NORTH AMERICAN FAUNA. 



[No. 7. 



The present expedition, therefore, not only extends the known range 

 of this species considerably within California, but shows for the first 

 time that it occurs in Nevada as well. The young one from Pahrump 

 Valley has the carapace only 47 mm long, and the plastron is quite soft, 

 while the length of the carapace collected at the Bend of the Colorado 

 is no less than 290 mm . 



[This tortoise is remarkable among American species for its power 

 of living in the arid deserts of the Lower Sonoran zone, far away from 

 water. It is tolerably common in the Mohave Desert, California, where 

 one was caught between Daggett and Pilot Knob, April 24, and 

 another at Leach Point Yalley April 25. Two were found in Pahrump 

 Valley, Nevada, where it is so much sought after by Pah-Ute Indians 

 and coyotes that it is rather scarce. At the Great Bend of the Col- 

 orado many unusually large shells were found about an old Indian en- 

 campment, where they had been left after the bodies had been eaten.—

Clemmys marmorata (B. & Or.), 



The only specimen brought home by the expedition is a young one 

 (No. 18641) collected by Dr. Fisher, July 5, in the South Fork of Kern 

 Biver, 25 miles above Kernville, Calif. It is slightly smaller, but other- 

 wise closely resembles Figs. 8 and 9, PI. xxxii, in the atlas of the 

 herpetology of the United States Exploring Expedition. 



[Dr. A. K. Fisher obtained this turtle and saw many on the South 

 Fork of Kern Biver, about 25 miles above Kernville, early in July, and 

 Mr. Palmer and I saw half a dozen in a small pond 2 or 3 miles above 

 the forks of the Kern June 25.— C. H. M.]
