MUSEUM SPECIMEN. 



One young specimen, taken at Kamloops, B.C., June 24th, 1889,

NOTE ON GENUS OTOCORIS. 



My notes on this genus were written before I had seen Mr. 

 Oberholser's " Review of the Larks of the genus Otocoris," pub- 

 lished in Vol. XXIV. of the Proceedings of the U. S. National 

 Museum. Our specimens were sent to Mr. Frank Chapman of 

 the American Museum of Natural History, New York for deter- 

 mination. Mr. Chapman followed Dr. Dwight's arrangement as 

 published in Vol. VII. of The Auk, and I have allowed my notes 

 to stand' as originally written. Below, however, I give Mr. Ober- 

 holser's arrangement with a few added notes \o make my own 

 work clearer.
