length; the respective 

 measurements of the smallest one are 6.5 and 9.5 millimeters. 



The first finger is slightly to distinctly shorter than the second in 

 nearly all of the adult examples at hand. The adpressed heel may 

 reach to the center or the posterior corner of the eye or, rarely, only 

 to the tympanum. 



Sometimes, in preservative, the light markings no longer are 

 apparent, and the whole body appears slate-colored or blackish. 

 Such examples closely resemble D. trivittatus, which also is often 

 very dark after preservation; however, the long first finger in trivit- 

 tatus and the much shorter one in lugubris should serve to differentiate 

 the two. Dunn previously had identified USNM 48865 from Truando 

 as "auratust," but that specimen appears to be more like the all- 

 black lugubris. 



One specimen (USNM 145098) still has traces of primrose yellow 

 on the light dorsolateral lines and on the light areas on sides and 

 jaws; other examples (USNM 145099-100, 145102-3) are pale Nile 

 blue in those areas.
