BIOLOGICAL PAPERS. 173 



Family A rtilocaprid.e. Prong-horned Antelopes. 



5. Antilocapra americana Ord. Antelope. 



Faat disappearing. A recent law protects these animals, but the law is 

 ignored by many of the settlers in western Kansas. A few email herds 

 have been reported to me within the last year as occurring in the ex- 

 treme western counties of the state. 



Family Bovid.e. Cattle, Sheep, etc. 



6. Bison bison Linn. 



Extinct, except in private preserves. 



Order Ul.—J?ODEXTIA. Rodents. 

 Family Sciurid.e. Squirrels, Marmots, etc. 



7. Sciurus rufiventer E. Geoflfroy. Western Fox-squirrel. 



Common in the wooded parts of the state. While not protected by law, 

 it does not seem to be decreasing greatly in numbers. Melanistic 

 forms are common. 



8. Sciurus carolinensis Gmel. Gray Squirrel. 



Found in eastern and southeastern Kansas. 



9. Tamias striatus Linn. Chipmunk. 



The chipmunk was reported by Professor Knox, and undoubtedly is rarely 

 found in eastern Kansas. The form may be one of the subspecies re- 

 cently described, probably T. S. griseus Mearns, but until specimens 

 from the state can be obtained for examination the matter will be in 

 doubt. 



10. Citellus spilosoma major Merr. 



Taken by me at Kinsley, in October, IBO-l. Probably common in the sand- 

 hills of the Arkansas valley. 



11. Citellus tridecemlineatus Mitch. Striped Spermophile. 



Common in the eastern half of the state. 



12. Citellus tridecemlineatus pallidus Allen. Pale Striped Spermophile. 



Replaces the last in west Kansas; abundant. 



13. Citellus franklini Sabine. Franklin's Spermophile. 



Found in most parts of the state ; not common. 



14. Cynomys ludovicianus Ord. Prairie-dog. 



Fast disappearing in some sections of western Kansas, but still suflBciently 

 numerous in others. 



15. Marmotta monax Linn, Woodchuck, Groundhog, 



Found in northeastern Kansas; not very common. 



16. Sciuropterus volans Linn. Southern Flying Squirrel. 



Found only in wooded parts of eastern Kansas. Rarely seen because of 

 its nocturnal habits. 



Family Castorid^. Beavers, 



17. Castor canadensis Kuhl. American Beaver. 



Once abundant on our streams; now rare.
