own winter records, while covering 5 successive years, are 
enly 17 in number. Mr. Brown’s are even less. 
On the other hand, there is a distinct migration arrival in 
the spring, with a less distinct one in the fall. Thus the 
sudden appearance of about 400 of these near my home on 
March 17, 1918, where not a single individual of the species 
had been seen within a radius of a mile and a half during 
winter, and only 43 in a radius of some 5 miles, looks de- 
cidedly like migration. In this connection, reference may be 
made to the migration records given in Table I. ; 
137.  Spinus pinus pinus (Wils.) Pine Siskin. A rather 
“uncommon irregular winter visitant. Arrives in early No- 
vember; time of departure not determined. 
138. Plectrophenax nivalis (Linn.) Snow Bunting. An 
irregular winter visitant. Typical records are: March 12, 
1916, Wildwood Park, 1 individual, with Goldfinches; No- 
vember 3, flock of 21, St. Charles St., Charles City; March 1, 
1917, small flock, north of Charles City. (H. Newton.) 
139. Calcarius lapponicus lapponicus (Linn.) Lapland 
Longspur. An irregular and uncommon winter visitant, 
arriving in November. Large flocks are seldom seen. 
140. Calcarius ornatus (Towns.) Chestnut-collared Long- 
spur. My only reliable record for this species is a specimen 
from the Miles collection, identified by Dr. Bailey. The speci- 
men was taken at Charles City; no date given. 
141. Poocdetes gramineus gramineus (Gmel.) Vesper 
Sparrow. An abundant migrant and common summer resi- 
dent. The first arrivals appear in late March, and the species 
is most abundant about April 15. Departure takes place in 
early October. Nesting takes place in June. 
142. Passerherculus sandwichensis savanna (Wils.) Sa- 
vanna Sparrow. A common migrant, arriving in early April 
and becoming common in the middle of that month. I have 
one record, made by Howard Clarke Brown and myself for 
March 12, (1916.) Some 12 individuals were seen in Wild- 
wood Park. One individual was seen in the vicinity of Willow 
Pond on July 13, 1917. There are no records of nests having 
been found. 
143. Ammodramus savannarum austalis Mayn. Grass-
