II. — Descriptions of new Reptiles and Batrachians from 

 Colombia. By G. A. Boulenger, F.R.S. 



The new Reptiles and Batrachians described below form part 

 of a collection made at Buenaventura, near the coast, and at 

 Cali, on the west slope of the Cordillera, at an altitude of 

 3200 feet, by Mr. W. F. H. Rosenberg. A selection from 

 the collection has been acquired by the Trustees of the British 

 Museum, including the types of the new species.
