 through Mr. Gerrit S. Miller. 



The route followed by the expedition was the so-called ' ' Moyobamba 

 route," over which no zoologist had traveled previously, although the 

 Polish naturalist Stolzmann had covered some parts of it about thirty 

 years before. A preliminary trip was made during March into the 

 mountains east of Trujillo in the vicinity of Otuzco after which the 

 main journey was begun. We left the coast at Pacasmayo going by 

 rail across the arid plain and thence proceeding with mules over the 

 mountains by way of Cajamarca, Balsas, and Chachapoyas to Moyo- 

 bamba. Thence to Balsapuerto we went on foot over a rough trail 

 with Indian porters or cargueros carrying our collections and equipment. 

 The remainder of the journey was by water, from Balsapuerto to Yuri- 

 maguas by canoe on the Paranapura River and from Yurimaguas down 

 the Amazon by steamship. 



The localities at which collections were made are as follows: 



Menocucho, Feb. 2i-Mch. 5. A small village at the terminus of a 

 short railway line running eastward from Trujillo a distance of about 

 20 miles. The region is mostly arid and forbidding but along the banks 

 of a small stream, the Moche River, there is considerable light growth 

 of thorny bushes and small trees while near by are canefields and small 

 gardens under irrigation. Altitude 900 ft. =>= l 



Hacienda Llagueda, Mch. 8-Mch. ij. A large hacienda near the 

 headwaters of the southern branch of the Chicama River, owned by 

 Sr. Armas of Trujillo to whom, as well as to his eldest son Don Luis 

 Armas, we were indebted for many favors. This place was reached by 

 trail from Menocucho to Otuzco and thence across the divide separating 

 Otuzco from the drainage of the Chicama. The hacienda occupies 

 both sides of a very steep canyon traversed by a small swift stream. 

 Although there is some open country, uncultivated vegetation is rela- 

 tively profuse largely on account of fogs which constantly settle in the 

 canyon. The cultivated crops are principally coffee and coca. Altitude 

 6,000 ft. 



Mountains near Otuzco, Mch. 19-20. The locality to which this 

 phrase refers is near the top of the divide between Otuzco and the 

 Chicama drainage but on the Chicama side overlooking the canyon of 

 Llagueda. Altitude 10,000 ft. ="= 



Trujillo, Mch. 25-26. Small collections made here are from thickets 



1 Altitudes are given on local authority or upon the basis of estimates, since it 

 was our misfortune to lose our aneroid at the very outset.
