This Junco is distinguished at a glance from thurberi, which 

 it appears to approach nearest, by the decided slate-gray aspect 

 of the fore breast, jugulum, and throat. The palest female thur- 

 beri I have seen is distinctly darker than the darkest male pino- 

 sus of the series. The average greater length and breadth of the 

 bill is also a prominent character when the two birds are com- 

 pared The color of the bill and the color of the eyes were not 

 noted in the field, which is to be regretted, as additional charac- 

 ters might have been afforded by their determination. 



I have described this new Junco provisionally as a distinct 

 species, because the material within my reach has not shown that 

 it intergrades with thurberi or any other form. The name chosen, 

 pinostis, is from Point Pinos, the place of discovery, which forms 

 the south side of the entrance of Monterey Bay. I first met with 

 it in a pine grove on the reservation of the Point Pinos Light- 

 house, June 21. 1892, my first collecting day in the locality. 

 Subsequently I found it was a common bird, frequenting the 

 more open places in the pine woods which largely cover the high, 

 cold promontoiT of Monterey. 



The fact that a Junco should be found breeding at the sea level 

 so far south in California is very significant and in itself is enough 

 to suggest the existence at least of a local race. It will be inter- 

 esting to learn the status of the birds breeding in the Coast Range, 

 particularly those of Santa Clara County. 



Since the above was penned I have submitted the specimens 

 described to Mr. Ridgway and he writes me : "I have examined 

 them carefully, and have not the slightest difficulty in recogniz- 

 ing the marked differences presented by your birds from a series 

 of y. h. thurberi. There can be no question as to their distinct- 

 ness."
