2 Mr. C. Chubb on Birds from [Ibis, 



as possible, o£ the mammals of the northern portion of the 

 South American Andes, but, with his usual generosity, he 

 allowed Simons to collect birds also during his journey. 

 The specimens thus collected by Simons were acquired by 

 the British Museum and form a particularly welcome 

 addition to the Bird-E,oom, which had previously been poor 

 in specimens from the Andean regions. Ornithologists 

 who make a special study of the avifauna of South America 

 will, therefore, be grateful to Mr. Oldfield Thomas for his 

 patriotic action in thus enriching the National Collection. 



There are, however, two other collections included in 

 these notes, — one from the Andes of Ecuador, made by 

 Mr. Walter Good fellow and presented to the British Museum 

 by Mr. E. J. Brook ; and the other from Trujillo in north- 

 west Peru, which was formed and presented by the late 

 Lord Brabourne. 



Such notes as were made by the collectors are placed in 

 inverted commas " ", and their names in brackets ( ). 



The references to literature, in addition to those to the 

 original description, are restricted, as much as possible, to 

 works and papers dealing with the Andean region, others 

 being referred to only when there has been a change in the 

 nomenclature. 



A list of the localities where specimens were collected by 

 Simons is given below, arranged in chronological order from 

 his diaries. The names of the Provinces have been added 

 where possible in order to assist in locating the exact 

 situation of the places where the collections were made, 

 which are often not to be found in the most recent maps.
