The large collection of amphibians from the Sierra Nevada 

 de Santa Marta, Colombia, in the Museum, contains a series 

 of specimens of Hylodcs cnicntns Peters^ which illustrates 

 rather fully the life-history of the species. A part of this 

 material was gathered by the writer, who had an opportunity 

 to study the form in its environment while a member of the 

 P)ryant Walker Expedition sent to the region by the Museum 

 in 1913, and a part was collected by M. A. Carriker on April 

 24, 1914. 



Th.e specimens obtained are from two localities, San 

 Lorenzo and the heights east of San ^Miguel, the former col- 

 lected bv the writer, the latter by Carriker. On San Lorenzo 



1 For the identification of the specimens the writer is indeljted to Dr. George 

 A. Boiilenger, of the British Museum.
