(2) Bison occidenialis Lucas. Fort Yukon, Alaska, and Gove 
County, Kansas, in the Quaternary, the Kansas specimen being “a 
practically complete skeleton.” This is a larger species than Z. dzson, 
with well-marked cranial differences. 
(3) Bison antiguus Leidy. Big Bone Lick, Kentucky; Alameda 
County (post-Pliocene gravel) and Pilarcitos Valley, California (blue 
clay, twenty-one feet below the surface). Bison californicus Rhoads 
(Proc. Acad. Nat. Sci., Phila., 1897, p. 501) was based on California 
specimens. 
(4) Bison crassicornis Richardson. Eschscholtz Bay, Alaska. 
(B. alaskensis Rhoads, loc. cit., p. 490). 
(5) Bison alleni Marsh. Pleistocene, Blue River, near Manhattan, 
Kansas (type locality), and Snake River, near American Falls, Idaho.. 
Bison crampianus Cope, 1894, from southern Kanes is considered 
to be the same. 
(6) Bison ferox Marsh. Pleistocene (?) of Nebraska. 
(7) Bison latifrons (Harlan). Big Bone Lick, Kentucky (type 
locality), and Ohio, Texas, Mississippi, South Carolina, Georgia, 
and Florida. Bos arizonica Blake, from Arizona, is referred to this 
species. 
In addition to the above, the following, described as species of 
Bison, have proved not to belong to this genus, namely, Bos scapho- 
ceras Cope, from northern Nicaragua, which proves to be referable to 
the genus Ovis; and Bison alticornis Marsh, based on the horn cores 
of a Dinosaur (Triceratops), as determined later by Marsh himself.

«Wild Animals I Have Known.” ! — This book is unique in con- 
ception and illustration, and the publishers have given it a daintiness 
of form quite in keeping with the delicacy of touch that marks its 
literary and artistic execution. The book is not only as pleasing to 
the eye as it is out of the ordinary in style of make-up, but is one of 
the most valuable contributions to: animal psychology and biography 
that has yet appeared. Mr. Thompson is not only a naturalist and 
an animal artist of very high attainments, but is master of a literary 
style that is at once graphic and fascinating, though doubtless much 
of the charm of the book is due to his sympathetic love of the wild
