should be included among the mammals of Iowa, since he gives its 

 range as extending eastward to the Big Sioux river and Council 

 Bluffs. It Joes not, however, seem to me to be distinct from the C. 

 virginianuj, 



BOVID^E. 



18. Bos americanus Gmelin. (American Buffalo.) 



Now nearly exterminated in all parts of the State, though numer- 

 ous in the northwestern counties at a comparatively recent date. 

 Two years since I was informed that a few still remained in that sec- 

 tion, and that up to that time one or more had been killed every year 

 as far south as Greene county. Further north they were represented 

 as being more common, but that no herds were met with south of the 

 Sioux river, and rarely east of . the Missouri. Those found further 

 east were only stragglers or wanderers from the herds, that in most 

 cases had probably been driven off by the Indians. 



VESPERTILIONIDJE. 



Bats of at least two species were observed flying about the groves, 

 but I procured no specimens. They were not, however, numerous, 

 and were mainly seen near the timber. A prairie country cannot, 

 evidently, afford such animals favorable haunts ; but they will doubt- 

 less increase with the further settlement of the country, when more 

 or less open buildings will afford them convenient places of resort, 

 The following species, from their general known distribution, doubt- 

 less occur in most parts of the State. 



19. Nycticejus crepuscularis H. Allen. (Black-faced Bat.) 



20. Lasiurus noveboracensis Tomes. (Red Bat.) 



21. Lasiurus cinereus H. Allen. 1 (Hoary Bat.) 



22. Scotophiius fuseus H. Allen. (Brown Bat.) 



23. Scotophiius noctivagans H. Allen. (Silvery Bat.) 



24. Scotophiius georgianus H. Allen. (Georgia Bat.) 



25. Vespertilio subulatus Say. (Little Brown Bat.) 



SORECnXZE. 



During the short time I passed in this State I met with no examples 

 of this family, though several species undoubtedly occur there. Of 

 the long-tailed shrews, or true Sorices, among the species that may be 

 * Probably not distinct from L. noveboracensis.
