satisfactorily known. Miller and Allen in their rapid crossing from Cartago 

 to Novita took species not found by us elsewhere, while work in Tatamd. 

 Mountain and Cerro Torra in this region, the 'Paramo' of Frontino to 

 the north, and Farallones of Call to the south, would be certain to yield 

 valuable results. 



The Patia Valley with its unique tropical connection with the Pacific 

 coast, offers an unusual problem in zoogeography, while the Pacific coast 

 itself is ornithologically unknown from the Patia to the San Juan rivers. 

 Particularly, would I call attention to the need of further exploration in the 

 Choco region, and especially in the Baudo range and mountains on the 

 Panama frontier. 



Expedition No. 1. Buenaventura to the Cauca Valley; Reconnaissance, Cali 

 to Giradot over the Quindio Pass. November 10, 1910- June 4, 1911. 



Personnel. — Frank M. Chapman, Louis A. Fuertes, Wm. B. Rich- 

 ardson, Leo E. Miller. 



Itinerary. — Richardson reached Buenaventura on the Pacific -coast, 

 alone, on November 9, and proceeded at once to Caldas (alt. 2560 ft.) 

 distant forty miles at the end of the railway under construction from Buena- 

 ventura to Cali. He remained at Caldas until November 24, and thence 

 retraced his steps some fifteen miles to San Jose (alt. 600 ft.) collecting there 

 from November 27 to December 18. On the last-named date he left for 

 CaU, at the eastern foot of the Western Andes, and this large, attractive 

 city became our base of operations for the succeeding year. Collections 

 were made about Cali until December 31, when Richardson moved to.the 

 mouth of the pass (alt. 6600 ft.) in the Western Andes, 3100 feet above the 

 town, and established himseH at a wayside posada surrounded by forest. 

 This locality is known as Las Cruces, from three large crosses which mark 

 the divide,,and also as San Antonio, from a small settlement just below the 

 pass on the trail to Cali. It was at this point that Mervyn G. Palmer 

 made part of the important collections purchased by Mr. Bangs; and at 

 El Tigre, a ranch about 1500 feet below the divide and to the west, Eugene 

 Andre collected. 



February 26, Richardson moved from San Antonio to Las Lomitas 

 (alt. about 5000 ft.), a ranch on the Pacific slope some five miles to the 

 northwest, and worked there until March 7. 



In order to be near the coast while awaiting the arrival of the remainder 

 of the expedition, Richardson went to Los Cisneros (alt. 900 ft), also known 

 as Juntas, at the junction of the Dagua and Las Petitas rivers, and the head
