Date of this Version
The author has published in the proceedings of the Nebraska State Board of Agriculture a complete catalogue of Nebraska serpents including notes and descriptions of the adults and young. Since the preparation of this catalogue Prof. Cope's review of North American snakes has appeared. This together with the fact that the author has had time to review his own studies and add many other notes is sufficient excuse for offering the present catalogue.
In the classification we have followed Prof. Cope. The notes given are confined to the Ophidia or serpents of Nebraska. The range of the collection, which was quite a large one, included the whole State, and only specimens actually examined by the author are included. Typical specimens have been preserved.
