The least-explored portion of the S. American continent, and 

 where I imagine most novelties are still to be met with, is the coun- 

 try lying to the west of the great range of the Andes in the repubUcs 

 of New Grenada and Ecuador. Below the Gulf of Guyaquil the 

 western watershed of S. America becomes very much narrowed, and 

 the country, being almost rainless, is arid and comparatively devoid 

 of vegetation ; but to the northward of this, beneath the perpetual 

 precipitation which takes place under the Equator, the vegetation is 

 as luxuriant and the forests as interminable as upon the eastern slope 

 of the range. Along the coast of this region little has been done in 

 the way of obtaining zoological specimens. During the voyage of 

 Capt. Kellett in H.M.S. 'Herald,' a certain number of animals were 

 collected in the Bay of Choco and upon the island of Puna in the Gulf 

 of Guyaquil, which are now in the British Museum, and the indefati- 

 gable traveller Delattre also collected a little around Buenaventura, 

 and penetrated into the interior by this route as far as Popayan and 

 Pasto, but on the whole we are very little acquainted with the 

 zoology of this interesting country. 



Farther southwards in the vicinity of Quito we are more fortunate.
