June 19, 1912; at the steam pump eighteen miles north of 
Tucson) Pima io May 16-18) 1912; Vandy at Eainbanl: 
Cochise Co., August 13-17, 1912. Eggs were found at Tuc- 
son, March 25, 1912; and large tadpoles were taken at the 
same time. 
10.—Kinosternon sonoriense Le Conte 
We have secured twenty Arizonan specimens of this mud- 
turtle. Two (Nos. 17282 and 20643) were collected at Cave 
Creek, Maricopa Co., April 19 and June 29, 1910. One (No. 
35157) was caught at Fairbank, Cochise Co., Sept. 1912. 
The other seventeen (33850 to 33866) are from the Santa 
Cruz River, near Tucson, April 17—-June 4, 1912. This spe- 
cies lives also in the Colorado River at Yuma, whence we have 
a specimen (No. 33403) from the Californian side of the river, 
collected April 8, 1912. This turtle has been recorded also 
from Ash Creek, Guadalupe Canyon, Sabino Canyon in the 
Santa Catalina Mountains, and from the Huachucas. 
Yarrow recorded a specimen from Ft. Yuma, California, as 
Cinosternum flavescens; but I know of no evidence that this 
species occurs in Arizona. Certainly all of the Yuma speci- 
mens sent to the Academy—six or eight before the fire—have 
been Kinosternon sonoriense. 
It would seem that this turtle is generally distributed 
throughout the Gila River and its tributaries. Whether it 
ascends the Colorado River above the Gila is not known. 
Captive specimens ate meat voraciously under water. The 
Tucson specimens were caught with hook and line baited with 
meat. 
11._Terrapene ornata (Agassiz) 
The specimen of this turtle collected by Mr. Price at Fort 
Lowell, near Tucson, June 10, 1893, has remained the only 
Arizonan record of this box tortoise. We now have at hand 
eight alcoholic specimens (Nos. 35148 to 35155) and one skull 
(No. 33156) from Fairbanks, Cochise County, August, 12—- 
18, 1912. These specimens were found in the grass and weeds 
along an old railroad track about a mile out of town. Some 
of these turtles have the plates of the carapace nearly smooth, 
while others are striated. Some are nearly unicolor, while 
others are very distinctly rayed.
