474 APPENDIX. 



summer homes are still only imperfectly mapped, but nelsoni is sup- 

 posed to breed exclusively in the interior of North America, and 

 subvirgatus to be restricted to the coasts of the Maritime Provinces 

 south of the mouth of the St. Lawrence. 



Subvirgatus is a very common migrant along the entire New 

 England coast wherever there are marshes suited to its tastes. In 

 the neighborhood of Boston it occurs in spring from about May 20 

 to June 8 ; in autumn from September 3 to November 6, but most 

 numerously in October. 



Nelsoni has not as yet been taken in New England in spring, 

 and its apparent rarity at this season along the coast of the Middle 

 States (the mention in the Auk, Vol. X, 1893, p. 85, of a specimen 

 killed at Atlantic City, New Jersey, May 9, 1892, appears to be the 

 sole record) suggests the inference that its northward migration is 

 practically restricted to paths which lie west of the Alleghanies. 

 But on its way southward the bird visits us quite regularly, arriv- 

 ing early in October, and apparently staying only a very short time, 

 for my earliest and latest dates are the 8th and 15th. Like subvir- 

 gatus it frequents chiefly salt or brackish marshes near the coast, 

 and the two forms are often found together, or at least in close prox- 

 imity. Near Boston they occur in about the proportion of one 

 nelsoni to ten subvirgatus, but in Connecticut nelsoni appears to be 

 sometimes the more numerous of the two (of. Sage, Auk, Vol. VHI, 

 1891, p. 115). 



Spizblla beewbei. Brewer's Sparrow. 



A young male in my collection, shot by Mr. William Stone at 

 Watertown, Massachusetts, December 15, 1873, and brought to me 

 only an hour or two after its death, still furnishes the only New 

 England record of this Western species (cf. Brewster, Am. Nat., 

 Vol. VIII, 1874, p. 336). 



Calamospiza MBLAifocoEYS. Lark Bunting. 



An accidental visitor from the West. The only recorded New 

 England specimen was shot at Lynn, Massachusetts, December 5, 

 1877, by Mr. N. Vickary (Allen, BuU. N. O. C, Vol. Ill, 1878, p. 48). 



Peeisoeeus canadensis. Canada Jay. 



Since writing the foot-note on page 278 I have found, in the 

 Essex County Collection of the Peabody Academy, a specimen 

 which was shot by Mr. Lorenzo A. Smith, at Salem, Massachusetts,
