Todd-Carriker : Birds of Santa Marta Region, Colombia. 107 



Aside from the coast, the region has never been adequately surveyed, 

 and much of the detail shown on the maps of Simons (1881) and 

 . Sievers (1888) is conjectural. The courses of the streams as indi- 

 cated by the former authority are often exceedingly inaccurate, as 

 both Mr. Smith and the junior author unite in testifying. In the 

 map which we present herewith an effort has been made to correct 

 some of the worst of the errors into which previous authors have 

 fallen, but it must be acknowledged that the final result is still far from 

 satisfactory, and must be regarded at best as scarcely more than 

 semi-diagrammatic. For many of the localities specified on the fol- 

 lowing list, therefore, the indicated position is only approximate, and 

 due allowance must be made for such discrepancies as exist. 



The list includes the names of all places, streams, swamps, and. 

 mountains mentioned in the text as situated in the Santa Marta region, 

 with a reference to their location and a brief description of their phys- 

 ical features, faunal position, etc. This detailed information is in- 

 tended to supplement the general account of the geography and physi- 

 ography of the region as a whole, and should, be consulted in connec- 

 tion therewith. The altitudes are quoted sometimes from one author- 

 ity, sometimes from another, with the result that there is no uniformity 

 in this respect. In fact, scarcely any two of the authorities agree in 

 this matter-^a circumstance which need excite no remark, since vir- 

 tually all the figures given are based on the indications afforded by 

 aneroid barometers, the inaccuracy and variability of which are well 

 understood. While there are thus unavoidable inconsistencies and 

 inaccuracies in details of this nature, it is hoped that they are not 

 of such a kind or degree as seriously to affect the general value of 

 this paper or to impugn the scientific conclusions at which we have 

 arrived. 



Aduriameina. — A point on the southern spur of the Sierra Nevada, 

 on the trail leading up to the Snow Peaks, where there is a hut built 

 for shelter, in the midst of " lovely green pastures." Simons refers 

 to this locality in describing his ascent of the Sierra Nevada; its alti- 

 tude (according to Sievers) is 3,370 meters (11,050 feet). 



Agtia Dulce.—A plantation in the western foothills of the San 

 Lorenzo, less than two miles south of Minca, on the road to the 

 hacienda Cincinnati, and lying at an altitude of from 2,500 to 3,000 

 feet, in the upper Tropical Zone. It is very broken, country, orig-
