Ibagii^ (alt. 4850 ft.), a city of several thousand people, is situated at the 

 definite junction of the Magdalena Valley plains with the mountains. From 

 this point to the Magdalena River the road passes through a grass-covered, 

 grazing country with more or less scrubby tree growth bordering the streams, 

 but with no real forest. Highly eroded, castellated buttes, arising abruptly 

 several hundred feet from the plain, are characteristic features of this part 

 of the Magdalena Valley and at least as far north and east as the vicinity 

 of La Dorada on the river, where the semiarid upper valley merges into the 

 humid forest region. 



The descent is not noticeable, but at Chicoral on the Coello River and 

 distant some thirty miles from Igabiie, we have dropped to an elevation of 

 only 1800 feet, and Honda, on the river, is but 600 feet above the sea. 



The country lying between Honda and Barranquilla is described under 

 Expedition No. 7. 



Expedition No. 2.— The Popayan Region. May IS, 1911 -July 21, 1911. 



Personnel. — Leo E. Miller; W. B. Richardson. 



Itinerary. — On May 13, 1911, a few hours after Chapman and Fuertes 

 started their homeward journey in reconnaissance over the Quindio Pass, 

 Miller and Richardson with their pack mules left CaU for Popayan. They 

 reached that city on the 17th, and three days were consumed there in making 

 preparations for a trip to the Western Andes. On May 20 they left Popayan 

 for Cerro Munchique, making their first collecting station May 22, at an ele- 

 vation of 8325 feet on this mountain. They remained at this station until 

 June 4, when they left for Cocal on the western slope reaching that place 

 June 6, and working there until June 18 when they returned to Popayan 

 for supplies'. June 24 they again left Popayan for the Western Andes 

 working at Gallera from June 26 to July 4; La Florida July 5 to 9, and on 

 the summit of the first ridge of the Western Andes (10,340 ft.) from July 

 10 to 23. At this point they found a typical Temperate Zone fauna, this 

 being the first time this fauna has been discovered in the Western Andes. 

 July 27 they returned to Popayan and at once left for their base at Call. 



Description of Route and Collecting Stations.^— "The country " through 

 which we passed on the road to Jamundi is level, covered with excellent 

 grass and given up largely to cattle ranches. Two hours beyond Jamundi 

 the country became rolling and here the lomas, or hill country, begins. 

 At 2 P. M., May 14, we crossed the Cauca, here practically as wide as at
