NOTES ON KANSAS MAMMALS. 



By D. E. Lantz, Biological Survey, Washington. D. C. 



\ MONOGRAPH on the hares and rabbits of North America 

 ^-^ has been prepared by Mr. E. W. Nelson, of the United States 

 Biological Survey, and will soon be published. The examination 

 of specimens collected in Kansas shows that two hitherto unre- 

 ported races of rabbits occur there. They are Sylvilagus f>ori- 

 danus similis and Sylvilagus auduboni haileyi. These make the 

 total number of forms of rabbits known from the state seven, as 

 follows : 



Lepus campestris ^dichmd^n. White-tailed Jack- rabbit. Oc- 

 curs throughout the northern half of the state, and in the western 

 part, perhaps south of the Arkansas river. The American Mu- 

 seum, New York, has specimens from Garden City. 



Lepus malanotis (Mearns). Black-eared Jack-rabbit. Oc- 

 curs throughout the state, but is not common in the extreme north- 

 eastern part; abundant in the western part. 



Sylvilagus floridanus mearnsi{A\\Qn). Mearn's Cottontail. 

 Of the cottontails, this form is the most widely distributed in the 

 state. Mr. Nelson examined specimens from Lawrence, Manhattan 

 and Onaga, as well as from Washington county. It probably oc- 

 curs in the valley of the Kansas river west to the limit of trees. 



Sylvilagus floridanus alacer ( Bangs). Oklahoma Cottontail. 

 Occurs in southern Kansas. Specimens were examined from Gar- 

 den Plain, Belle Plaine and Wichita. 



Sylvilagus floridarius similis Nelson. Nebraska Cottontail. 

 Specimens from Long Island, Kan., were referred to this form, the 

 type of which came from Valentine, Neb. 



Sylvilagus auduhoni haileyi (Merriam). Wyoming Cotton- 

 tail. This form of the small plains cottontail has been taken at 

 Wa Keeney and Pendennis. 



Sylvilagus auduhoni neomexicanus Nelson. New Mexico Cot- 

 ton-tail. Specimens in the Biological Survey collection taken at 

 Kinsley and at Kiowa were formerly referred to Lepus [ Sylvilagus'] 

 arizonm minor, and were so entered on my list of Kansas mam- 

 mals in former papers read before the Academy. They have been 

 assigned by Mr. Nelson to this new form. 



Nyctinomus mexicanus Saussure. Mexican Free-tailed Bat.
