_Dendroica magnolia._ Magnolia Warbler.--Weights: 1 adult female, 9.0, moderately fat; 2 immature females, 7.9, 10.3, moderately fat and fat. _Dendroica c. caerulescens._ Black-throated Blue Warbler.--Weights: 2 immature males, 13.8, 14.1, excessively fat; 1 immature female, 11.4, fat. This species is rare in Kansas. Although its breeding range is almost entirely east and north of Kansas, records in files at the University of Kansas show that more specimens have been taken in western than in eastern Kansas. _Dendroica c. coronata._ Myrtle Warbler.--Weight: 1 immature female, 11.6, fat. _Dendroica pensylvanica._ Chestnut-sided Warbler.--Weights: 2 immature females, 8.1, 10.0, little fat. Only one specimen from Kansas had been preserved previously although the species is a regular transient in small numbers throughout the state. _Dendroica castanea._ Bay-breasted Warbler.--Weights: 1 adult male, 19.2, excessively fat; 1 adult female, 11.7, little fat; 1 immature female, 11.2, moderately fat. Only 5 specimens of this warbler have been taken previously in Kansas, 4 in spring (Ruth, 1952:18-19) and 1 in fall. _Dendroica p. palmarum._ Palm Warbler.--Weights: 2 immature males, 9.9, 10.9, moderately fat; 2 unsexed immatures, 9.1, 9.4, moderately fat. This species has been taken in fall in Kansas only once before (KU 26353, taken by Wetmore, at Lawrence, on October 5, 1907), but probably occurs regularly in both spring and fall migration. _Seiurus a. aurocapillus._ Oven-bird.--Weights: 2 adult males, 22.5, 23.8, fat and very fat; 14 immature males, mean 21.89 ± .66, S. D. 2.46, fat to very fat; 8 adult females, mean 21.4 (18.3-25.7), moderately fat to fat; 6 immature females, mean 18.2 (15.6-20.0), moderately fat to fat. _Seiurus noveboracensis notabilis._ Northern Water-thrush.--Weights: 3 immature males, 18.1, 18.6, 22.2, moderately fat to fat; 1 immature female, 22.2, fat. Referring these birds to _notabilis_ is a somewhat arbitrary procedure. They display some intermediacy of characters and probably stem from a population, intermediate between _notabilis_ and _noveboracensis_, occupying much of central North America (cf. McCabe and Miller, 1933).
