FROGS OF COLOMBIA — COCHRAN AND GOIN 77 



Relictivomer and since we have had very little first-hand experience 

 with the other genera in South America, we follow him in the generic 

 assignment. We must say, however, that, to us, ovalis and pearsei seem 

 to be rather closely related, and in fact we must agree with Dunn 

 (1949, p. 13) : "I would take them for vicarious races save for the 

 statement of Ruthven that the two occur together at Fundaci6n."
