BATRACHIANS FROM BOLIVIA 133 



This species appears to be nearest related to Cope's H. cir- 

 cumdata, which I only know from the description, but which 

 is distinguished by a stouter form in addition to its peculiar 

 markings. 



18. Hyla spegazzinii, Blgr. (4). 



19. Hyla laurina, Stdr. (7). 



20. Hyla venulosa, Laur. (2, 4;. 



21. Hyla nasica, Cope (2, 3, 5).
