boni, from Fort Bridger, Utah, measured,^ as reduced to milli- 

 meters : wing io6, tail 91. And all the southern Rocky Moun- 

 tain examples I have access to have the wing longer than 100 in 

 the male. It is of especial value in the determination of the west- 

 ern races of the Hermit Thrush, that there seems to be but little 

 individual variation in the measurements of a series from a single 

 locality. For instance, the extremes among the 9 females of I'ere- 

 cuiida from Sitka are : wing, 82 to 85 ; tail, 68 to 72. 



Probably most of the summer records of auduboni from the in- 

 terior' of California refer to sequoietisis, while the winter records in 

 some cases seem to be based on large males of the olivaceous 

 aonalasc/ikce, which winters abundantly in the interior and southern 

 portions of the State. The bright brown-backed, buffy-breasted 

 verecunda, as shown by many specimens examined, passes the 

 winter principally in the cloudy coast belt. It is the prevailing 

 form in winter in the San Francisco Bay region and Santa Cruz 

 Mountain district. Both sequoiensis and slevini evidently winter 

 entirely south of California. 



At the suggestion of Mr. L. M. Loomis, the subspecies herein 

 described is named for Mr. T. E. Slevin of San Francisco, a quiet 

 but ardent bird-student. 



THE WINTER BIRDS OF PEA ISLAND, NORTH 

 CAROLINA. 



BY LOUIS B. BISHOP, M. D. 



Bleak and dreary seemed Pea Island — a monotonous sand-flat 

 with promontories of marsh-grass, its dull level broken only by a 

 few scattered buildings and here and there a low sand hillock — 

 as I watched it on the afternoon of February 7, 1901, from a small 

 boat which two colored boatmen had succeeded in getting hard 

 aground on the flats that stretched for miles into Pamlico Sound.
