CATALOGUE OF CANADIAN BIRDS. 369 
MUSEUM SPECIMEN. 
__ One young specimen, taken at Kamloops, B.C., June 24th, 1889, 
by Mr. Spreadborough. 
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 Zhe 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 to make my own 
work clearer.
