continental divide (elevation 300 feet above sea-level) the valley of the Atrato 

 was entered near Tambo. By dugout to the settlement of Boca de Raspadura; 

 thence the Raspadura River was followed into the Quito River, then the Quito 

 River. Collections were made at Boca de Certegui and near the town of Quibdo, 

 at the junction of the Quito River with the Atrato. From Quibdo, a steamer 

 was taken to Rio Sucio, where additional collections were made. From Sucio, 

 a steamer carried the Expedition back to the starting point at Cartagena. 



These collections have been supplemented since my return by material 

 collected by Manuel Gonzales, near Puerto Wilches, at Las Juntas on the Rio 

 Bogota, in the province of Santander, and along the way from Bogota to Villa- 

 vicencio. The first series of the specimens and the duplicates are in the Carnegie 

 Museum, the second series in Indiana University. 



The Landon-Fisher Expedition to Colombia. 



A second Expedition into Colombia was made possible by Mr. Hugh McK. 

 Landon and Mr. Carl G. Fisher, of Indianapolis. 



Mr. Arthur W. Henn and Mr. Charles Wilson, undergraduates in Indiana 

 University, left in December, 1912. They landed at Tumaco, near the south- 

 western corner of Colombia. After devoting about a month's time to the 

 Telembi River, a tributary of the Patia, they separated. Mr. Wilson went to 

 the San Juan River, collecting in the Upper San Juan Basin, the Condoto River 

 at Condoto, and in the San Juan River at Istmina and Tado of the Pacific side, 

 and later on the Atlantic slope at Tambo, Raspadura, Boco de Raspadura, 

 Managru, Quibdo, in the Atrato between Quibdo and Rio Sucio, and especially 

 in the Truando River emptying into the Atrato near Rio Sucio. 



The Landon Expedition to Colombia and Ecuador. 



Through the continued liberality of Mr. Hugh McK. Landon of Indianapolis, 

 Arthur W. Henn was able to remain in South America and spend the time between 

 February 15, 1913 and March, 1914 in collecting fresh-water fishes in Colombia 

 and Ecuador. 



He sailed from Tumaco, Colombia for Barbacoas on February 15th. From

 Los Llanos de Sandona (5000 feet), Tambo, Pefiol, and to Guayabillo on the
