ently a week in September, 1898, covers the whole time spent 

 by Mr. Smith's collectors on or near the seashore at Cienaga. 



While to Mr. Smith is due the credit of organizing and equip- 

 ping the Expedition and directing its work, he has personally 

 done very little of the actual work of bird collecting, which has 

 been carried on by Mrs. Smith, so well known for her previous 

 work on similar expeditions in Southern Brazil, Mexico, and the 

 lesser Antilles, and who, with Mr. G. H. Hull, appears to have 

 secured and prepared the principal part of the collection of birds. 

 Their further work in the Santa Marta region, if they are not 

 driven out by the disturbed condition of the country, will prob- 

 ably add many more species to the list of Santa Marta birds. 



In respect to the faunal relationships of the Santa Marta region, 

 it may be said that while many wide-ranging species common to a 

 large part of tropical America are found here, many of them are 

 represented by geographical forms peculiar to this region, while 

 in the higher parts of the Sierra Nevada occur many distinct 

 species quite unlike their nearest congeners found elsewhere, and 

 belonging for the most part to genera not found in the adjoining 

 low coast region, but which occur in the Cordillera regions of 

 other parts of northern South America. Also it may be noted 

 that many of the species of the list which are abundant at 

 the lower levels, are not recorded from points above 5000 to 

 6000 feet. 



It is further evident that the avifauna of the Bogota region is 

 very different from that of the Santa Marta district, and that also 

 the home of many * Colombia ' species is to be looked for else- 

 where than in eastern Colombia. Indeed, a very different set of 

 birds was met with by Wyatt * in " the eastern Cordillera of the 

 State of Santander," in the Bucaramanga district, midway between 

 Santa Marta and Bogota. 



Unfortunately no field notes are as yet available for publica- 

 tion, but the number of specimens taken of the different species, 

 as here recorded, doubtless indicates to some extent the relative 

 abundance of the species ; while the dates, especially for North 

 American migrants, indicate the season of occurrence. 



I am indebted to Mr. Bangs for sending me for examination
