states of preservation, from those that had wholly lost their animal matter to

 still adhered to the horn-cores, and in other cases were found detached but 

 still in a good state of preservation.

 horn-core wdth part of the frontal bone attached, brought home by Mr. Dall, 

 and a metacarpal collected by Mr. Lockhart. A skull of this species, belong- 

 ing to the California Academy of Sciences, and kindly loaned me for exam- 

 ination, is labelled "St. MichaeFs, Alaska," but may have been brought from 

 some point on the Yukon. It thus appears that the remains of the extinct

bison are found throughout a considerable portion of the Territory of Alaska.

In Califoimia the remains of the smaller extinct bison ap-

pear to be of rather frequent occurrence, having been already found at sev- 

 eral different localities, generally associated with the remains of Mastodon 

 Elephas, Tapirus, and Eqims. Dr. Leidy has described a skull from Santa 

 Clara County ; Professor Whitney mentions the occurrence of its remains in 

 Tuolumne County, and Dr. J. G. Cooper has sent a description of a skull 

 found by him in Alameda County, where Dr. L. G. Yates has recently dis-

? 5. Oregon. — A phalangeal bone described by Dr. Perkins is said to have 

 been found twenty feet below the surface, on the " Wolhammet or Multono- 

 mah River," a tributary of the Columbia, associated with the remains of 

 Elephas. The specimen most likely is referable to the present species. 



Prom the foregoing it appears that the remains of this species have been 

 found rather frequently in California and Alaska, and they probably exist at 

 intermediate points. The single specimen from Big-bone Lick, if really 

 identical with the western type, as there seems to be good reason for believ- 

 ing, extends its range to the valley of the Ohio, and there is hence reason to 



suppose, aside from the occurrence in Georgia of specimens possibly refer- 

 able to it, that it may have ranged eastward to the Atlantic coast. Every- 

 w^here its remains occur in association with those of the lars^er extinct
