at the hacienda of Senor don Ricardo Jimenez, on the Volcano de 

 Irazu, collecting chiefly between the altitudes of 8,000 and 10,000 

 feet. The last two weeks of March were spent at Juan Vinas, where 

 the collecting was all done in the vicinity of the railway station and 

 down in the gorge of the Rio Reventazon. 



On the first of May I started with Mr. C. F. Underwood on a trip 

 to Pozo Azul de Pirris, lasting two and a half months, after the con- 

 clusion of which I returned to the United States. All the birds col- 

 lected on this trip were sent to the Carnegie Museum. 



In the spring of 1903 I returned to that country, accompanied by 

 Mr. J. C. Crawford, now Assistant to Dr. Howard, Chief of the 

 Division of Entomology of the United States Departure of Agriculture. 

 We collected during the latter part of February and the whole of March 

 around Guapiles, at the terminus of the Old Line Railway. In April, 

 after collecting a few days at Guacimo, we penetrated into the foot- 

 hills at the northern base of the Volcan de Turrialba, spending two 

 weeks at a point about 2,000 feet above sea-level in the heart of the 

 virgin jungle. The illness of Mr. Crawford prevented a longer stay 

 at this point, which has an exceedingly rich bird-fauna, and soon after 

 Mr. Crawford was compelled to return to the United States on account 

 of his health. 



I did no more collecting until November of that year, when I worked 

 at Guacimo up to the middle of January, 1904, going thence to 

 Talamanca, where one year was spent in intermittent collecting. All 

 my collecting in that region was done along the Sicsola River, between 

 Cuabre and the mouth of that stream. I returned to the Old Line in 

 1905 and spent from August 10 to September 17 at Carrillo and from 

 September 18 to October 10 at La Hondura, getting splendid series 

 of specimens from both localities. From that time on until March, 

 1907, I was stationed more or less permanently at El Hogar, eight 

 miles east of Guapiles, and during the time spent there was able to 

 collect a great many rare species as opportunity offered. 



However, I was able to spend the time from April 24 to July 1, 

 1906, in Guanacaste in company with Mr. C. H. Lankester, during 

 which time we collected extensively at Bebedero, Bagaces, and Mira- 

 valles, besides securing a few specimens at other points. I am greatly 

 indebted to Mr. Lankester for his assistance to me on this trip, and it 

 is owing to his endeavors that many of the rarer species were secured. 



Early in April, 1907, I left El Hogar, going to Juan Vinas, where
