THE GENUS CHOEDEILES SWAINSON OBBBHOLSEE. 63 



in the United States National Museum. The face of its label is as 

 follows : 



Pacific E. E. S. Near 38° L. Lt. E. G. Beckwith, TJ. S. A. 



6696 Chordeiles henry 



Elo Grande Valley Kreutzfeldt 10 



On the reverse side is the word " type " in Professor Baird's hand- 

 writing. This specimen was really taken in the San Luis Valley near 

 38° north latitude, in central southern Colorado, where Lieutenant 

 Beckwith's expedition is known to have traveled. Professor Baird 

 recorded this specimen as the type of Chordeiles mrffinicmus Jienryi^ 

 but, possibly by typographical error, gave it the wrong number 

 (6690) ;^ and on the following page,^ in the " List of specimens," still 

 another erroneous number (6698) . This example is, however, not the 

 real type of Chordeiles mrginianus henryi, which came from Fort 

 Webster, New Mexico, as we shall fully explain under that form,' 

 and Professor Baird in considering it such was evidently under mis- 

 apprehension regarding the specimen on which Mr. Cassin based his 

 description of ChordeUes henryi.*' This supposed type is a female, 

 in Juvenal plumage, though full grown, with spotted throat and 

 much mottled upper surface, and is undoubtedly an example of the 

 present race, Chordeiles virginiamAis howelli.
