The series of beautifully presei'ved Batrachians and Reptiles brought together by him during the first few months of his stay in the Choco, Colombia, and presented by him to the British Museum, is one of great interest and shows how much remains to be done in the exploration of that part of South America. Unless otherwise stated, the specimens are from Pefia Lisa, Condoto, altitude 300 feet, Within the last few years, series of Batrachians and Reptiles brought together by Mr. M. G. Palmer in the same district had been acquired by the Trustees of the British Museum and fui-nished the types of several new species described by me %■ They showed a close agreement with the fauna of N.W. Ecuador, for a knowledge of which we are indebted chiefly to Mr. Rofsenberg § — an agreement which is furtlier exempli tied by Dr. Spurrell's collection. * Published by permission of the Trustees of the British Museum. t For explanation of the Plates see p. 1038.
