HERPETOLOGICAL NOVELTIES. 

 BY T. BARBOUR AND E. R. DUNN. 



Most of the new forms described in this paper were collected 

 by the junior author during a journey to Costa Rica in the 

 summer of 1920. A few other new forms are recognized which 

 have been for some time awaiting description. 



The journey to Costa Rica was made far more pleasant and 

 profitable than it would otherwise have been by the excellent 

 hospitaUty and helpfulness shown by the resident officials of 

 the United Fruit Company and by Dr. Anastasio Alfaro of the 

 Museo Nacional in San Jose. The Doctor kindly allowed us 

 to study and retain some most interesting specimens which had 

 been brought from many parts of the republic. The following 

 localities were chosen for collecting stations : 



Zent — about twenty miles inland from Port Limon, 100 feet 

 elevation. Banana and cocoa farms, small pastures and some 

 rain forest. 



Monteverde — 200 feet. Same general conditions as Zent. 



Guapiles — 1,000 feet. Second growth forest and large pas- 

 tures. End of railroad, north of Mt. Turrialba and Mt. Irazu. 



Navarro — 3,368 feet. Orange farm of United Fruit Company 

 south of Cartago. Mountainous country. Collections were 

 made in the forests up to 6,000 feet. 



Volcan Irazii — Collected in the oak forest belt on this moun- 

 tain at elevation of 8,000-9,000 feet. 



Volcan Poas — Collected in the mixed forest at 7,600 feet and 

 in the clearing around the "Hotel de Poas" at about the same 

 elevation. 



Orotino — Station of the railroad about 10 miles from the 

 Pacific Ocean. Inner edge of coastal plain 900 feet. Dry woods 

 and farms.
