66 The Ohio Naturalist [Vol. X, No. 4, 



As time passes mammals of many kinds are more and more re- 

 duced on account of the clearing and cultivation of the land. A 

 number of the larger species are already extirpated so far as the 

 state is concerned and others are destined. An effort is being made 

 at present to get together the records in regard to the species of 

 Ohio mammals and to add species as well as records with a view 

 to publishing an annotated list. We have a good representation 

 of many speicies in the museum at present and it is desired to add 

 others. I take this opporttmity to state that we shall be glad 

 to get specimens and records from any part of Ohio, especially 

 of the larger species and such small ones as are considered of 

 rare occurrence within our limits. The porcupine, wild cat, 

 badger, deer and others of very uncommon occurrence may still 

 be in the state if one happens to find them. iVll these have been 

 taken in Ohio in former years, but there are a number of small 

 animals that are suspected of inhabiting the state that have never 

 been reported. Bats, mice and shrews are suggested as groups 

 in which additions are most likely in our fauna. 



A list of Ohio mice as at present constituted follows: 



Zapus hudsonius (Zimmerman). Hudson Ba}' Jumping 

 Mouse. A few specimens of this species have been taken in the 

 state although there is some trouble in separating them from 

 specimens of the following subspecies. Preble, in N. A. Fauna 

 15, reports one from Portland Station, Mahoning county and 

 there is one in the O. S. U. museum from Ira, Summit countv. 



Zapus hudsonius americanus (Barton). Meadow Jumping 

 Mouse. One belittles these interesting little animals by calling 

 them by the mean and unrespected name of mice but the 

 custom is so well established that it is not likely to be changed. 

 They are easily known among Ohio mammals by their jump- 

 ing or bounding mode of locomotion with which are asso- 

 ciated very long hind legs and tail. The varietv is slightly 

 smaller and the dorsal dark area is not so distinct as in the 

 typical species. The two are not easily told apart in the state 

 for it seems that Ohio is largely in the section where thev inter- 

 grade. In parts of the Western Reserve the meadow jumping 

 motise is common and one meets with specimens in various 

 situations and under various conditions. Grass land is one of 

 their favorite haunts but they are often seen in grain fields and 

 in weed covered areas. It is not uncommon to start them while 

 mowing or raking hay and in stvibble ground they may be 

 ploughed out while preparing fields for wheat. The number of 

 young in a brood is variable no doubt but four is the number 

 observed by myself. These quite earlv have nearlv the color 

 of their parents, although for some time, in fact until they are 

 nearly fiill grown, the young are slightly lighter, especially is.
