FROGS OF COLOMBIA — COCHRAN AND GOIN 415 



examples of bogotensis at hand. The lectotype differs from the smaller 

 syntype, and the two obviously are not of the same species. The name 

 affinis is retained for the lectotype and other examples. The lectotype 

 has a large frontoparietal depression, and in this respect is similar 

 to lehmanni. Its legs are longer than those of bogotensis, as its adpressed 

 heel reaches between the eye and the nostril, while in bogotensis the 

 heel seldom extends farther than the center of the eye and often only 

 to the tympanum. The color patterns also are quite unlike, as affinis 

 has large dark squarish dorsal spots prolonged on the side (at least in 

 the lectotype) as oblique dark lines, while bogotensis usually has a 

 conspicuous pale (crimson in life) area on the side and on the front of 

 the femur. The largest example of affinis at hand (CNHM 81882) 

 measures 31.5 millimeters, while the largest specimen of bogotensis is 35 

 millimeters in length. The greatest difference between the two species 

 seems to be the lack of a perceptible frontoparietal depression in the 

 latter, although the frontoparietal area is hollowed out a little, as in 

 most eleutherodactyli of this group. 



Two specimens, USNM 118727-8 (formerly MZUM 63777) from 

 Magdalena, were identified at the Museum of Zoology, University of 

 Michigan, as affinis, They have the frontoparietal depression but 

 the bodies appear more elongate and the toe disks a little larger than 

 in typical affinis. No color pattern is now apparent. 



Specimen CNHM 54412 is quite similar in bodily proportions to the 

 lectotype but differs in several respects. It has a dark brown venter 

 with large light round spots all over the belly and the throat is some- 

 what lighter. Its heel reaches only to the center of the eye. Its tym- 

 panum is distinct but is much smaller (only about one-fourth the 

 diameter of the eye) than that of the lectotype. Its venter is nearly 

 smooth, although some very weak granulations across the chest are 

 discernible. It has a similar dorsal pattern, that of a wide W across 

 the shoulders, but it has two or three light diagonal curving lateral 

 stripes not noticeable in the lectotype. 



One of the Medina examples, MLS 84, has a wide white middorsal 

 stripe, and the shoulder markings are reduced to a pair of slanting 

 brown spots marking the glands.
