82 BATCHELDER—TWO NEWFOUNDLAND Birps.  [P-4:F-2.0- 
Dendroica aestiva amnicola subsp. nov. 
Type, from Curslet, Newfoundland, @ adult, no. 5360, coll. of C. F. 
Batchelder, collected June 14, 1890, by J. C. Cahoon. 
Characters. — As compared with Dendroica aestiva aestiva, the adult male, 
in breeding plumage, has the back, from crown to upper tail coverts, in- 
cluding scapulars, conspicuously darker green, less yellowish, — between 
‘warbler green ’ and ‘ sulphine yellow ’; the yellow of the forehead is more 
restricted and duller, — in color between ‘ apricot yellow’ and ‘ primuline 
yellow ’; the yellow edges of remiges are narrower, and duller in color, being 
dull ‘ citron yellow’ as contrasted with the ‘ strontian yellow’ of aestiva. 
When seen in series, the yellow of the under parts is duller, less richly golden, 
and the chestnut streaks are darker. In comparison with aestiva, the female 
is duskier, less yellowish, throughout the upper parts. 
Measurements. — Average of fourteen adult males: wing, 61.2; tail, 
42.6; culmen, 11.6; tarsus, 19.4 mm. Average of three adult females: 
wing, 58.0; tail, 42.7; culmen, 11.0; tarsus, 18.7 mf. Ten other birds 
examined were not measured, because they were taken in the moulting 
Season or were immature. 
Remarks. — In general coloring D. ae. amnicola shows a cer- 
tain similarity to D. ae. rubiginosa, but it is readily distinguish- 
able from that race by the yellow forehead which, as in D. ae. 
aestiva, contrasts strongly with the green of the back. With the 
other subspecies of western North America this dark bird needs 
no comparison.
