Approximately 200 of the most interesting specimens were preserved as study skins and are in the University of Kansas Museum of Natural History. An effort was made to preserve at least one of each species, and we fell only a few short of this goal. All of the forms rare in Kansas are represented by skins. We could see no reason to list the preserved specimens in detail here. Species of which no study skins were made, however, are so marked. So far as we can tell, no truly western subspecies (from west of the Great Plains) occurred in the Topeka sample. Probably most or all of the birds came from areas more or less directly north of eastern Kansas. In critical areas where different subspecies of the same species occur together in migration, data from samples of this kind should prove enlightening. In future analyses, conducted in such areas, it might be possible to preserve all specimens of some of the variable species, or at least to measure all individuals of species in which size is the most important variable character. Quantitative study could then be made of the different geographic variants occurring, their proportions in the migrant population determined, and their origins deduced. In studying populations of Painted Buntings (_Passerina ciris_) wintering in Mexico, Storer (1951) has provided an interesting demonstration of methods which can be applied to such samples. A few bats killed at the tower provided a surprise. They will be discussed separately by Richard Van Gelder. _Podilymbus p. podiceps._ Pied-billed Grebe.--Weights: male, 394.8 (all weights in grams); females, 332.5, 289.7; all fat. _Butorides v. virescens._ Green Heron.--Weight: 1 (unsexed), 168.6. _Anas discors._ Blue-winged Teal.--Weights: 4 males, mean 421.2 (391.3-458.1); 3 females, 367.7, 371.6, 393.2; all fat. _Rallus limicola._ Virginia Rail.--Weights: 3 males, 73.7, 83.2, 90.5; 1 female, 67.3; moderately fat to fat. _Porzana carolina._ Sora.--Weights: 4 males, mean 76.8 (68.7-89.9); 3 females, 62.6, 63.2, 63.5; moderately fat to very fat. _Fulica americana._ American Coot.--Weights: 2 females, 385.3, 530.0, both fat. None preserved. _Zenaidura macroura marginella._ Mourning Dove.--Weights: 2 adult males, 121.8, 140.2; 3 immature males, 113.1, 126.1, 130.0; 3 adult females, 122.5, 126.9, 136.0; 2 immature females, 129.4, 132.7; moderately fat to very fat. The presence of Mourning Doves in the sample is interesting as these birds are not generally regarded as night migrants. Conceivably the specimens were local birds going to roost. None preserved. _Colaptes auratus luteus._ Yellow-shafted Flicker.--Weights: 2 males, 126.0, 139.4, little fat. Flickers have several times been recorded as night migrants.
