SEPT.. 1910. BIRDS FROM COSTA RICA FERRY. 259 



utilized for collecting, on January 14 at Turrialba Station and on 

 March 9 at Port Limon. 



Acknowledgments are gratefully made to the United Fruit Com- 

 pany, who gave me much advice and kindly treatment, including the 

 placing at my disposal of a part of their shipping-room. Here, with 

 excellent facilities and materials for packing, I was able to prepare 

 my specimens for shipment with great success. Mention should also 

 be made of a provision made for me by Mr. Musgrove, Superintendent 

 of the Electric Lighting Plant of Port Limon. In a warm, dry place 

 near the boilers I was allowed to dry perfectly several hundred skins. 

 The humid conditions at the coast made the drying of these skins im- 

 possible without the aid of artificial heat. 



I also gratefully acknowledge courtesies extended to me by the 

 Northern Railway of Costa Rica. They placed at my disposal trans- 

 portation facilities which allowed me the fullest possible use of their 

 lines. Mr. Donaldson, the United States Consul at Port Limon, has 

 also my grateful appreciation for services rendered. 



Finally, I wish to thank Mr. Ridgway and others at the National 

 Museum, \\ ho kindly assisted me in the identification of several puz- 

 zling species.

This specimen is referred to the above form recently described by 

 Bangs, as it occurs within the range allotted to the new species, in 

 fact not far from Cartago, the type locality. The bird was perched 

 at the edge of a small clearing in a dense forest and allowed a close 

 approach. The stomach contained hair of a small mammal.
