The Mountain Partridge of the coast belt is so nearly 

 like the plumed partridge of the Sierra Nevada in habits 

 and coloring as scarcely to need a separate description. 

 Both are designated as "mountain quail" in the com- 

 mon parlance, and it is about as difficult to obtain a 

 satisfactory view of one as of the other. The plumed 

 partridge is said to measure a trifle less than this species, 

 but in the field the only distinguishing marks are the 

 grayer tone of the back and the bluish nape, all of which 

 makes it difficult to differentiate the species. The 

 Range is possibly the best guide for an amateur in iden- 

 tifying the species.
