than that at Juntas de Tamand and not very different from that at Rio Frio. 

 The clearing in which the town lies is of much greater extent than at Juntas 

 de Tamana, and as a result more of the open country birds such as the little 

 Black and White Finches, Blue Tanagers, etc. were found. In the forest 

 birds were most abundant about small clearings or plantain patches which 

 filled these small clearings, especially about flowering trees. 



"We left Novita in a canoe hoping to make good connections with the 

 steamer at Noanama which however did not appear. Fortunately Mr. 

 D. C. Stapleton was passing up the river in his launch which was to return 

 in a few days, and he offered to ship us back to Buenaventura, an invi- 

 tation we gladly accepted. 



"The country seems about the same along the San Juan until one gets 

 to sea-level where there is a great increase in the number of species of palms, 

 and from the little we could see from the launch, the forest appears much 

 denser and more luxuriant.'' 



Expedition No. 4- — CaH to San Agustin. February 27 -April 7, 1912. 



Personnel. — L. E. Miller and A. A. Allen. 



Itinerary. — Proceeding to Popayan over the route followed by Miller 

 and Richardson in May, 1911 (See Expedition No. 2), Miller and Allen, 

 accompanied by J. T. Lloyd, left Popayan on foot February 27, 1912, and 

 traveled southward to La Sierra (Feb. 29-March 4) and Almaguer (March 

 9-18). At the last-named point they turned to the east to cross to the 

 Magdalena Valley, stopping at Valle de las Pappas (March 22- April 4), 

 and reached San Agustin April 7, after a difficult and trying journey. 

 Allen suffered much from a recurrence of fever acquired in the Choco and 

 shortly after arriving at San Agustin his condition became so serious that he 

 was obliged to go to Bogotd for treatment and subsequently was invalided 

 home. 



Description of Eaute and Collecting Stations. — • The following notes are 

 supplied by Dr. Allen: 



Popayan to San Agustin. — " Leaving Popayan (Feb. 27) the country 

 continues very similar to that to the north of the city ranging, from 4700 

 to 6800 feet in altitude and sparsely covered with vegetation except in the 

 immediate vicinity of the rivers. (The haze or the fog was always so dense 

 that observations of distant ranges or peaks was impossible so that the 

 notes must of necessity be restricted to the country in the immediate vicin- 

 ity of the trail). 



"The fauna and flora likewise continues practically the same, being 

 similar to that of the open country just below El Roble which •! have called
