Among the specimens in a small collection of reptiles and batra- 

 cMans recently made by Mr. A. H. Jennings on the Upper Peqiiini 

 River, Republic of Panama, there is a large, conspicuously colored, 

 and otlicr\s'ise remarkable tree toad, which has been generously pre- 

 sented to the United States National Museum. A scarcel}^ less 

 remarkable tree toad of another genus, and characterized b}^ the 

 erect spikes surrounding the crown of its head, was simultaneously 

 presented to our Museum by Mr. A. Alfaro, of the National ^luseum 

 of Costa Rica, together "wdth a less conspicuous, though not less mter- 

 estuig, new species of salamander. The last two species were collected 

 in the valley of the Orosi, Costa Rica, by Mr. C. Picado, for whom I 

 have named the salamander.
