DESCRIPTION OF BUFO CANORUS, A NEW 
TOAD FROM THE YOSEMITE 
NATIONAL PARK 
BY 
CHARLES LEWIS CAMP 
(Contribution from the Museum of Vertebrate Zoology of the University of California) 
Included in the material gathered by the Yosemite Natural History 
Survey, and now being worked up at the Museum of Vertebrate Zool- 
ogy under the direction of Dr. Joseph Grinnell, are a number of toads 
of a species which up to the present time has apparently escaped the 
attention of naturalists. Comparison with a large series of toads of 
the boreas group at hand shows that the new species possesses char- 
acters not included within the limits of that variable assemblage. 
Bufo canorus, new species 
Yosemite Park Toad 
Type.—FKemale, adult ; no. 5744, Mus. Vert. Zool.; Poreupine Flat, 
8100 feet altitude, Yosemite National Park, Mariposa County, Cali- 
fornia; July 1, 1915; collected by C. L. Camp; orig. no. 2129. 
Diagnosis—A medium sized toad with no head crests; parotoids 
large, flat, circular, separated by a space usually less than their own 
diameter and never greater; vertebral streak wanting in most males 
and represented in other specimens by a thread-like, white line. Color 
distinctive, and differing greatly in the two sexes; females with irreg- 
ular, dark blotches, each usually bordered narrowly with white; males 
speckled with black on a dull greenish background and without dis- 
tinet dark patches on back.
