1872, his chief criticism being that certain species known to him as 

 occurring in Kansas were not included, and that five species were 

 erroneously indicated as breeding in Kansas. 



In the American Naturalist for August, 1872, Dr. T. M. Brewer 

 expressed his obligations to the author of the list for not having in- 

 cluded therein any " birds in regard to whose occurrence in the state he 

 he had not positive evidence, and who had been able to resist the be- 

 setting temptation to swell his catalogue by mere guesswork, or by 

 giving a redundant list of birds that 'probably would be' or 'ought to 

 be found' within the prescribed limits." In the same number of the 

 American Naturalist I published a list of forty-five additional siDecies, 

 of which number Mr. Allen contributed twenty-one species (all of 

 which have been retained). Prof. S. F. Baird, the secretary of the 

 Smithsonian Institution, twenty-three species,* and Mr. E. A. Pope- 

 noe, of Topeka (then a student of Washburn College), one species 

 ( Coturni cuius henslowi ) . 



In the meantime, in the June, 1872, number of the Kansas Edu- 

 cational Journal, I had published forty of the above-mentioned 

 forty-five additions, and in Weston's Guide to the Kansas Pacific 

 Railway, which appeared in July, 1872, a pamphlet of 204 pages, I 

 had published an amended Catalogue of the Birds of Kansas, con- 

 taining 277 species and varieties. No "separates" of this catalogue 

 were obtained. This was in reality my second edition. 



In October, 1872, I issued a third edition, commonly known as the 

 "second edition," and containing 282 species and varieties. 



In 1875 I contributed to the Kansas Academy of Science a third 

 (in reality the fourth) edition, which was published in separate form, 

 and was complete to January 1, 1876. It enumerated 302 species and 

 varieties (295 species and 7 varieties), of which 137 were marked as 

 breeding in Kansas. It omitted four species of the second edition, 

 viz.: Contopus richardsonii, Empidonax pusillus, Passerculus 

 alaudinus, and Sterna hirundo. The latter species was omitted from 

 the fear of its having been confused with Sterna forsteri; Contopus 

 richardsonii and Empidonax pusillus were omitted from fear of in- 

 correct determination ; and Passerculus alaudinus was omitted, not 

 from any doubt of its occurrence in Kansas, but because Doctor Coues, 



*The twenty-three species contributed by Professor Baird were as follows: Hypotrior- 

 chis richardsonii, Ictinia mississippienis, Milvulus forficatus, Tardus pallasii, Helmin- 

 thophila chrysoptera, Seiurus noveboracensis, Dendroica ceerulescens, Dendroica vireas, 

 Piranga wstiva, Vireo noveboracensis, Vireo solitarius, Troglodytes hyemaiis, Sitta cana- 

 densis, Plectrophanes pictus, Plectrophanes raelanomus, iEgialitis meloda, Squatarola 

 helvetica, Actodramus bairdii, Limosa hudsonica, Numenius hudsonicus, Gallinula galeata, 

 Bernicla hutchinsii, and Merganser serrator. All of these additions of Professor Baird have 

 been confirmed by subsequent captures, except the six following: Helmiuthophila 

 chrysoptera, Dendroica virens, ^gialitis meloda, Charadrius squatarola, Numenius hud- 

 sonicus, and Merganser serrator.
