At about the same time that Mr. Cherrie went to Costa Rica (1890) 

 Mr. C. F. Underwood also arrived there, having been induced to go 

 through the efforts of Senor Zeledon, and he has been collecting birds, 

 mammals, etc., more or less continuously since that time. Enormous 

 quantities of birds were sent to England and other parts of Europe, 

 his skins being found in nearly every collection of importance in 

 Europe. Very few ever found their way to this country until 1907, 

 when Mr. Bangs received a large collection from the Terraba Valley, 

 from which eight new species and subspecies were described. The 

 same year Mr. Bangs secured Underwood's entire old collection of 

 birds, which he had been building up for many years, which contained 

 most of the rare species found in that country, and many specimens 

 which had been identified personally by Salvin. It is of the greatest 

 benefit to American ornithologists to have this magnificent collection 

 of Costa Rican birds in the United States. 



Mr. Underwood collected again in the upper Terraba Valley the 

 following year and in various parts of northwestern Costa Rica, visit- 

 ing Bolson, Coralillo, Tenorio, Cerro de Santa Maria, and La Vijagua, 

 the specimens from all of these localities going to Mr. Bangs. In 1899 

 Mr. Underwood published (under the Museo Nacional de Costa Rica) 

 a list of the birds of Costa Rica, which contains 696 species. There 

 are some synonyms, some species erroneously included, and some 

 errors in nomenclature, but on the whole it is a very complete list and 

 a useful guide to the collector in that country. It cannot be quoted, 

 for the reason that it is a bare list with no authority for the species 

 included, no specimens being cited or authors named. Mr. Under- 

 wood was connected for some years with the Museo Nacional as a 

 collector and taxidermist, many of the birds and mammals now on 

 exhibition in that museum having been mounted by him. In 1896 

 Mr. Underwood published in the Ibis a list of the birds taken on the 

 slopes of the Volcano de Miravalles and in Guanacaste, with notes on 

 habits, abundance, etc., which is of considerable value. 



During this same period (1890 to 1896) numerous papers appeared 

 in the Proceedings of the United States National Museum by Mr. 

 Ridgway and Senor Zeledon on the birds of Costa Rica, in which 

 quite a number of new species were described and much additional 

 information on distribution, nomenclature, and the status of species 

 was given.
