biers now before me, ii show the chestnut stripe on the sides; in 6 of 

 these, however, it is onlv faintly indicated. One of the 40 has the yellow 

 crown of the adult; all have the wing-bands strongly tinged with sulphur 

 yellow, and almost all are bright olive green above. 



The first arrival for the fall of 1890 was September 21. 



16. Dendroica zestiva. — L have before me 33 males and 15 female Yel- 

 low Warblers, including specimens from both the Atlantic and Pacific 

 sides of the country, but the majority are from the vicinity of San Jos6. 

 I believe all are true cEstiva, although the difterence between birds from 

 the extremes of the series is very great. Eight of the 32 males have the 

 chest and sides more or less streaked with chestnut. From a bird thickly 

 marked with rather broad reddish chestnut streaks there is a gradual 

 variation, the streaks becoming fewer, narrower, and lighter until just 

 discernible. The yellow of the under parts also grows appreciably 

 paler: only 4 of the iS show faint chestnut streaking on the back. Above 

 yellowish olive green ; some of those that are brighter colored below have 

 the crown more oi- less ochraceous orange, but this color gradually darkens 

 into the yellowish olive green of the back. In the remaining 14 males, 

 those in which the chestnut streaks are almost entirely obsolete, the yellow 

 of the underparts grows fainter and varies from gamboge yellow to clear 

 straw yellow. Above there is no sign of streaks and the yellowish color 

 gradually disappears giving place to dusky graj'ish. until the last which 

 I would describe as dusky grayish olive green. 



The 15 female examples show the same variations as noted in the 

 males, only the brightest female is not as bright as the brightest male, 

 and at the other end of the series they are duller above and somewhat 

 paler below. 



The first arrivals the present year were noted August 24.

My experience on the coast of New England has shown that 

 observations covering a .series of years are necessary in order to 

 arrive at anv important conclusions respecting the habits and 

 movements of the water birds during their passage along tliis
