lected in Villavicencio, Meta, during his visit of 1943-1944. Hno. 

 Niceforo Maria has sent eight other examples from the same locality, 

 and these resemble Dunn's specimens closely, all of them seemingly 

 indistinguishable from the Bogota frogs. 



A dark stripe or series of spots nearly always is present on the 

 anterior femur. Above this the top of the femur may be pale to medium 

 brown, immaculate or with a few small dark dots. The posterior 

 femur may have a continuous dark stripe like that on the anterior 

 surface, or a series of irregular dark markings, or many heavy or 

 medium spots. The light dorsolateral stripe beginning behind the eye 

 is wide and distinct on nearly all examples, and it slants downward 

 from above the level of the elbow, ending in the groin. The dark area 

 bordering it above is narrow and often broken up into spots anteriorly. 

 The sides are dark, this area being quite wide and ending in an ir- 

 regular border along the sides of the body. 



Some frogs (USNM 151127-79) from Purace, Cauca, suggest 

 subpunctatus in many characteristics but vary slightly from Meta and 

 Cundinamarca examples. Their critical measurements agree except 

 for foot length, which is less in the Cauca frogs. The largest example 

 in the Cauca series is 23.5 millimeters in length. The skin is not 

 abraded in any specimen in the series. Some examples have a few 

 large conical tubercles above the knee and on the upper surface of 

 tibia and foot. The toes are unwebbed in 18 adults, slightly webbed 

 in 20, and with webs almost one-eighth the length of the fourth toe 

 in three. The first and second fingers are subequal in 24, while the 

 second finger seems to be slightly longer in 18. The heel extends no 

 further than the tympanum in eight and to the center or to the 

 posterior or anterior corner of eye in 33. 



The belly is more or less granular, the back practically smooth, 

 and the toes webbed at the base (although sometimes very slightly) 

 in the 48 examples at hand from Cundinamarca and Meta. The 

 coefficient of variation in all critical measurements falls between 5.4 

 and 7.9 in these examples. The heel reaches between the shoulder 

 and the posterior corner of the eye in 74 percent of the frogs, to the 

 center of the eye in 24 percent, and to the anterior corner of the eye 

 (in only one case) in 2 percent. 



The venter may be immaculate pale buff or light olive, but some- 

 times a rather concentrated dark spotting appears on the posterior 

 half of the belly and on the under surface of the femur, while again 

 only a few dark spots may show, mostly near the lateroventral area 

 and along the midline of the lower femur. 



An example from Bogota mentioned by Boulenger (1882a, p. 194) 

 as having been identified by Giinther as Liuperus elegans Peters has 

 been loaned to us by the British Museum (BM 68.3.4.7). Its color is
