288 Catalogue of Birds from New Grenada. 



XXYIII. — Catalogue of a Collection of Birds ^ made in New 

 Grenada^ ly James McLeannan^ Esq., of New YorJc, with 

 Notes and Descriptions of New Species. Part I. 



By George N. Lawrence. 



Kead January 28, 1861. 



The birds comprised in this catalogue were collected by 

 James McLeaiinan, Esq., on the Atlantic side of the Isthmus of 

 Panama, along the line of the Panama Pailroad, from near 

 the coast to about a central point between the two oceans. He 

 procured only such birds as he had the opportunity to preserve 

 when not otherwise engaged, and had no intention of making 

 a complete collection, many kinds being seen by him which 

 were not obtained. This is to be regretted, as among those sent 

 are many species of much interest. 



Mr. McL. took no notes, as the birds w^ere obtained solely for 

 his own gratification, and with no expectation that a list of 

 them wouW ever be published. He states that the Falconidse 

 are exceedingly numerous and unsuspicious, frequently perch- 

 ing on the telegraph poles, and allowing an approach imme- 

 diately under them without taking alarm.
