This species takes the place of the preceding at higher altitudes, 

 although their ranges slightly overlap, the present form being found 

 over the whole of the country from 5,000 feet to timberline. It is 

 more abundant in the northern portion of the country, since in the 

 southern part its range is invaded by O. veraguensis. I found it on 

 the Volcanoes Turrialba and Irazu, more abundant at above 7,000— 

 8,000 feet, frequenting the bamboo-choked ravines, where it was ex- 

 ceedingly hard to shoot. They have a low whistling call, which is not 

 often heard, and seems to be used principally for calling together the 

 scattered covey, after the manner of our quail.

It is a very unusual occurrence to find two such closely related 

 species occupying the same range as is found in the case of O. guttatus 

 and veraguensis. O. guttatus is the northern form, going as far south
